I-66

Interstate 66 (I-66) is an Interstate Highway in the eastern United States. As indicated by its even route number, it runs in an east-west direction. Its current western terminus is near Middletown, Virginia, at an interchange with I-81;[2] its eastern terminus is in Washington, D.C., at an interchange with U.S. Route 29.[3] Because of its terminus in the Shenandoah Valley, the highway was once called the "Shenandoah Freeway."[4] Much of the route parallels U.S. Route 29 or Virginia State Route 55. Interstate 66 has no physical or historical connection to the famous U.S. Route 66 which is in a different region of the United States.

The E Street Expressway is a spur from Interstate 66 into the Foggy Bottom neighborhood of Washington, D.C.

Evening rush hour traffic on I-66 westbound, as seen from eastbound lanes near Centreville, Virginia

Because I-66 is the only Interstate Highway running west from Washington, D.C., into Northern Virginia, traffic on the road is often extremely heavy. For decades, there has been talk of widening I-66 from 2 to 3 lanes each way inside the Capital Beltway (Interstate 495) through Arlington, Virginia, although many Arlington residents are adamantly opposed to this plan.

In 2005, the Virginia Department of Transportation (VDOT) studied the prospect of implementing a one-lane-plus-shoulder extension on westbound I-66 within the Beltway (in an attempt to reduce congestion for people commuting away from D.C.).[5]

In the summer of 2010, construction began on a third lane and a 12-foot shoulder lane between the Fairfax Drive entrance ramp (near George Mason Drive in Ballston) to I-66 west and the Sycamore Street ramp, a 1.9 mile distance. The entrance ramp acceleration lane and the exit ramp deceleration lanes were lengthened to form a continuous lane between both ramps. The 12-foot shoulder lane can carry emergency vehicles and can be used in emergency situations. This project was completed in December 2011.[6]

The Orange Line and the Silver Line of the Washington Metro operate in the median of the highway in Fairfax and Arlington counties. Four stations (Vienna, Dunn Loring, West Falls Church, and East Falls Church) are located along this segment of I-66.

I-66 east has two exit ramps, one from each side of the highway, to the Inner Loop of I-495 heading northbound. One is a two lane right exit which merges down to one lane halfway along the ramp, while a second exit ramp is a left exit; the latter reserved for use by high-occupancy vehicle (HOV) traffic during morning rush hour, but open to all traffic excluding trucks at all other times. Both exit ramps for the Inner Loop merge prior to merging from the left with the Inner Loop. There is no access from the Outer Loop of I-495 to I-66 east; traffic wishing to make this movement must use State Route 267 east.

I-66 east also has two exits, one from each side of the highway, to the Outer Loop of I-495. One is a right exit, while one is a left exit; the latter shares a ramp with the exit to the Inner Loop of I-495.

I-66 is named the "Custis Memorial Parkway" east of the Capital Beltway in Virginia.[7] The name commemorates the Custis family, several of whose members (including Martha Dandridge Custis Washington, George Washington Parke Custis, Eleanor (Nellie) Parke Custis Lewis and Mary Anna Randolph Custis Lee) played prominent roles in Northern Virginia's history.

HOV designation and rules

Due to heavy commuter traffic, I-66 features a variety of high-occupancy vehicle (HOV) restrictions. Between US 15 in Haymarket, Virginia and the Capital Beltway, the left lane on eastbound I-66 is reserved for vehicles with two or more occupants (HOV-2 traffic) from 5:30 to 9:30 a.m. on weekdays, and the left lane on westbound I-66 is reserved for HOV-2 traffic from 3:00 to 7:00 p.m on weekdays. The eastbound shoulder lane (far right lane) between US 50 in Fairfax, Virginia and the Beltway is open to all traffic from 5:30 to 11:00 a.m on weekdays. The westbound shoulder lane (far right lane), also between the Capital Beltway and U.S. Route 50, is open to all traffic from 2:00 to 8:00 p.m on weekdays.[8]

Between the Beltway and the Theodore Roosevelt Bridge, the entire eastbound (inbound) roadway is reserved for HOV-2 and Washington Dulles International Airport traffic from 5:30 to 9:30 a.m., and the entire westbound (outbound) roadway is reserved for HOV-2 and Dulles Airport traffic from 3:00 to 7:00 p.m. This is enforced by random police presence on the on- and off-ramps, because single-passenger vehicles are allowed to enter the highway inside the Beltway in the direction of rush-hour traffic when they intend to use the Dulles Access Road also called Virginia State Route 267 at exit 67. Police heavily monitor the three-mile stretch between the Dulles Access Road and the Beltway for violations also on Virginia State Route 267 between the on and off ramp to Washington Dulles International Airport and I-66 , frequently having traffic slow down to visually inspect inside each vehicle.[9]

Both motorcycles and qualified "clean special fuel" vehicles are permitted to use HOV-2 facilities on I-66 during times when HOV regulations are in effect even without the required number of occupants. The "clean special fuel" designation is used primarily by hybrid vehicles, but is also available for vehicles using alternative fuels such as natural gas or electricity.[10] To qualify for the HOV exemption, a vehicle owner must specifically request the designation when registering the vehicle, pay the appropriate fees, and display a "clean special fuel" license plate. The clean-fuel exemption is scheduled to expire on June 30, 2012, although the Virginia General Assembly has extended the exemption every year, one year at a time, since it was originally designated to expire in 2006.[11] In 2011, the exemption was modified so it applies only to clean fuel vehicles registered before June 30, 2011. Clean-fuel vehicles registered after that date are not exempt from HOV regulations on I-66. In 2012, the exemption was modified to be "open-ended" rather than year-to-year.[12]

As of January 28, 2011, penalties for HOV violators range from $125 on the first offense to $250 on the second offense, $500 on the third offense, and $1,000 on the fourth offense. Violators also receive three points on their driving record on the second and later offenses.[13]

Outside the Beltway improvement project

The Virginia Department of Transportation (VDOT) Transportation planning board has added I-66 HOT lanes to their list of priority projects for the I-66 corridor.[14] The project has sparked opposition between residents and community businesses over the direction of this region's future infrastructure planning. The VDOT set up a website Transform 66 on regional traffic issues, and residents on the I-66 corridor set up Transform 66 Wisely, a website with local community impacts as a result of the VDOT project. Many local business groups and Chambers of Commerce located near the affected areas voiced support for transportation improvements in the I-66 region.[15]

Residents along the I-66 corridor such as Arlington County have resisted I-66 widening proposals for a long time.[16] The local Stenwood Elementary School would lose its attached field, leaving it with blacktop-only recess space.[17] In an April 16, 2015, letter to the Virginia Secretary of Transportation, members of the 1st, 8th, 10th, and 11th districts of Congress wrote that VDOT research noted that during peak hours, 35% of eastbound cars and 50% of westbound cars are HOV violators.

Future federal steps for VDOT include NEPA review, obligation of federal funds, certification that the conversion to tolled facilities will not "degrade" the existing facility, and potential federal loan guarantee. The Virginia Commonwealth Transportation Board (CTB) is responsible for overseeing VDOT and allocating highway funding to specific projects. The board has 18 members appointed by the Governor [18] and includes the Virginia Secretary of Transportation, Aubrey Layne, and is the group that will be making the final decision and allocating funding for VDOT's plans for I-66.

Construction is expected to begin in 2017.[19]

Inside the Beltway improvement project

With the I-66 Inside the Beltway program, solo drivers will be able to use the Interstate during peak hours, in exchange for paying a variable congestion pricing toll. The price will be designed to keep traffic moving at a minimum of 45 mph (72 km/h) and increase the capacity of the road. Carpools and vanpools (with two or more people, until a regional change to HOV-3+ goes into effect in 2020), transit, on-duty law enforcement and first responders will not pay a toll.[20] Prices ranged up to $47 USD for solo drivers, but the average speed during the morning rush hour was 57 mph (92 km/h), vs 37 miles per hour (60 km/h) a year before.[21]

District of Columbia

View "west" (actually south) at the eastern terminus of I-66 at US 29 in Washington, D.C.

In Washington, D.C., I-66 follows the West Leg of the Inner Loop freeway. After crossing the Potomac River on the Theodore Roosevelt Bridge concurrent with US 50, the route quickly turns north, separating from US 50. The highway interchanges with the E Street Expressway spur before passing beneath Virginia Avenue in a short tunnel. After an indirect interchange with the Rock Creek Parkway (via 27th Street), the highway terminates at a pair of ramps leading to the Whitehurst Freeway (US 29) and L Street.[22]

This is the only 2 digit Interstate to enter the District of Columbia on land. I-95 crosses DC waters for approximately 100 yards (91 m) along on the Woodrow Wilson Bridge (part of the Capital Beltway).

E Street Expressway

View east along the E Street Expressway just east of I-66

The E Street Expressway is a spur of I-66 that begins at an interchange with the interstate just north of the Roosevelt Bridge. It proceeds east, has an interchange with Virginia Avenue NW, and terminates at 20th Street NW. From there, traffic continues along E Street NW to 17th Street NW near the White House, the Old Executive Office Building, and the Corcoran Gallery of Art. Westbound traffic from 17th Street takes a one-block segment of New York Avenue to the expressway entrance at 20th and E Streets NW. The expressway and the connecting portions of E Street and New York Avenue are part of the National Highway System.

History

Virginia

Interstate 66 in Fairfax County outside of the Capital Beltway, with the Metrorail Orange Line in the median. The left lane is HOV, and the right shoulder is used as a travel lane during rush hour. The Deteriorated Concrete pavement shown in this picture which stretched from Exits 57-64 is now covered with a 4-inch thick asphalt overlay

I-66 was first proposed in 1956 shortly after Congress established the Highway Trust Fund as a highway to connect Strasburg, VA in the Shenandoah Valley with Washington.[24][25]

Entrance to I-66 in Arlington, describing the travel restrictions imposed in exchange for construction

During the planning stages, the Virginia Highway Department considered four possible locations for the highway inside the Beltway and in 1959 settled on one that followed the Fairfax Drive-Bluemont Drive corridor between the Beltway and Glebe; and then the Washington and Old Dominion (W&OD) corridor between Glebe Road and Rosslyn. The route west of 123 was determined earlier. Two other routes through Arlington neighborhoods and one along Arlington Boulevard were rejected due to cost or opposition.[26] I-66 was originally to connect to the Three Sisters Bridge, but as that bridge was cancelled, it was later designed to connect to the Potomac River Freeway via the Theodore Roosevelt Bridge.[27]

On December 16, 1961, the first piece of I-66, an 8.6-mile-long section from US-29 at Gainesville to US-29 at Centreville was opened. A disconnected 3.3-mile-long section near Delaplane in Fauquier County opened next in May 1962.[28]

In July 1962, the highway department bought the Rosslyn Spur of the W&OD for $900,000 and began clearing the way, such that by 1965 all that remained was dirt and the shattered foundations of 200 homes cleared for the highway.[29][30][31] In February 1965, the state contracted to buy 30.5 miles of the W&OD from Herndon to Alexandria for $3.5 million and the C&O petitioned the ICC to let them abandon it. The purchase would eliminate the need to build a grade separation for I-66 and would provide 1.5 miles of right-of-way for the highway, saving the state millions.[32] The abandonment proceedings took more than three years, as customers of the railway and transit advocates fought to keep the railroad open, and delayed work on the highway.[33] During that time, on November 10, 1967, WMATA announced that it had come to an agreement with the Highway Department that would give them a 2 year option to buy a five mile stretch of the right of way from Glebe Road to the Beltway, where I-66 was to be built, and run mass transit on the median of it.[34] The W&OD ran its last train during the summer of 1968 thus clearing the way for construction to begin in Arlington.

While the state waited on the W&OD, work continued elsewhere. The Theodore Roosevelt Bridge opened on June 23, 1964 and in November of that year the section from Centerville to the Beltway opened. A 0.2 mile extension from the Roosevelt Bridge to Rosslyn opened in October 1966.[28]

After the Virginia Department of Transportation (VDOT) (then known as the Virginia Department of Highways) took possession of the W&OD right-of-way in 1968, they began to run into opposition as the highway revolts of the late 1960s and early 1970s took hold. In 1970, the Arlington County Board requested new hearings and opponents began to organize marches.[35][36] A significant delay was encountered when the Arlington Coalition on Transportation (ACT) filed a lawsuit in Federal District Court in 1971 opposing the Arlington portion of the project. The group objected to that urban segment due to concerns over air quality, noise, unwanted traffic congestion, wasteful spending, impacts on mass transit and wasted energy by auto travel.[24] In 1972 the U.S. Fourth Circuit Court of Appeals ruled in favor of ACT, technically blocking any construction. The U.S. Supreme Court upheld the ruling in favor of ACT later that same year.[37]

Again, work continued elsewhere and in October 1971, the 6.6-mile-long section from I-81 to US-340/US-522 north of Front Royal opened.[28]

In July 1974, a final environmental impact statement (EIS) was submitted.[38] The EIS proposed an eight-lane limited access expressway from the Capital Beltway to the area near Spout Run Parkway.[38] Six lanes would branch off at the Parkway and cross the Potomac River via a proposed Three Sisters Bridge.[38] Another six lanes would branch off to the Theodore Roosevelt Bridge.[38] In November, a modified design was submitted, reducing the eight lanes to six. However, in 1975, VDOT disapproved the six-lane design.[38]

I-66 westbound access in Rosslyn, Arlington County

The parties then agreed on experts to conduct air quality and noise studies for VDOT, selecting the firm of ESL Inc., the expert hired originally by ACT. In 1976, United States Secretary of Transportation William Thaddeus Coleman, Jr. intervened. On January 4, 1977, Coleman approved federal aid for a much narrower, four-lane limited access highway between the Capital Beltway and the Theodore Roosevelt Bridge.[38] As part of the deal, Virginia officials agreed to provide more than $100 million in construction work and funds to help build the Metro system, which has tracks down the I-66 median to a station at Vienna in Fairfax County; to build a multi-use trail from Rosslyn to Falls Church; and to limit rush-hour traffic mainly to car pools.[38][39][40] Three more lawsuits would follow, but work began on August 8, 1977 moments after U.S. District Court Judge Owen R. Lewis denied an injunction sought by highway opponents.[41]

In the late 1970s and early 1980s the highway's final miles were built. A 2.9 mile long section from Delaplane to US-17 east of Marshall was completed in 2 sections in 1978 and 1979. The 15.6-mile-long section from US-340 to Delaplane was completed in August 1979. A 12 mile section between US 17 in Marshall and US 15 in Haymarket opened in December 1979, with the gap between Haymarket and Gainsville closed on Dec. 19, 1980.[42] The final section of I-66, in Arlington, was completed between the Capital Beltway and the Theodore Roosevelt Bridge on December 22, 1982.[38][28]

The Custis Trail, the trail along I-66 built between Rosslyn and Falls Church as a concession, opened in the summer of 1982, before the highway was complete. The Dulles Connector between I-66 and the airport opened in 1984.[38] The Metrorail in the median of I-66 from Rosslyn to Vienna, another concession, opened on June 7, 1986.

After opening, the restrictions on use began to loosen. In 1983, Virginia dropped the HOV requirement from 4 to 3,and then from 3 to 2 in 1994. In 1992 motorcycles were allowed.[38]

On October 9, 1999, Public Law 106-69 transferred from the federal government to the Commonwealth of Virginia the authority for the operation, maintenance and construction of I-66 between Rosslyn and the Capital Beltway.[43]

In 2004-05, Virginia studied options for widening the highway inside the Beltway. They later settled on three planned "spot improvements" meant to ease traffic congestion on westbound Interstate 66 inside the Capital Beltway. The first one, a 1.9-mile zone between Fairfax Drive and Sycamore Street, started in 2010 and was finished in 2011.[44] The second one widened 1.675 miles between the Washington Boulevard on-ramp and the ramp to the Dulles Airport Access Highway. Work on it began in 2013 and finished in 2015.[45] The third project, between Lee Highway and Glebe Road, is scheduled for completion in 2020.[46]

In Gainesville, Virginia, the Gainesville Interchange Project upgraded the interchange between U.S. Route 29 (U.S. 29) and I-66, for those and many other roads due to rapid development and accompanying heavy traffic in the Gainesville and Haymarket area. I-66's overpasses were reconstructed to accommodate nine lanes (six general purpose, two HOV, one collector-distributor eastbound) and lengthened for the expansion of U.S. 29 to six lanes. These alterations were completed in June 2010. In 2014-15, US 29 was largely grade-separated in the area, including an interchange at its current intersection with SR 619 (Linton Hall Road). The project began in 2004 and finished in 2015.[47]

In 2016, VDOT announced that it was planning to add express lanes and multi-modal transportation improvements to I-66 outside the beltway, and dynamic tolling during rush hours in the peak directions and multimodal improvements to I-66 inside the beltway. In addition, the decision was made to move forward with widening I-66 eastbound from the Dulles Connector Road to Ballston.[48]

On December 4, 2017, 10 miles (16.1 km) of I-66 between Route 29 in Rosslyn and Interstate 495 were converted to a High Occupancy Vehicle variable tolling system, allowing solo drivers to use I-66 during rush hour if they paid a toll.[49]

A diverging diamond interchange in Haymarket at the interchange with US 15 was completed in August 2018.[50]

In 2017, construction began on the Transform 66 Outside the Beltway improvement project. The project will add 22.5 miles (36.2 km) of new dynamically-tolled Express Lanes alongside I-66 from I-495 to University Boulevard in Gainesville. It will also build new park and ride facilities, interchange improvements and 11 miles (17.7 km) of expanded multi-use trail. VDOT expects the project to be completed in December 2022.[51]

Construction on widening eastbound I-66 as part of the Transform 66 Inside the Beltway improvement project began in June 2018 and is expected to be completed in 2020. The project will add a travel lane on eastbound I-66 between the Dulles Access Road (Virginia State Route 267) and Fairfax Drive (Exit 71) in Ballston, will provide a new ramp-to-ramp direct access connection from eastbound I-66 to the West Falls Church Metro station at the Leesburg Pike (Virginia State Route 7) interchange and will provide a new bridge for the W&OD Trail over Lee Highway (Virginia State Route 29).[20]

District of Columbia

The Potomac River Freeway (I-66) in Washington, D.C.

In Washington D.C., I-66 was planned to extend east of its current terminus along the North Leg of the Inner Loop freeway. I-66 would have also met the eastern terminus of a planned Interstate 266 at US 29, and the western terminus of the South Leg Freeway (I-695) at US 50; I-266 would have been a parallel route to I-66, providing more direct access to the North Leg from points west, while I-695 would have been an inner-city connector between I-66 and I-95.

A map of I-66, showing cities, and interchanges with I-81 and I-495.

The final plans for the North Leg Freeway, as published in 1971, outlined a 1.5-mile (2.4 km) six-lane tunnel beneath K Street, between I-266/US 29 and New York Avenue, where the North Leg would emerge from the tunnel and join with the Center Leg Freeway (formerly I-95, now I-395); the two routes would run concurrently for three-fourths of a mile before reaching the Union Station interchange, where I-66 was planned to terminate. Despite the plan to route the North Leg in a tunnel beneath K Street, the intense opposition to previous, scrapped alignments for the D.C. freeway network, which included previous alignments for the North Leg Freeway, led to the mass cancellation of all unbuilt D.C. freeways in 1977, resulting in the truncation of I-66 at US 29.

Interstate 266 (I-266) was a proposed loop route of I-66 between Washington, D.C., and Arlington County, Virginia. District of Columbia officials proposed designating the route Interstate 66N, a move opposed by the American Association of State Highway and Transportation Officials. In Virginia, Interstate 266 would have split off from Interstate 66 just east of the present Spout Run Parkway exit. From there, it would have followed an expanded Spout Run Parkway, crossed the George Washington Memorial Parkway, and crossed the Potomac River across a new bridge that would have been called the Three Sisters Bridge. Upon entering the District of Columbia, it would have followed Canal Road and an expanded Whitehurst Freeway to rejoin Interstate 66 at K Street. Interstate 266 was canceled in 1972 in the face of community opposition during Washington's "freeway revolts".[54][55]
