The California Cycleway, opened in 1900, was a nine-mile elevated tollway built specially for bicycle traffic through the Arroyo Seco, intended to connect the cities of Pasadena and Los Angeles, in California, United States.
The inventor and promoter of the cycleway was Pasadena resident Horace Dobbins, who attracted ex-California governor Henry Harrison Markham to join him in the venture. Together, the two sought approval from the California state legislature, which was ultimately granted (after a first attempt was vetoed) in 1897. The California Cycleway Company bought a six-mile (10 km) right-of-way from downtown Pasadena to Avenue 54 in Highland Park, Los Angeles.
Construction began in 1899, and about 1.3 miles (2 km) of the elevated wooden bikeway were opened on January 1, 1900, starting near Pasadena's Hotel Green and ending near the Raymond Hotel. The majority of its route is now Edmondson Alley. A toll booth was located near the north end, in the present Central Park. Had the full route been completed, it would have continued past Highland Park, on through Montecito Heights, crossed the Los Angeles River, passed Elysian Park, and continued to the Plaza in Los Angeles. The full nine-mile run would have had a maximum grade of 3% and an average grade slightly over 1%. At its highest point, the elevation of the roadway was 50 feet (15 m).
The portion built was constructed almost entirely of Oregon pine and was wide enough for four cyclists to ride abreast, with provision for eventual doubling of the width. It was painted dark green and, at night, brightly lit with incandescent lights. The toll was 10 cents one-way, or 15 cents round trip.
Due to the end of the bicycle craze of the 1890s and the existing Pacific Electric Railway lines connecting Pasadena to Los Angeles, the cycleway never made a profit, and never extended beyond the Raymond Hotel into the Arroyo Seco. In the first decade of the 20th century, the structure was dismantled, and the wood sold for lumber, and the Pasadena Rapid Transit Company, a failed venture headed by Dobbins to construct a streetcar line, acquired the right-of-way. Later, the California Cycleway's right-of-way became part of the Arroyo Seco Parkway (Pasadena Freeway).
