The G Line Bikeway is a cycle route in Los Angeles County, California, that runs for 17.9 miles (28.8 km) from Chatsworth, through Sepulveda Basin Recreation Area to Valley Glen.

[8] Because of the long reach of the extended path, this route has been called a “San Fernando Valley commuter corridor”[9] and “the crown jewel of San Fernando Valley bike infrastructure.”[10] The path was opened in 2005 as a 12 mi (19 km) route between Warner Center and North Hollywood.

[11][12] The county added 4 mi (6.4 km) in 2012 “between Canoga station and the Chatsworth train station.”[13] The construction project included bioswales to reduce water pollution from urban runoff and “recycled construction debris from the 405 expansion project “crushed and used as an underground base.”[14] According to the website of County Supervisor Zev Yaroslavsky, “Most of the wide, asphalt-surfaced path has separate, dedicated lanes for bicyclists and pedestrians.

Wider than usual 6 ft (1.8 m) curb ramps also will allow cyclists and pedestrians to get on and off the path more easily, especially when it’s crowded.”[14] For those wishing to transfer from the bike path to the bus and vice versa, “G (Orange) Line buses pretty much all hold three bikes, though racks fill quickly, so it’s easiest to board at the ends of the line in North Hollywood or Chatsworth.”[6] A 2015 study of “cycling transit users” (CTUs) of the G Line found: “(1) CTUs are more likely to be stranded during weekday nights due to the proximity to three major colleges; on weekends, CTUs are more likely to be stranded in the mornings; (2) Metro’s policy that increased evening service during 2013 successfully decreased the number of stranded cyclists; and (3) when the racks are two-thirds full, approximately 20 percent of buses will strand at least one cyclist.”[15] Dedicated ”park and ride” parking lots are available at Chatsworth, Sherman Way, Canoga, Pierce College, Reseda, Balboa, Sepulveda, and Van Nuys stations.

[17] There is a “dangerous blind curve on the east end of the Canoga Avenue station.”[9] Transient encampments and overgrown landscaping may intermittently obstruct the path.
