To further advance options for alternative modes of travel within the County of Marin, the Transportation Authority of Marin (TAM) and Golden Gate Transit (GGT) joined together to seek grant funding to replace the 2-position, exterior mounted bike racks with new exterior mounted racks capable of carrying 3 bicycles. In 2008, grant funding was secured through a Bay Area Air Quality Management District “Transportation Fund for Clean Air" grant administered by TAM.

GGT’s fleet of 10 articulated 60 foot-long-buses are already equipped with the 3-position exterior bike racks. These coaches are used exclusively within Marin County to provide local bus services on routes with high-passenger capacity demands. GGT provides these services under a contract with Marin County Transit District (Marin Transit). TAM, Marin Transit, and GGT will continue to partner to identify initiatives such as the bike rack replacement program to improve travel options within Marin County.

With installations beginning on July 7, 2009, GGT will be expanding its bike carrying capacity by upgrading its 2-position bike racks to 3-position bike racks on 90 of its buses. With 3-position racks all ready mounted on GGT’s 10 articulated coaches, once installations are completed, there will be 100 buses in the fleet of 204 buses equipped with 3-position racks. Installations will be completed later this summer.

After extensive testing, there are three different bus models in the GGT fleet that cannot be mounted with the 3-position bicycle racks due to safety concerns with the racks blocking headlights on curb side of the buses. In addition, under state law, GGT’s 45-foot-long buses cannot accommodate the 3-position racks but will retain the 2-position “underbelly” luggage racks.

Additional Background

In July 1999, GGT launched its Bike Racks on Buses program with the installation of front-mounted, 2-position, exterior bike racks on GGT’s 40-foot-long buses. At that time, state law prohibited the installation of the bike racks on GGT’s 45-foot-long buses. In October 2006, a solution for the 45-foot-long buses came to fruition, when all of GGT’s high-capacity, 45-foot long MCI buses were equipped with racks accommodating two bikes inside the luggage bays.


TAM is designated as both the congestion management agency (CMA) and the transportation sales tax authority for Marin County. As the CMA, TAM addresses Marin's unique transportation issues, fulfilling the legislative requirements of Propositions 111 and 116, approved in June 1990. TAM was designated the sales tax authority in 2004, for the purpose of administering the 1/2 cent transportation sales tax in Marin County, passed by voters in November 2004 as Measure A. TAM is responsible for managing a variety of transportation projects and programs in Marin County, receiving federal, state, regional, and local funds, working closely with all eleven cities and towns as well as the county.

Marin County Transit District (Marin Transit) was formed by a vote of the people of Marin County in 1964 and was given the responsibility for providing local transit service within Marin County. Although Marin Transit has responsibility for local services, it does not own any buses or facilities and does not employ its own drivers. Instead, Marin Transit contracts with other providers, including Golden Gate Transit and Whistlestop Wheels for local bus and paratransit services. To learn more visit,
