The Western Contra Costa County Transit (WestCAT) was established in August 1977 as a Joint Exercise of Powers Agreement between the County of Contra Costa and the cities of Hercules and Pinole. It was created with the purpose of owning, operating and administering a public transportation system serving the area between the Richmond/El Sobrante border to the west and the Al Zampa Memorial Bridge to the east. WestCAT is governed by a 7-member Board of Directors and supported by professional staff of six. The two cities of Pinole and Hercules are each represented by two board members, while the unincorporated communities of Crockett, Rodeo, and MonTaraBay each have one representative, appointed by the Contra Costa Board of Supervisors.
WestCAT's fleet started out with shuttle vans, and then using buses made by El Dorado National and Thomas Built Buses. Now, WestCAT runs an almost all Gillig fleet, ranging from Gillig Phantoms, to 2 Gillig Low Floors serving mostly the 16 - Pinole Valley/Pinole Vista route, as well as 11 new 2007 model Gillig BRT buses that are now in service. In addition, WestCAT now has two new Motor Coach Industries (MCI) over-the-road coaches for use on the LYNX.
