initiated inter-county paratransit service, as required by the Americans with Disabilities Act), through an agreement with Marin County and its paratransit contractor, Whistlestop Wheels. Significant service reductions were implemented in 2003 as a result of a declared fiscal emergency. As a result of the restructuring, all GGT service to the Sonoma Valley and Sebastopol was eliminated. Ferry Feeder bus routes to the ferry terminals in Larkspur and Sausalito were also discontinued. This fiscal emergency helped spur the passage of Measure A by Marin County voters in 2004. The sales tax measure established a new funding source for Marin Transit and was a catalyst for changes to the contract the District had with Marin Transit. Marin Transit assumed control over local bus service planning, and it began transitioning some service to private contractors. On June 15, 2009, Golden Gate Transit began operating Route 101, which provides all-day service between Santa Rosa and San Francisco with fewer stops, similar to many bus rapid transit "light" systems that rely on stop spacing changes rather than capital improvements to speed up buses. Introduced initially as a weekday-only route, service was expanded to Saturdays in June 2010 and to Sundays and holidays in September 2011. On December 13, 2015, service to Contra Costa County on Route 42 was merged with Route 40. The next day, service began on Route 580, which was the District's first transit line into nearby Alameda County. The latter experiment failed and Route 580 was discontinued in September 2016, however the numeric designation was revived when Route 40 was renumbered to Route 580 in December 2021. GGT buses returned to Alameda County in February 2019 to provide Early Bird Express bus service under contract with BART. As a result of declining ridership due to the COVID-19 pandemic and the resulting loss in operating revenue, including a reduction in Golden Gate Bridge tolls, bus service was dramatically reduced throughout 2020. GGT had 27 routes at the beginning of the pandemic and just seven routes by December 2020. In March 2022, Route 4C was revived as Route 114.
