In April 2017, SamTrans identified fifteen potential express bus routes connecting the Peninsula counties of San Francisco, San Mateo, and Santa Clara. Most of the potential routes ran along U.S. 101, and some were planned to take advantage of managed lanes to provide speedier service. By June 2018, the list of potential bus routes was reduced to six. The draft final report was released in November 2018, and the Board adopted it in December. SamTrans anticipates relaunching express bus service in August 2019 from Foster City to downtown San Francisco along U.S. 101. Then a second route in Spring/Summer of 2020 from Palo Alto to western San Francisco along I-280.
