The F-line will be operated solely with buses on Saturday, February 22, so that a number of projects can be carried out on Market Street. This includes completion of the removal of the old switches that led to and from the now-vanished Transbay Terminal (specifically, the switch at Fremont and Market), plus utility work at Spear and Market and crosswalk repair at Third and Market. F-line buses will operate on Market, except between First and Fremont inbound, where they will detour via Mission. Trolley coaches will be replaced by motor coaches along Market, as the overhead wires will be deenergized between Tenth and Steuart.
