 A full-scale bus rapid transit corridor is currently under construction along the route of line 1, variously "International BRT" or "East Bay BRT", with some station canopies already complete.The most substantial planning alternative proposed for this system would feature articulated buses with five to six doors at boarding platform level, a separated bus-only lane, center median platforms in many areas with proof-of-payment ticket machines to speed boarding, and signalization priority to allow bus drivers to change traffic lights in passengers' favor.This project will go into service in March 2020.
