MARIN – Caltrans District 4 (Bay Area), will continue construction work on Stage 2 of the Northbound (NB) US-101 Central San Rafael off-ramp bridge (Harbor Bridge replacement) in Marin County.

Additionally, on Sunday, June 20, starting at 11:00 PM to Monday, June 21, ending at 6:00 AM, the construction team will change the off-ramp configuration to a two-lane configuration. This new configuration will provide for one lane to the new temporary bridge, and one lane to the existing off-ramp.
