Interstate 80 Westbound HOV/Bus Lane
Part of the Bay Bridge Forward commute initiative, the Interstate 80 Westbound HOV/Bus Lane project proposes adding a high-occupancy vehicle (HOV) lane to westbound Interstate 80 (I-80) between the Powell Street Interchange and the Bay Bridge toll plaza.
Overview
The Interstate 80 (I-80) westbound HOV lane and the HOV connector ramp (also known as the I-80 flyover ramp) serves HOV traffic on the I-80 corridor. The I-80 flyover ramp provides a direct connection to the San Francisco-Oakland Bay Bridge toll plaza, allowing buses and HOVs to bypass a major bottleneck north of the I-80/I-880/I-580 junction. Heavy traffic congestion in the vicinity of the I-80 Powell Street interchange can prevent buses and HOVs from accessing the I-80 flyover ramp.
MTC – in partnership with Alameda County Transportation Commission – proposes adding an HOV lane to the outside of the westbound I-80 between Powell Street Interchange and the Bay Bridge toll plaza. This project will benefit transit vehicles entering from the Powell Street interchange, as well as other HOVs traveling on westbound I-80 that cannot use the existing leftmost HOV lane due to congestion. This project seeks to:
- Improve the operational efficiency and travel time for buses and HOVs on westbound I-80;
- Move more people through the area during peak hours; and
- Encourage carpooling and transit use.
