Interstate 580 Westbound HOV Lane Extension
Part of the Bay Bridge Forward commute initiative, the Interstate 580 Westbound HOV Lane Extension project proposes to extend the existing high-occupancy vehicle (HOV) lane on westbound Interstate 580 to reduce traffic backup during morning peak hours.
Overview
The Interstate 580 (I-580) westbound corridor serves as an approach to the San Francisco-Oakland Bay Bridge and is a key transbay commute corridor that connects the East Bay to San Francisco.
The corridor experiences heavy traffic congestion during morning peak hours, with traffic backing up to the Interstate 980 (I-980)/State Route 24 (SR-24) interchange.
MTC – in partnership with Alameda County Transportation Commission – proposes to extend the existing HOV lane on I-580 westbound to the area by the I-980/SR-24 interchange as a near-term improvement.
The I-580 Westbound HOV Lane Extension Project seeks to:
- Move more people through the corridor during peak hours.
- Improve travel time reliability to support buses and HOVs.
- Provide time travel savings for HOV and transit users, to encourage people to carpool or take transit.
The project proposes to convert a portion of the far-left lane of westbound I-580 to an HOV lane. From just east of the Piedmont Avenue undercrossing in Oakland, the new HOV lane would connect with the existing HOV lane at the toll plaza approach (just west of the MacArthur maze), a distance of approximately 2.3 miles.
