Interstate 80 HOV Lane Access Restrictions

Part of the Bay Bridge Forward commute initiative, the Interstate 80 HOV Lane Access Restrictions is one of several projects that aim to improve traffic congestion for the Interstate 80 (I-80) corridor between the Carquinez Bridge and the San Francisco-Oakland Bay Bridge.

 

Overview

This project proposes to implement access restrictions along select segments of the existing high-occupancy vehicle (HOV) lanes on the Interstate 80 corridor between the San Francisco-Oakland Bay Bridge and the Carquinez Bridge. Access restrictions are expected to improve traffic flow in the HOV and general purpose lanes by limiting merges between lanes in congested areas.

Currently, the HOV lane is separated from general traffic by a dashed line, which indicates that it is OK to enter and exit the HOV lane at any point. Project 6b would add lane access restrictions by replacing the existing lane striping and painting double solid white lines between the existing HOV lane and the general-purpose lane, to restrict vehicles from entering or exiting the HOV lanes at select segments. Double white lines indicate it is illegal to enter and exit the lane.
