I-80 Six Bridges Project Overview
Caltrans has scheduled to begin work on increasing the vertical clearance on six bridges that cross over Interstate 80(I-80) in the City of Vallejo just north of the Carquinez Bridge. The bridges are on I-80 just north of the Carquinez Bridge, in this order going northerly (I-80 is officially designated as westbound/eastbound route but travels north and south within Vallejo): Magazine Street, Benicia Road, Georgia Street, Springs Road, Tennessee Street and Redwood Street.
The six bridges do not meet the current vertical clearance design standard of 16 feet 6 inches. Each bridge will be completely closed to local traffic for four months of construction, day and night. Detours will be provided, and extensive public outreach will take place in order to advise the public about the project, the schedule, and the detours.
The bridges will be constructed one at a time, starting with Springs Road, then Magazine Street, Benicia Road, Georgia Street, Tennessee Street, and Redwood Street.
Once all six bridges on I-80 meet the latest standard vertical clearance height, it will accommodate large commercial permit vehicles, so they can continue to safely move freight through I-80, a major freight corridor connecting San Francisco Bay Area to the regions in the north. The bridges will be constructed one at a time, taking about four months each to complete the work. Doing this work now ensures the continued safety of the bridges and prevents the need for more comprehensive and disruptive work in the future.
