Project Description

This $2 million dollar transportation project encompassed the design plans for the replacement of the entire western approach structure of the Mare Island Causeway. Improvements included the construction of a 52-foot long simple span concrete structure, the replacement of approach road asphalt concrete (AC) pavement, the realignment of an existing 14-inch water main (with an 18-inch main), new sidewalks, curb ramps, and decorative steel bridge railings, and new pavement striping, markings, and markers. Design required ongoing coordination with Caltrans (District, Headquarters, and Office of Structures Local Assistance) and adherence to the Caltrans Local Assistance Procedures Manual (LAPM).
