SR 99 Sacramento Bridge Deck Replacement Project

The Highway 99 Sacramento Bridge Deck Replacement Project consisted of demolishing the existing bridge deck, replacing the bridge deck with pre-cast girders, placing Ultra High-Performance Concrete (UHPC) in the joints of the pre-cast girders, replacing 250 LF of Type 60MG center median rail, removing and replacing 1,000 SF of masonry block soundwall, placing 7,000 SF of polyester concrete overlay, and placing 215 tons of rubberized hot mix asphalt (RHMA). To complete the work, a 100-hour full closure of SR 99 from Business 80 to 47th Avenue was required. The project’s intent was to replace the severely damaged bridge deck that was constructed nearly 50 years ago. The intent of the project was to complete all work within a 100-hour closure and Bridgeway was able to complete the work within 94 hours, 6 hours ahead of schedule.
