Marsh Drive Bridge Replacement

Marsh Drive Bridge Replacement Over Walnut Creek

Contra Costa County Public Works Department and Bridgeway Civil Constructors, Inc have teamed up once again to replace the Marsh Drive Bridge over Walnut Creek. The two-stage project began in June 2021 and is expected to be completed by October 2022. The purpose of the project is to replace the existing bridge that was built in 1938 with a new 5 span cast in place/prestressed voided slab bridge that will have two lanes of vehicular traffic and a 10-foot-wide separated bike and pedestrian facility on the south side of the bridge in its final configuration. All superstructure has been designed to be supported by cast-in-drilled-hole concrete piles and cast in place concrete columns. The new bridge will be raised approximately seven feet to meet hydraulic standards with 500 linear feet of roadway approach work to improve the roadway alignment and horizontal curve. Other work items included in the project include bridge removal, utility relocation, cast in place retaining wall, decorative bridge rail, rock slope protection and improvements to the Iron Horse Trial and Floodplain access roads.

SR 880 Deck Replacement

SR 880 Deck Replacement

This project consisted of removing and replacing a bridge deck (29.67’ wide by 458.29’ long) on Southbound SR 880 while preserving the existing cast-in-place girders, bent caps and hinges. The work occurred in Alameda Creek, an active water channel which required a water diversion system. To ensure no damage occurred to the existing superstructure two temporary support systems were required, longitudinally and transversely. Other aspects of the work included a slope stability analysis, bird deterrent, rapid strength concrete (RSC), joint seal replacements, carbon fiber reinforced girders and accelerated work to complete the project within the in-creek working window from June 15th, 2021, to October 15th, 2021. The temporary support systems reinforced the bridge structure and existing girders as crews cut and removed 3-ton panels off the bridge deck. This work was performed behind k-rail placed along SR 880 while still allowing vehicles to exit the southbound off-ramp to Alvarado-Niles Blvd. Pedestrian routes were also maintained underneath the bridge on the Alameda Creek Trail. Crews completed the in-creek work prior to the October 15th deadline and final work for the Joint Seal Replacements concluded March 25th, 2022.

Chico Rte. 99 Multi-Bridge Retrofit & Widening

Chico Retrofit & Widening

The Route 99 bridge retrofit and widening project consists of retrofitting 5 existing bridges by constructing new barrier slabs, adding new concrete barrier rails, and installing Carbon Fiber Reinforced Polymer Strips (CFRP). The retrofit of these bridges is intended to extend the overall working life of these structures. The bridge widening occurred at the Western Canal located along the Route 99 Corridor between Gridley and Chico. The widening added 6 feet of shoulder as a preventative measure to increase public safety within the area. The project was constructed in 3 stages, with the first two stages consisting of the retrofit for the 5 existing bridges and the third stage that was dedicated to Western Canal as the allowed window for construction was from January through March. The widening of Western Canal consisted of partial demolition of the existing structure, pouring of new footings, pier walls, and abutments. The final portion of work at Western Canal consisted of installing falsework for the widening of the bridge deck surface.
