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.

SR 99 Sacramento Bridge Deck Replacement

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.

Pollock Pines Highway 50 Retaining Wall Construction

Highway 50 Retaining Wall

The Highway 50 Retaining Wall Construction Project consists of constructing a 428 foot long retaining wall made up of 58 Cast In Drilled Hole (CIDH) piles ranging from 60 feet to 115 feet in length, 252 ground anchors that will be drilled through the CIDH piles, forming and pouring a barrier slab, installing a new barrier rail, installing timber lagging between the CIDH piles, and repaving of the highway. The retaining wall construction is intended to prevent further landslides in the area which have previously damaged the highway. The project will be constructed in two stages, with the first stage consisting of installing the CIDH piles, and the second stage consisting of installing the ground anchors, timber lagging, barrier slab, and repaving the highway.

San Joaquin SR99 Farmington Bridge Replacement

Farmington Bridge Replacement

This bridge project was funded through Caltrans State Highway Operation and Protection Program. Our work at the Farmington Road Bridge Replacement project over SR99 in the City of Stockton consists of replacing the existing bridge to improve vertical clearance in order to eliminate bridge strikes and cost repairs. The new Post-Tensioned Box Girder Bridge replacement design is approximately 50 feet wide and 190 feet long with two columns supports at the center of the bridge span. The project includes extensive utility work and landscaping with decorative fencing and architectural slope paving.

SR 680 at Scott Creek Road Retaining Wall

I-680 Pavement Rehabilitation and Ramp Metering, Caltrans #04-3G6034, (Subcontractor to Bay Cities Paving and Grading, Inc.)

Another project to add to the group of 680 projects. This is another ramp widening project that will also add metering lights to the on-ramp at Mission Blvd. We will be teaming up with Bay Cities again to create some great continuity for the work along the 680 corridor. The scope for our work on this project will be another 900 cubic yards of Retaining Wall, and almost 200 driven pile, and joint seal replacement.

SR 99 Slope Paving, Gore Paving and MVPs

Stockton Gore and Slope Paving, Caltrans Contract #10-0X6404

This project consisted of 14 gore paving locations, 12 slope paving locations, and 6 maintenance vehicle pullouts along Highway 99 from Stockton to Lodi. The gore paving areas were treated with a brick stamp pattern and a red color hardener to provide a greater aesthetic appeal. We partnered with Caltrans to change the staging on the MVP’s to provide a more efficient process and reduce the impact to the travelling public. The slope paving operation was the most challenging aspect of the project. Access was limited due to the proximity of the freeway and the steep slopes made any use of equipment nearly impossible. Our team members worked together to create a plan to perform the work safely and executed each aspect to near perfection.

SR 4 and SR 24 Gore Paving and MVP

Rte 4 and Rte 24 Gore Paving, MVP and Vegetation Control, Caltrans #04-4G9804

The scope of the project is to construct Maintenance Vehicle Pullouts (MVPs), Gore Paving, and Vegetation Control at various locations along Highway 4 and Highway 24. The project is 140 working days and will begin in early February with a total of 171 locations to be constructed. The first order of work will be to install k-rail at the gore locations that will be constructed first. Construction will begin in Hercules and move eastbound on Hwy 4 to Pittsburg and then back to Hercules in the westbound direction. The MVPs and vegetation control will follow after the construction of the gore paving. Some of the challenges that we will have to overcome are the slopes in which the vegetation control will be placed because the existing slopes in some areas of Hwy 4 start at the back of pavement. Scheduling will also provide a challenge for the project because a majority of the work will be performed at night so communication between the project team, the crews, and suppliers will be critical to ensure the project progresses smoothly and efficiently.

SR 680 at Bernal Avenue Retaining Wall

I-680 Ramp Metering and Traffic Operating Systems, Caltrans #04-4G1154, (Subcontractor to Bay Cities Paving and Grading, Inc.)

Essentially an add-on to the larger I-680 project, we will once again be a subcontractor to Bay Cities to construct 1,000 cubic yards of retaining walls including over 400 driven pile. Construction access will once again be minimal, but, with our ingenuity and experience, it will not be anything too large to overcome. This project will fit in perfect with the rest of the work being performed on I-680 and we will be a major contributor to the success of these construction projects.
