Niles Boulevard Bridge Replacement

The Niles Boulevard Bridge Replacement recently received the 2018 APWA Northern California Chapter Public Works Project Award for Transportation Projects between $5M-$25M.

 

The original bridge in Fremont was constructed in 1970 to span over the new BART tracks as well as a UPRR track. This project began as a seismic retrofit with Caltrans’ Local Agency Seismic Retrofit Program with Jeff completing the design and John the independent check of a $1M retrofit. This work was completed in 1999. About 5 years later, Caltrans agreed to fund a replacement bridge. Originally Quincy was hired to design the bridge, with the new roadway to be designed by the City. Eventually the City of Fremont asked Quincy to design the roadway as well. After several years of delayed reviews and approval, the construction was just completed earlier this year. This project is a testament to Quincy Engineering’s perseverance, as it took 19 years to finally complete the project!

Alhambra Valley Road Washout Repair

Quincy Engineering recently won the 2018 APWA Northern California Chapter Disaster or Emergency Construction Repair Project Award (for projects under $5M).

 

The heavy storms in early 2017 caused extensive damage when a large culvert backed up and the entire roadway was washed away in rural Contra Costa County. Quincy provided fast-track construction management, inspection, and administration; permit compliance; and materials testing services to Contra Costa County for the repair of this major roadway/culvert washout with a single-span, precast voided slab, concrete bridge. The project also reconfigured the intersection of Castro Ranch, Pinole Valley, and Alhambra Valley Roads to eliminate the free-right lane from Castro Ranch onto Alhambra Valley Road. These modifications accommodate the constant superelevation needed for the new bridge as well as to improve intersection safety and operations. Additional project components included the following:

  • Adding rock slope protection to the Pinole Creek channel under the new bridge

  • Removing from the channel debris from the damaged culvert and roadway

  • Protecting and ultimately placing underground and on the bridge Comcast fiber-optic lines (currently overhead)

  • Installing site fencing and signing and adding striping

 

This project was funded using Federal FHWA Emergency Relief monies.
