I-80 Bridge Rehabilitation Project

Project Facts

Description

This project is demolishing and rebuilding four Interstate 80 bridge overcrossings in Placer County: Crystal Springs, Baxter, Drum Forebay and Cisco Grove. All overcrossings are being widened to include 8-foot shoulders, 6-foot sidewalks and will include ramps that comply with Americans with Disabilities Act (ADA) standards.

Purpose and Need

The purpose of this project is to replace the deficient structural components at four overcrossing locations along Interstate 80. Due to the severity of the transverse and longitudinal cracks in the concrete decks, spalling concrete, and high corrosive chloride content in the concrete deck surfaces, bridge superstructures and substructures are in need of major replacement.

Funding/Cost Estimate

This project is funded through the State Highway Operation and Protection Program (SHOPP). It also includes $3.48 million in funding from Senate Bill 1 (SB 1), the Road Repair and Accountability Act of 2017.

Support Cost: $16.3 million
Capital Cost: $40.8 million
Total Cost: $57.1 million
