Interstate 10: Pepper Interchange, Colton

Located on Interstate 10 in Colton, CA, the new Pepper Avenue Interchange opened in August 2017. In cooperation with the California Department of Transportation, County of San Bernardino, and City of Colton, the project began construction in March 2016 and was completed on schedule. The reconstructed bridge is providing improved freeway access to and from commercial centers, residential communities, and the Arrowhead Regional Medical Center. The completed project provides the following benefits:

  • Five-lane bridge over Interstate 10
  • On-ramp and off-ramp improvements
  • Locally inspired bridge aesthetics, including the City of Colton seal
  • Drainage enhancements

During construction, a total of 12,000 cubic yards of imported material was used. For the bridge structure, 765,000 pounds of steel, 3,000 cubic yards of concrete and 2,500 linear feet of driven piles were installed. Decorative slope paving was constructed. Crews also repaved Pepper Avenue at the ramp intersections and north of the bridge to Valley Boulevard with 4,120 tons of asphalt.
Ramp meters and new traffic signals at the westbound and eastbound on-ramps and off-ramps were installed to help improve traffic flow. 

Funding for this $10.6 million project was provided by a combination of federal, state, city, and local sources, including Measure I, the voter-approved half-cent sales tax for transportation projects in San Bernardino County.
