Via Avenue Bridge

City of Atascadero
Atascadero, California

Project Summary

The Via Avenue Bridge crosses Atascadero Creek and had been classified as structurally deficient due to its narrow width. It was demolished and replaced with a curved, superelevated, single-span, cast-in-place post-tensioned concrete slab bridge.

Earth Systems provided materials testing and special inspection services for the Via Avenue Bridge project, which was awarded the 2023 Transportation Project of the Year ($5 million to $25 million) by the Central Coast Chapter of the American Public Works Association (APWA).  The project was funded by grants through the Federal Highway Administration Program, administered through Caltrans Local Assistance District 5.

Earth Systems’ scope during construction included:

  • Concrete sampling and testing during caisson drilling and pouring
  • Abutment
  • Bridge deck and bridge rail pouring Coordination of gamma-gamma log testing
