The Vasco Rd Safety Improvements Project - Phase 1 is designed to improve the safety of approximately 1 mile of Vasco Rd between the cities of Brentwood and Livermore. This stretch of twisting Vasco Rd has heavy, fast moving traffic and a history of serious injury accidents. The project consists of installing a concrete median barrier along the 1 mile project limits and widening the southbound pavement to provide a truck climbing lane, thereby eliminating the gap in the existing truck climbing lanes along Vasco Rd. To accommodate these safety improvements, 6 retaining walls, storm drains, wildlife crossings, and a bridge widening will be constructed. This project is anticipated to take 1.5 yrs (2 construction seasons) to complete, anticipated in December 2011. Check out this blog from time to time to see updates on construction progress and facts about the project.

Cast In Place Facing Walls

Teichert Construction has completed portions of the Cast in Place (CIP) facing walls that will ultimately provide the architectural facing along all the retaining walls on Vasco Rd. Upon completion of the soil nail installation and shotcrete facing walls, a CIP wall is then installed to create the final wall face and grades along the future road shoulder widening. A concrete barrier will be installed at the bottom of the wall, to "mirror" the future median barrier.
