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.

Soldier Pile Wall 2 Work Begins

Teichert Construction began construction of Soldier Pile Wall 2 at the southern project limit. Besides the use of soil nails to secure the hillside along Vasco Rd, soldier pile wall retaining systems will be used to stabilize the minor hillside cuts. Approximately 20 to 30 ft deep holes are drilled to accommodate concrete cast in place steel piles. Timber lagging will be installed in between the steel piles prior to the final concrete facing wall. Upon completion Soldier Pile Wall 2 will be approximately 12 ft tall at the highest location.
