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.

Getting Ready for Bridge Demolition

One of the Stage 1 construction improvements is the Brushy Creek Bridge widening. Dewatering of Brushy Creek was just the first step in preparing the area for the actual bridge construction. The next step is preparing access to the future bridge foundations, establishing a work area in the dewatered creek, and demolishing the existing bridge barrier rail. Teichert Construction began these initial operations earlier this week by adding metal plates over the creek to protect the bypass pipe from construction equipment and demolition debris. A breaker on the back of a backhoe will do most of the demolition work later this week.


A backhoe with a breaker stages on the work side of the k-rail.


Since the k-rail will prevent vehicles from entering the work area where the existing edge of bridge deck (barrier rail) will be demolished, it must be doweled into the existing bridge deck to prevent movement from collisions with vehicles that may have gone astray.


Looking down from the barrier rail (to be demolished), Teichert has established a work area for future falsework and pile driving operatons while protecting the dewatering pipe from construction equipment and demolition debris.
