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.

EXPECT DELAYS: 6/24

Teichert Construction will be implementing 1 lane traffic control along Vasco Rd (at Brushy Creek bridge) on Thursday, 6/24/10, from 9 am to 3 pm. Commuters should expect delays while County biologists work on the bridge to re attach netting to prevent birds from nesting on the bridge structure itself. Surprisingly, the concrete angle points on bridges are prime habitat for birds to form "mud" nests. Birds that form new homes on the bridge may delay the project so County biologists monitor and implement measures to prevent birds from establishing nests. On Brushy Creek bridge, netting is installed under the bridge at the abutments and along the edge of deck. Due to the high winds, netting must be constantly maintained and reattached to prevent it from blowing onto the roadway itself or falling into the creek, which is sensitive habitat.
