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.

Completion of Soil Nails

By mid November, Teichert Construction completed installation of all the soil nails associated with Walls 4, 6, and 7. Over 900 nails were installed in the hillside to secure the slopes to the recently formed shotcrete walls. Nail lengths varied from 15 ft to 60 ft deep into the hillside. A fractured fin texture will become the final finish when the cast in place facing walls are poured next.
