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.

Single lane controls- Vasco Rd (Alameda) Sept 21-23

Vasco Road will be under single lane controls between the hours of 8am and 5pm on September 21, 22 and 23. Traffic will be subject to 30 minute delays. The work causing the delays occurs on the Alameda County job, south of the County line on Vasco Road. The contractor will be reconstructing the existing shoulder area directly adjacent to traffic lanes causing the need to shut down an entire lane (only one lane open to handle both directions of traffic). The message boards at either end of the work have been changed to notify road users of this upcoming lane closure and 30 min delay to traffic.

Paving and Barrier installed




The past 3 weeks have been busy on Vasco Road. As the calendar turned to September, the County's contractor, Teichert Construction, completed the paving operation along the east side of Vasco Road (5 mi south of Camino Diablo). This work marked the footprint of this project's total pavement widening. During this 3-day paving operation (September 1, 6 and 7), Teichert installed approx. 5,600 tons of hot mix ashphalt concrete pavement.

Following the paving operation, Teichert installed the center concrete median barrier for approximately 1 mile in length down the new road centerline. This work was done by a special extrusion machine which moved about 2 feet per second average through the project area. Pictures attached.

Vasco Road Delays

With the recent start of Alameda County's project to install an approx 1 mile long median barrier on Vasco Road, the route from Livermore to Brentwood on Vasco Road is subject to delay. Contra Costa County will be diligent in informing the road users via the portable message boards of upcoming work causing lane closure and associated delays to traffic. Please note that jurisdiction changes at the County line and work in Alameda is under different management. For any questions on the Contra Costa County portion of the work (or any questions on Vasco), please call Neil Leary (925) 313-2278. (Note: Neil replaces Warren Lai as the County contact). For any questions on the Alameda project, please call inspector Danny Guzman at (510) 670-6606.

There will be significant work on Vasco Road in both Alameda and Contra Costa County over the next two months causing delay to traffic. Contra Costa is committed to notifying road users in advance so that you can make other commute plans if necessary.
