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 Road (Nov 1, 4, 5, and 6)

Vasco Road will be under single lane controls through the Contra Costa County median barrier project on November 1, 4, and 5. Traffic will be subject to 30 minute delays from 8:30am to 3:00 pm on the weekdays and from 7am until 6pm on the weekend (Nov 5).

Alameda County also is planning work on Vasco Road that will put the road on single lane controls on November 1, 5 and 6. With both projects (Alameda and Contra Costa County) causing delay on November 1 and 5, the travelling public may be subject to up to 1 hour of delay on those days.

The work in Contra Costa County causing the delay is final signing and striping.

The work in Alameda County causing the delay is paving of the roadway.

Vasco Road delays--Oct 8, 10, 11, and 12; Final Paving date Set

Vasco Road will be subject to delays the following days:

Saturday October 8-- Contractor to remove k-rail (temporary concrete barrier rail) which is no longer necessary for traffic control since the center median barrier is in place and the K-rail conflicts with the upcoming asphalt paving work. One lane of traffic will be made available to each direction of through traffic throughout this operation but in a temporary location via cones/delineators. Speeds will be reduced to 25 mph through the site and may be stopped at points during day to move construction vehicles in and out.

Monday, October 10--Contractor to prepare existing pavement for asphalt concrete overlay by grinding off areas of existing pavement, construction staking will also be done in preparation for the upcoming paving work; Through public traffic will be under single lane traffic controls--subject to 30 min delay

Tuesday, October 11--Continuation of work from Monday (if necessary)--traffic subject to 30 min delay

Wednesday, October 12-- Contractor to install final lifts of asphalt paving to the western side of the project. This work completes the asphalt paving for this project. Contractor expects to work from sun up to sun down (7am to 7pm) to complete this work. Both directions of public through traffic will be pushed to the east side of the roadway via cones/delineators. Traffic will not be delayed during this paving operation but they will be routed through the area in a new location for duration of the work and subject to 25mph speed limit. Following the paving work both lanes of traffic will be returned to the west side of the road via temporary markers/delineators. Permanent striping will be installed within one week of paving putting traffic in the final, finished configuration--northbound traffic on the east side of the new median barrier and southbound traffic on the west side of the new median barrier.
