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.

Alameda County to begin median barrier project August 22

Alameda County has issued a notice to proceed to their contractor to begin work on August 22 on a project that includes installation of one mile of a concrete median barrier to be placed along the centerline of Vasco Road from the County line to the Los Vaqueros Reservoir entrance road in Alameda County. Contra Costa County is in contact with Alameda County to coordinate traffic control efforts to minimize the impact to the traveling public along this busy commute corridor. Teichert Construction will be the prime contractor for both the Alameda County project as well as Contra Costa County's safety improvement project to widen the road and install a center median barrier. Having one contractor on both projects will ensure good coordination between projects.

August 17 and 18 single lane controls on Vasco Rd

On August 17 and 18 Vasco Road will be under single lane controls so that the Contractor, Teichert Construction, can perform crack sealing on the existing asphalt concrete pavement. This work is needed to prolong the life of the existing pavement section and precedes an asphalt concrete overlay scheduled for later in August. Expect up to 20 minutes of delay when traveling on Vasco Road through the project area during these dates.

Project update

On the night of July 12th, traffic lanes were reset on Vasco Road so that the contractor can begin stage 3 work along the east edge of the road. This move allows the contractor to begin the construction of the new pavement widening along the east edge of the road which includes over 40 feet of pavement widening in areas. After the pavement work is complete later in the month of August, the contractor will begin work on the center concrete median barrier. Project work is nearly 80 percent complete. The project is expected to be complete by December 2011.

August 8 and 9 single lane control on Vasco Road

Vasco Road will be under single lane traffic controls on August 8 and August 9, 2011 so that the Contractor, Teichert Construction, can install hot mix ashpalt across the roadway. The traveling public should expect up to 20 minutes of delay on these dates.

Traffic Shift July 13th; Single Lane Controls July 6, 7

Teichert Construction will be shifting the traffic configuration on Vasco Road during the night of July 12th. The work to implement the Stage 3 Traffic Configuration will begin the night of July 12th and possibly carry over into the next night as necessary. The travelling public will see a new traffic configuration on the roadway on July 13th. The message boards situated along Vasco Road will notify Vasco Road traffic of the changes beginning on July 8th.

On July 6th and 7th Vasco Road will be under single lane traffic controls between 8:30 am and 3:30 pm so that project work can be completed. The message boards along Vasco Road will notify the travelling public of these traffic controls beginning on July 1.

Construction Season is Here!

Construction of the Vasco Rd Safety Improvements Project continues into the 14th month. Construction Stages 1 and 2 are now complete with the recent paving work that was installed by Teichert Construction’s paving crews on June 2 and June 3. Stage 3 work, the final work stage, officially begins later this month with the shifting of public traffic onto the new pavement along the west project edge. The shift of traffic will allow for the grading and paving work to begin along the east edge of the project. The shift will also allow for the construction of the center concrete median barrier--the project’s primary feature. The large retaining walls that line the roadway edges are nearly complete with only facing elements left to install. The storm drain and wildlife culvert crossings of Vasco Road are now complete which will reduce the need for signal lane traffic controls. The project is still on track to be completed by December 2011.
