Traffic Signal Modifications

City Project No. 2010-21

This project will modify signals that are nearing the end of their useful life.  Modifications are currently in design for the following intersections:  Vasco Rd at Patterson Pass Rd, Vasco Rd at Brisa St, First St at Old First St, and Railroad Ave at P St.  Signal modifications will improve overall safety operations and progression of traffic along major corridors.

Local Street and Roadway Maintenance

City Projects 2012-01 and 2012-04

The City of Livermore has over 300 centerline miles of streets.  The City uses a  Pavement Management System (PMS) to manage the maintenance of local streets and roadways. Data is collected and updated annually regarding street construction and maintenance history, pavement condition, traffic volumes and more.  This information is used to help staff members make cost effective decisions regarding maintenance, rehabilitation and reconstruction of City maintained streets.  Currently there are two pavement projects in the planning stages for 2012.  One is the annual slurry seal project.  Slurry seal treatment is a cost effective method of extending the life of roadway surfaces. Slurry seal treatment includes the application of asphalt emulsion combined with finely graded aggregate to asphalt paving.   The slurry seal treatment seals small cracks and restores the pavement surface and significantly extends the life of asphalt pavement.  In 2012 the City is planning to slurry seal about 3.8 million square feet of local streets and roadways. 

The second project is the annual overlay project.  When age and traffic cause deterioration of a street to the point where thin surface treatments are no longer effective, an asphalt overly will normally return the street to like-new condition.  A typical overlay treatment consists of 2” of hot asphalt placed and compacted over the existing roadway.  While asphalt overlay is more expensive than a slurry seal treatment, it is considerably less expensive than roadway reconstruction.  In 2012 the City is planning to overlay about 1.3 million square feet of Livermore streets.  Both the slurry seal project and the overlay project are normally conducted in mid summer.

Downtown Iron Horse Trail

City Project No. 2010-40

This project will construct a segment of the Iron Horse Trail to provide a pedestrian connection between the Downtown Livermore ACE station and our Downtown.  The project includes construction of a pedestrian bridge over North Livermroe and the reconfiguration of South Oak Street to accommodate the trail.

Vineyard Ave. Realignment at Vallecitos Road

City Project No. 1996-60

This project will realign a portion of E. Vineyard Avenue and relocate the intersection of E. Vineyard Avenue at Vallecitos Road.  The project will provide turn lanes, acceleration lanes, and a new traffic signal.

State Route 84 Expressway

As the new State Route 84, Isabel Avenue is ultimately planned to be 6-lanes from I-580 to Stanley Boulevard, and 4-lanes from Stanley Boulevard to Vallecitos Road. The 2002 Measure B expenditure program identifies $70 million for the Route 84 (Isabel) Expressway.

The Alameda County Transportation Improvement Authority (ACTIA) and the City of Livermore are performing engineering and design analysis for Cal Trans for the State Route 84 Expressway widening project. The environmental document for these improvements dated August 2008 can be viewed on the Cal Trans website. The project fact sheet can be viewed at the ACTIA website.

The Isabel Avenue improvement projects have been largely funded through the Measure B Sales Tax Program. For more information on other local Measure B projects click here.
