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 Commission (ACTC) 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 ACTC 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.
