Project No. 2A <br /> State Route 84 Corridor Improvements: 1-580 to 1-680 <br /> <br />Lead Agency Caltrans, Livermore, Pleasanton and Alameda County <br /> <br />Description This road improvement project is expected to be built in several stages <br /> with a variety of funding sources. The ultimate configuration is expected <br /> to consist of six lanes on Isabel Avenue from 1-580 to Vineyard Avenue <br /> and four lanes from Vineyard Avenue to 1-680. The total length of the <br /> project is about l0 miles. <br /> <br />Cost Estimate $120 million for the roadway portions. (See project 2B for the companion <br /> 1-580 interchange portion of the project.) <br /> <br />Status A two-lane project on Isabel Avenue from 1-580 at the Airway Boulevard <br /> interchange to Vallecitos Road will be completed by 2000. It will include <br /> a grade-separation at Stanley Boulevard. <br /> <br /> Completion of a PSR for all remaining portions of the roadway project is <br /> the logical next step. This will result in definitions, phasing and revised <br /> co. st estimates for future stages of the project. <br /> <br />Funding The TVTC allocates $24 million in future TVTDF funds for this project. <br /> Partial funding for this project may be included in the new Alameda <br /> County Measure B sales tax program. <br /> <br />Schedule The initial two-lane project - Vallecitos Road to 1-580 via Airway <br /> Boulevard - is currently under construction and will be complete in 2000. <br /> <br />Project Need The project would provide improved access to/from southwest portion of <br /> Livermore, including the Ruby Hill development in Pleasanton. It would <br /> also relieve traffic congestion on portions of 1-680 and 1-580. The <br /> projected 2010 PM peak hour volumes (one-way) range from 2,000 to <br /> 3,200 vph, which exceed the capacity of the existing two-lane roadway. <br /> <br /> <br />
