Project No. 5 <br /> 1-580 HOV Lanes from Tassajara Road to <br /> Vasco Road <br /> <br />Lead Agency Caltrans ~ <br /> <br />Description Construction of approximately 8.2 miles of High Occupancy vehicle <br /> (HOV) lanes on 1-580 from Tassajara Road to Vasco Road. After addition <br /> of these lanes, 1-580 would have a total of four mixed lanes and one HOV <br /> lane in each direction in this segment. Widening of 1-580 and additional <br /> right-of-way may be required. <br /> <br />Cost Estimate $40 million <br /> <br />Status A PSR is needed to define the project, determine usable segments, and <br /> refine project costs. The PSR should consider the entire corridor, which <br /> includes HOV lanes in each direction, BART in the median, and auxiliary <br /> lanes between interchanges. <br /> <br /> There are current or recent PSRs in process for nearly all 1-580 <br /> interchanges within the proposed project limits; the main line PSR would <br /> resolve and combine traffic issues related to the individual PSR projects. <br /> <br />Funding The TVTC allocates $8 million in future TVTDF for this project. This <br /> project may be eligible for regional gas tax funds and may be included in <br /> the new Alameda County Measure B sales tax program. <br /> <br />Schedule This project is not presently scheduled. Because of growing congestion on <br /> 1-580, completion of the PSR is a very high priority. <br /> <br />Project Need This project is needed to increase overall person-trip capacity in the <br /> freeway corridor. Traffic forecasts show a demand for travel on 1-580 of <br /> up to approximately 10,600 vph (vehicles per hour) in the peak direction. <br /> This exceeds existing capacity. Added lanes would encourage HOV's, <br /> potentially reducing SOV (single occupancy vehicle) trips as well as <br /> increasing overall capacity. Added capacity would also complement added <br /> capacity related to 1-580/I680 interchange improvements. <br /> <br /> <br />
