Project No. 6 <br /> 1-680 HOV Lanes from State Route 84 to <br /> Top of Sunol Grade <br /> <br /> .. <br />Lead Agency Caltrans <br /> <br />Description Construction of approximately 3.5 miles (seven total lane-miles) of HOV <br /> lanes on 1-680 from the SR 84 ramps to the top of Sunol Grade at Mission <br /> Pass. After adding these lanes, 1-680 would have three mixed lanes and <br /> one HOV lane in each direction of this segment. <br /> <br />Cost Estimate Construction of the southbound 1-680 HOV lanes between Route 84 and <br /> Calaveras Boulevard in Milpitas is expected to cost approximately $90 <br /> million. The portion within the Tri-Valley (Rt. 84 to the top of the Sunol <br /> Grade constitutes about 35 percent of the total mileage, or approximately <br /> $29 million. <br /> <br />Status This project to construct the highest priority southbound HOV lanes has <br /> committed funding from other sources. It is likely the northbound HOV <br /> lane will receive outside funding also. This is a regional project that <br /> involves three counties, the CMAs, Caltrans, and MTC. In addition, the <br /> 1-680 Phase II Corridor Study will address future needs of the corridor. <br /> <br />Funding Almost all of the southbound HOV lanes project funding is now committed <br /> ($84 million) from outside sources. The northbound HOV lanes are <br /> currently unfunded. No TVTDF funds are included for this project. <br /> <br />Schedule A PSR has been completed for the project. Environmental studies and <br /> preliminary engineering are underway. <br /> <br />Project Need The southbound lanes of 1-680 through the Sunol Grade constitute the <br /> second most congested commute in the Bay Area. Congestion occurs for <br /> a three to four hour period each week day. <br /> <br /> r T ' <br /> <br /> <br />
