Document Title
I-680 HOV Direct Access Ramps Project
Document Type
NOP - Notice of Preparation of a Draft EIR
Received
Present Land Use
I-680 Freeway
Document Description
The project would construct HOV (carpool, vanpool, bus, etc.) on- and off-ramps connecting directly to and from the northbound and southbound median HOV lanes of I-680 in the City of San Ramon between Bollinger Canyon Road and Crow Canyon Road. The proposed HOV on- and off-ramps and auxiliary lanes would be added in the median, and therefore the I-680 mainline lanes would need to be shifted to the outside. Both directions of the proposed I-680 mainline would have one 12' HOV lane, three 12' mixed-flow lanes and one 12' auxiliary lane, in compliance with current highway design standards for lane widths.
