Document Description
This project proposes the installation of a ramp metering system for sixteen on-ramps/connectors along Route 680 in Alameda County from Scott Creek Road Undercrossing in the City of Fremont to Alcosta Boulevard Overcrossing in the City of Dublin. These on-ramps/connectors are also widened to provide for High Occupancy Vehicle (HOV) preferential lanes or additional mixed-flow lanes. There will be six retaining walls used for the widening. The project also proposes the installation of traffic monitoring stations for four connectors in the corridor.
