Proposals to widen the portion of Route 92 from Route 92/880 Interchange to the high-rise portion of San Mateo-Hayward Bridge from 4 to 6 lanes. The scope of the project includes a new 60 foot wide trestle on the north side of the existing trestle, mainline metering and a new mini toll plaza with Electronic Toll Collection. The east approach widening consists of two (2) structures widening, one structure replacement, a new pedestrian/bicycle overcrossing and an additional auxiliary lane. The westbound HOV (car pool lane) lane will be extended 1 mile east to the Hesperian on-ramp.
ENVIRONMENTAL AND COAST GUARD ISSUES
Permits from the following regulatory agencies are required: U.S. Coast Guard, San Francisco Bay Conservation and Development Commission (BCDC), U.S. Department of Army, Corps of Engineers, Construction and Maintenance Agreement with Union Pacific, Regional Water Quality Control Board.
U.S. Coast Guard is the lead agency for the environmental review and will be issuing a bridge permit that constitutes a project approval. The proposed work will not reduce horizontal clearance at the main shipping channel between Piers 19 and 20. The contractor will be required to prepare a mooring plan and preconstruction check list identifying numbers and placement of barges/boats along the bridge. The DEIS/R was approved for circulation on March 17, 1997. Public hearings were held in April 1997. The Final Environmental Approval is expected in May 1998. Nick Mpras from the Coast Guard was instrumental in adjudicating a dispute among various federal agencies. His leadership has allowed this critical project to move forward.
