Title

I-580 Roadway Rehabilitation Project in Alameda County

Description

Caltrans proposed to rehabilitate the pavement of eastbound I-580, from the San Joaquin County Lin to one mile east of North Flynn Road and the mainline of Westbound I-580/I-205 from the San Joaquin County Line to Greenville off-ramp in Alameda County. A second distinct location occurs on I-580 between the Eden Canyon Road Undercrossing and the Strobridge Avenue Undercrossing in Alameda County. Rehabilitation of the pavement will include adding overhead safety signs, replacing dikes, concrete curbs, metal beam guardrails, and concrete barriers, placement of shoulder backing, embankment reconstruction, adjusting existing drainage inlets to grade, replacing bridge approach slabs, and adding polyester concrete overlay on Midway Road Undercrossing and California Aqueduct Bridge. The project will also meter and rehabilitate 12 existing on-ramps, two of which will be widened to provide for a High Occupancy vehicle preferential lane or Mixed Flow Lane, Maintenance Vehicle Pullouts and CHP pullouts.
