Title
State Route 84 Expressway Widening Project
Description
The existing 40-foot-wide and 121-foot-long, two-span bridge at Arroyo del Valle will be widened by 54 feet to the east to accommodate the larger SR 84 widening project. A new two-span bridge will be constructed across Arroyo del Valle to accommodate the Isabel Trail extension. The existing 61-foot wide and 123-foot-long, three-span SR 84 bridge at Arroyo Mocho will be widened by 71 feet to the west to accommodate the larger roadway widening project. Excavation and driven pile foundations will be required for widening the bridge abutment and pier foundations. A new single-span bridge will be constructed across Arroyo Mocho (Arroyo Mocho Access Bridge) to provide private access to PG&E, City of Livermore, and Zone 7 facilities. The CDFW is executing a Lake and Streambed Alteration Agreement No. 1600-2016-009-R3 pursuant to Section 1602 of the Fish and Game Code to the project Applicant, Caltrans.
