Document Description
Note: Final IS/EA Caltrans, in cooperation with the City of Brea (City), proposes to improve the SR 57/Lambert Road interchange from post mile 20.1 to PM 21.8. The proposed project would improve traffic operations on SR-57 and Lambert Road, in the interchange area. Improvements would include widening the southbound SR-57 median shoulder, reconfiguring the northbound and southbound SR-57 on- and off-ramps, lowering the Lambert Road profile to provide 15-foot standard vertical clearance under the Lamber Road Undercrossing and widening Lambert Road from 1,000 feet west of State College Blvd to Pointe Drive, and reconfiguring the north and southbound SR-57 on- and off-ramp/Lambert Road intersections.
