State Route 74 Shoulder Widening Project
The project proposes to widen the existing shoulder on State Route 74 (SR-74) to a continuous 4-foot shoulder in both directions, install centerline rumble strips, construct turn-outs and install metal beam guard rail (MBGR) at various locations. Shoulder widening will require roadway excavation and embankment in certain cut and fill sections. Construction of retaining walls will be required. Most existing culverts within the project limits will be replaced. This project begins from east of Antonio Parkway/La Pata Avenue (PM 2.93) to west of Conrock Entrance (PM 5.06) in an unincorporated area of the County of Orange.
