SR-74 Lower Ortega Highway Widening

The California Department of Transportation (Caltrans) is proposing to widen State Route 74 (SR-74) in the City of San Juan Capistrano (City) and unincorporated Orange County. The total length of the project is 1.1 miles (mi). The project proposes to widen SR-74 from two lanes to four lanes from Calle Entradero (Post Mile [PM] 1.0) to 150 feet (ft) east of the City/County boundary (PM 1.9) with restriping from 150 ft east of the City/County boundary to Reata Road (PM 2.1).The project will provide one additional 12-ft lane in each direction, and a 12 ft painted median at the western portion within the project limits. A paved 5-ft and 8-ft shoulder will be provided on each side of the roadway to accommodate Class II (striped on-road) bicycle facilities. The shoulder will be 8 ft wide from Avenida Siega to the City/County boundary to merge with the completed county portion. The proposed work may affect a historic property eligible for the National Register of Historic Places. Caltrans is evaluating alternatives and determine if the project can avoid adversely affecting the property or, if not, if adequate mitigation measures can be incorporated into the project plans. 

Information in the Environmental Assessment (EA) describes why the project is being proposed, the proposed Build Alternative being considered, the environmental impact evaluation, and proposed avoidance, minimization and/or mitigation of potential impacts associated with the proposed Build Alternative.
