Temescal Canyon Bridge and Road Realignment Project

Temescal Canyon Bridge and Road Realignment Project

The existing bridge has been rated as functionally obsolete according to FHWA criteria, with a low sufficiency rating of 68.5. The bridge is considerably undersized and causes flood waters to backup and overtop the bridge deck and its roadway approaches, causing frequent road closures. Constructing a new bridge has been proposed to eliminate these issues and to provide adequate channel cross-section and freeboard to convey 100 year flood waters. The roadway is being realigned to provide adequate distance from the Lake St/I-15 interchange to where Temescal Canyon Rd intersects with Lake St. The project includes the realignment of Temescal Canyon Rd and a new bridge to be built over Temescal Creek. The roadway is being realigned to the project includes a new 98-ft wide, 375 ft long, 4 lane bridge stripped for 2 lanes and a new 649-ft long roadway transition from the bridge to the existing 2-lane Temescal Canyon Rd. The portion of the roadway 696-ft long the will extend from 22 ft south of the bridge to Lake St approx 180 ft south of the current intersection with Lake St will be built by the developer of the Alberhill Villages SP. This portion of the roadway was approved by the city of Lake Elsinore as part of the Alberhill Villages SP EIR SCH No. 2012061046 in February 2017.
