Title

State Route 86/Avenue 50 New Interchange Project

Description

Note: Review Per Lead The city of Coachella, in cooperation with Caltrans, proposes the construction of a new interchange at SR 86 (PM R19.2/R21.6) and Avenue 50, approx 1.1 miles north of the existing SR 86/Avenue 52 intersection and 1.95 miles south of the existing SR-86/Dillon Rd interchange. The proposed project would convert a portion of SR 86 from an at-grade signalized intersection into a grade-separated full interchange with a new overcrossing bridge and access ramps. This new overcrossing would be up to approx 326 ft long and 122 ft wide. It would be a 2-span structure to accommodate 3 through lanes in each direction and two left-turn pockets for the eastbound and westbound directions of Avenue 50. The project would also construct a new bridge structure over the Whitewater River/Coachella Valley Stormwater Channel. The new bridge structure over the CVSC would be approx 605 ft long and 120 ft wide, would be a 5-span structure to accommodate 3 through lanes in each direction and a 14-ft wide median on Avenue 50, and would replace the existing at-grade paved low water crossing. The construction of the bridge for Avenue 50 over the CVSC would also include realignment and widening of a portion of Avenue 50 from the existing two-lane roadway to a six-lane major arterial, and realignment of portions of Tyler St on both the west and east sides of SR-86, respectively, and, the existing 1-lane in each direction road that is located within the limits of the CVSC would become a CVSC maintenance road. The project will be constructed in two phases.
