Full Closure of Monte Vista Avenue As Early as February 14 until Spring 2019

The San Bernardino County Transportation Authority (SBCTA), in cooperation with the City of Montclair and the Union Pacific Railroad, is leading the construction effort on the new Monte Vista Avenue/Union Pacific Railroad Grade Separation in Montclair. This project will construct a grade separation over Union Pacific Railroad tracks along Monte Vista Avenue. The project will improve safety and rail operations, as it will remove the existing at-grade crossing between vehicular, pedestrian and rail traffic. New connector roads, Earnhardt Way and Greenwood Avenue, will allow access between Monte Vista Avenue and State Street. When completed, pedestrians will be able to travel across the grade separation using newly constructed sidewalks along both sides of the bridge.
