Montebello Corridor

Grade Separation Project

City of Montebello

Project Description

The Montebello Corridor Grade Separation project calls for constructing a roadway underpass with sidewalk and bike lanes and railroad bridge at the railroad crossing on Montebello Boulevard and installing at-grade safety improvements at the crossings on Maple, Greenwood and Vail Avenues. A pedestrian overcrossing is planned for the Maple Avenue crossing due to significant numbers of pedestrians and cyclists. Project completion could result in eligibility for a “Quiet Zone” restriction on locomotive horn-blowing in Montebello.

Project Status

Design of the project commenced in 2015, upon approval of the Montebello City Council. The project is currently in the final engineering and design stage. Environmental clearances have been obtained and right-of-way is being acquired. Upon approval of final design plans by the City of Montebello, construction could begin in 2020 and be complete by 2024. The three elements that make up the Corridor Project-the grade separation, at-grade improvements, and the pedestrian overcrossing-will be constructed under three separate construction contracts. The overall estimated project cost is $208.5 million.

Project Benefits

The project would eliminate crossing collisions, queuing and congestion and reduce vehicle emissions at the underpass while improving safety at all four crossings. Ten collisions have been recorded at Montebello’s crossings, resulting in three fatalities and two injuries. By 2025, rail traffic through Montebello is projected to nearly double from 49 trains to 91 trains per day. Without the project, growing train and vehicle traffic will result in an approximate doubling of vehicle-hours of delay at the busiest crossing, Montebello Boulevard, which carries an average of 21,000 vehicles a day.
