Montebello Corridor

Grade Separation Project

City of Montebello

Project Description

The Montebello Corridor Grade Separation Project is comprised of three separate components which impact four current at-grade crossings with the Union Pacific Railroad (UPRR) within the City of Montebello.


Montebello Boulevard Grade Separation Project: Construction of a bridge at the UPRR crossing at Montebello Boulevard and at Olympic Boulevard, creating a roadway underpass at both.
 

At-Grade Safety Improvements: Upgrades to the signals at the Greenwood Avenue and Vail Avenue crossings and installation of medians to prevent vehicle drive-arounds. It also includes pedestrian crossing safety enhancement measures.


Maple Avenue Pedestrian Bridge: A pedestrian bridge will be constructed over the UPRR right-of-way at Maple Avenue.

Project Status

The Montebello Boulevard Grade Separation Project and the At-Grade Safety Improvements are in the final engineering and design phase. A construction contract is anticipated to be awarded in early winter 2021-2022 and construction is scheduled to begin late winter 2022 and be completed and opened to traffic by summer 2025. The Maple Avenue Pedestrian Bridge is at 35% design pending availability of construction phase funding. It is anticipated to begin construction in summer 2023 and be completed by summer 2025. The overall estimated project cost is $208.5 million.

Project Benefits

The project will eliminate crossing collisions, queuing and congestion, and reduce vehicle emissions. An average of 49 trains per day traverse Montebello and 10 collisions have been recorded at Montebello’s crossings, resulting in 3 fatalities and 2 injuries. 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.
