Grade Separation: Ramona Avenue, Montclair
San Bernardino Associated Governments and the City of Montclair worked cooperatively to build a bridge (also known as a grade separation) over the Union Pacific railroad tracks at Ramona Avenue, between Mission Boulevard and Brooks Street in Montclair.
The City of Montclair completed the detailed design of the grade separation and acquired needed right-of-way. SANBAG lead the construction, which began in September 2008 and was completed in May 2010.
The project built a four-lane bridge over the Union Pacific railroad tracks, which cross at Ramona Avenue. This eliminates the lengthy waits for trains, and improves safety and air quality.
The new bridge provides two travel lanes and a left turn pocket in each direction, a striped median and a pedestrian sidewalk on either sides of the bridge. During construction, new streets were constructed and minor realignments of existing streets also occurred to help ease the traffic congestion in this area.
During the construction project, the Ramona Avenue and State Street intersection was fully closed to all motorists to speed up construction.
The project cost about $20 million, with funding provided by the state’s Traffic Congestion Relief Program, federal funds and city funds.
