San Bernardino County Transit Authority (SBCTA) Monte Vista Avenue/Union Pacific Railroad (UPRR) Grade Separation Project
SBCTA, in cooperation with the City of Montclair and UPRR, is leading the construction effort on the new Monte Vista Avenue/UPRR Grade Separation project. This project will construct a grade separation over the UPRR tracks along Monte Vista Avenue. The project improves safety and rail operations, as it will remove the existing at-grade crossing between vehicular, pedestrian, and rail traffic.
PROJECT DETAILS:Value: Overall Project $24.1M
Location: City of Montclair, San Bernardino County, California
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.
G3 Quality has been delivering quality control management for hot mix asphalt (HMA) materials placed at the project since construction began in 2018. Our scope covers quality control inspection, sampling, and testing services on the project. Major features of the project include elevating Monte Vista Avenue over three sets of UPRR tracks and State Street. Structural elements consist of a 300-foot, two-span, concrete wide-flanged girder bridge with mechanically stabilized earth (MSE) walls.
OUR ADDED VALUE
Our contributing values to this project include our well-recognized SBCTA and Caltrans experience, demonstrated ability to successfully manage complex construction schedules (including night and weekend shifts), and collaboration with project construction, engineering, and program management entities – all to ensure quality materials and practices are implemented to successfully complete this important regional rail bridge project.
