| PROJECT DESCRIPTION | |
The 2.2-mile San Gabriel Trench grade separation project will result in the lowering of a 1.4-mile section of Union Pacific railroad track in a trench through the City of San Gabriel with bridges constructed at Ramona Street, Mission Road, Del Mar Avenue and San Gabriel Boulevard, allowing vehicles and pedestrians to pass over the tracks. The rail line will return to grade east of San Gabriel Boulevard, which would need to be raised less than 2 feet due to track elevation. The rail crossing at Walnut Grove Avenue will remain at-grade and may require a shallow lowering of the roadway to match the proposed railroad grade. |

| PROJECT IMPACTS | |
Project construction will create 8,964 full-time equivalent jobs. The project will reduce locomotive horn and crossing bell noise, congestion and air pollution, estimated at 213 tons/year of air toxins and greenhouse emissions by 2030. The project will eliminate an estimated 1,744 hours of vehicle delay each day at four crossings, the busiest of which, San Gabriel Blvd., carries 35,310 vehicles per day and operates at 118% of capacity in peak hours. Four crossing collisions have been recorded over the last 10 years, with two motorists killed and two injured. The project will eliminate delays for emergency responders and the potential for crossing collisions, estimated at one every four years. Temporary and alternating closures of Ramona Street, Mission Road, Del Mar Avenue will be required during construction; one lane in each direction of San Gabriel Boulevard will remain open. Advance notice of closures, detours and other construction impacts will be provided. |
