Alameda Corridor authority seeks bids for San Gabriel grade separation


Last week, the Alameda Corridor-East Construction Authority (ACE) invited 14 pre-qualified construction firms to submit bids for the San Gabriel Trench grade separation in San Gabriel, Calif. Bids are due May 2.

To be completed in about four years, the project calls for constructing a 1.4-mile-long, 65-foot-wide, 30-foot-deep, concrete-walled railroad trench and building street bridges at four grade crossings.

The $498.5 million project will involve lowering a 1.4-mile section of Union Pacific Railroad track in a trench running through the city of San Gabriel. The project will help ease local traffic congestion by grade separating four crossings with cumulative daily traffic of 89,740 vehicles, ACE officials said in a bid notice. The crossings are intermittently blocked by rail traffic, which averages 14 freight trains per day and six passenger trains per week.

The trench is the largest project in ACE’s ongoing program involving grade separations and traffic safety improvements in the San Gabriel Valley. Nearly 60 percent of the region’s container traffic travels along ACE’s corridor to destinations nationwide.
