Drivers, plan on taking a little detour if you’re heading through downtown Truckee over the next two weeks.

State Highway 267 will be closed at the Truckee railway crossing from West River Street to Donner Pass Road Sept. 18 to 29.

Caltrans and Union Pacific Railroad plan to remove two of five sets of railroad tracks, insert pre-stress concrete and install state-of-the-art train warning assemblies.

Detour signs will be posted on Interstate 80 to the central Truckee exit and from Hwy. 267 to the roundabout via West River Street.

The project is part of the Federal 130 Grade Crossing Program, which allocates $5 million to California grade crossings state-wide for upgrade and repair. The project at Hwy. 267 will utilize approximately a fifth of California’s total grade crossing funds for this year.

“Pre-stress concrete will eliminate the frequency of frost-heaves or buckles, which should make the road smoother. You won’t believe the difference,” Ganyon said.

The pre-stress concrete is expected to last more than 30 years.

Union Pacific plans to upgrade their signals and signal controller, which will result in relocating the control box to the east side of Hwy. 267.

Wilkins said upgrades to the warning assemblies will likely include accommodations for new audible warning systems, such as the recently approved Wayside Horn System.
