Union Pacific’s I-5 corridor route to be closed until at least Sept. 1

Union Pacific’s main line linking the Pacific Northwest and California — its Interstate 5 corridor — is likely to remain closed until at least Sept. 1 as a result of the wildfire that destroyed the massive Dry Canyon Bridge in Northern California along with 9 miles of right-of-way.

Instead, UP Engineering Department employees and an army of contractors rebuilt the bridge in 34 days, allowing trains to resume rolling on Aug. 1...

They had to build roads to the floor of the canyon so three massive cranes could be set up. Only one of the bridge’s 19 spans escaped damage, so crews installed nine new spans and heat-straightened another nine to repair warping caused by the fire. Ballast deck pans were added, along with 700 new ties and new rail. Some 58 tons of new steel were used to rebuild the bridge...
