UPR has spent millions of dollars to repair and replace portions of the railroad bridge over Tempe Town Lake. Repairs were also made to portions of Rio Salado Parkway and damage to Tempe Beach Park.

About the incident

At approximately 6 a.m. on Wednesday, July 29, 2020, a cargo train derailed on the historic Union Pacific train bridge that crosses Tempe Town Lake. Union Pacific owns the railroad bridge over Tempe Town Lake.

Crews from four area cities responded to help put out the ensuing fire and remove hazardous materials from the area. 

City officials said there were 12 train cars affected by the incident. Two of them contained Cyclohexanone, a chemical used to make nylon, paint remover, wood stains and insecticides. None of these chemicals entered Town Lake, officials said.

The Arizona Department of Environmental Quality has spent more than $100,000 in tests and determined that no additional cleanup is needed at this time under the rail bridge. Officials said precautionary testing will continue to ensure the lake is safe.

Historic Bridge

The railroad bridge was built in 1912 and began operations in 1915. It is part of a rail line that starts on the West Coast and goes as far east as Chicago and New Orleans. Portions of the damaged bridge were preserved and given to the Tempe History Museum.

Tempe does not own the railroad bridge. Since 1887, the federal government has had authority over the movement of passengers and property by rail as well as rail infrastructure.
