Houghton Road Bridge Over Union Pacific Railroad Dirt Haul and Asphalt Removal

Motorists on Houghton Road south of Mary Ann Cleveland Way/Old Vail Road are urged to use caution when traveling this section of roadway as trucks continue to haul material to the job site to construct the new bridge approaches at Houghton Road and the Union Pacific Railroad (UPRR). Pulice Construction, under contract with the City of Tucson Department of Transportation (TDOT), is building two new bridges over the UPRR.

Large trucks are delivering material to the east side of the existing bridge from Old Vail Road and from Valencia Road. The dirt haul is taking place from approximately 8 p.m. to 6 a.m., Monday through Thursday. Material is being placed on both the north side and the south side of the railroad tracks. When trucks haul material to the south side of the railroad tracks they will head southbound over the existing bridge and exit on the west side of Houghton Road. Truck speeds over the bridge will be limited to 10 mph and motorists are being urged to use extreme caution when following a truck as it exits Houghton Road. This work is scheduled to be complete by mid June 2017.

Also, beginning on Monday, May 1, 2017, the taper and right turn lane on northbound Houghton Road just south of Old Vail Road will be closed for work on the east side of Houghton Road.

The Houghton Road Widening project from Mary Ann Cleveland Way to the UPRR will increase bridge capacity over the railroad and will accommodate three lanes of traffic, as well as bike lanes and sidewalks in each direction. The bridge project will be constructed in two phases and is scheduled to be complete in summer 2018. This is part of the overall Regional Transportation Authority (RTA) Plan to improve Houghton Road from Tanque Verde Road to Interstate 10.

The first phase of construction will keep both northbound and southbound traffic on the existing Houghton Road two-lane bridge, while the new three-lane bridge is constructed to the east of the existing bridge. Once the new bridge is complete, northbound and southbound traffic will be shifted to the new bridge. The second phase will include demolishing the existing two-lane bridge and building a three-lane bridge where the old bridge was located. During construction, at least one lane of travel will be maintained in each direction.

This project is federally funded along with major contributions from the Regional Transportation Authority (RTA) and Pima County. The project is part of the $2.1 billion RTA plan, which will be implemented through 2026. The multimodal plan, nearly halfway through implementation, includes roadway, safety, transit, environmental and economic vitality improvements.
