I-80 Parley’s Canyon Drainage Improvement Project Wins Excellence in Concrete Award

Employee Focus, Preserve Infrastructure, by Guest Post.

Last summer’s Drainage Improvements project on Interstate 80 in Parleys Canyon was recently recognized with the Excellence in Concrete Award from the Intermountain Chapter of the American Concrete Institute. The award recognized the team of UDOT, H.W. Lochner, W.W. Clyde and its subcontractors, and Geneva Pipe and Precast for designing, casting, and installing the new culvert adjacent to I-80. This drainage project, which was completed in fall 2013, installed more than 10,500 feet of 66-inch reinforced concrete pipe along a two-mile segment of I-80 near the mouth of Parleys Canyon. Crews also installed 6,700 linear feet of median and lateral drains, along with 80 concrete box structures. The new drainage system, with a 100-year design life, replaces the original corrugated metal pipe that was installed prior to construction of I-80 in the 1960s.

As many of the pipe sections are fabricated with slight differences to accommodate elevation changes or curves in the two mile-long culvert, each section had to be placed in exactly the right spot. The pipe included beveled segments, where the spigot end of the pipe had a slight bevel to the left or right, as well as straight segments. These segments allowed the pipe to bend gradually to match the grade and curves of the roadway. To install each segment, an on-site surveyor took measurements to ensure both vertical and horizontal alignment.

Significant challenges faced by the project team included maintenance of traffic – 45,000 cars each day traveled through the work zone – and the solid rock of the canyon, which required blasting in several locations merely feet away from the edge of pavement. In total, 10 separate blasts were carried out, for a total of more than 2,200 linear feet. The project was completed under the $11.8M budget just in time to suit the unique weather and stream flow conditions in the canyon.

According to the ACI Intermountain Chapter, the ACI Excellence in Concrete Awards “recognizes the innovative and aesthetic uses of concrete by owners, architects, engineers, contractors and ready mix producers.” This award is the latest recognition of the combined efforts of UDOT and the contractor team to meet challenges and complete a quality project that will benefit Utahans for years to come.

  1. These new pipes are very much needed to drain the excess water as well as the canyon runoff so congratulations to Lochner, Clyde, and the rest of the team for this recognition!
