I-15 Choke Point Auxiliary Lanes

April 5, 2017



The I-15 Choke Point project consisted of adding an auxiliary lane on southbound I-15 from Layton Parkway to 200 North in Kaysville, and an auxiliary lane northbound I-15 from the Kaysville rest area to Layton Parkway. This particular section of I-15 is extremely congested and is considered a very high risk area of work due to the limited amount of traffic visibility to the construction zones – especially in the southbound section.
The original timeline for the project had a schedule of 80 days to complete. One of the major portions of the work was the southbound widening which included the reconstruction of the MSE wall with integrated storm drain along the UTA and UP track lines. Along with this scope of work, median storm drainage work was also required in the southbound direction. This area played an integral role in the scheduling and constructability due to the limited amount of traffic control that was allowed on the project. In addition to the traffic control, UTA had their own set of constructability time frames and regulations that were required.
Overall with the limited amount of traffic control and lanes needed for safety in such a high risk area, finishing the project on time with zero accidents was a significant achievement.
  • Runway and Taxiway Pavement Rehabilitation

     Salt Lake City Department of Airports required upgrade and a pavement rehabilitation on several of their runways (16-34). Taxiway ‘A’ was reconstructed, then milled and paving was completed on the runways and taxiway.

  • I-80; Silver Creek to Wanship

    Innovation, technology and environmental consciousness are of the highest importance at Geneva Rock. These were vital standards during the I-80 Silver Creek to Wanship project that was recently completed. UDOT teamed up with Geneva Rock to replace this 7 1/2 mile stretch of I-80 that had corroded due to the high altitude and harsh environment.

  • Lehi City Waste Ditch Improvements

    The city of Lehi, Utah sought to increase the allowable amount of water their municipal drainage ditch could handle. The Lehi City Wast Ditch Improvements project includes removal of  four existing pipe culverts, replacing them with pour-in-place box culverts.  Utilities and asphalt paving work is also being completed at the end of the project to improve the surrounding areas. Geneva
