LAYTON — With Layton Improved construction resuming after a brief winter hiatus, the Utah Department of Transportation (UDOT) is advising motorists to be aware of traffic pattern changes in Layton around I-15 and the Hill Field Road interchange beginning Wednesday, Feb. 17, 2016.
The Hill Field Road project will move forward with the demolition of existing interchange bridges and construction of a new single-point urban interchange (SPUI). Workers will also finalize improvements to Hill Field Road. Crews will be working 24 hours a day, six days a week, to finish the project as quickly, efficiently, and as safely as possible while maintaining traffic movement through the area. All traffic lanes will remain open on I-15, and speed limits will not be reduced through the construction zone. Please stay alert and use caution as you drive through the area.
Beginning Wednesday, construction crews will shift I-15 traffic in the area onto a detour bridge on the west side of the interstate. Southbound traffic will shift onto the detour bridge on Wednesday morning, Feb. 17. Northbound traffic will make the shift on Thursday morning, Feb. 18. The traffic shift will be in place in both directions through mid-April.
Left turns on the off-ramps will be closed from now through July 2016, so motorists will need to follow the detour signs to turn right and travel through the ThrU Turns.
Trucking companies that normally use Hill Field Road to access businesses west of Layton should plan to use the Layton Parkway Interchange (Exit 330) or Antelope Drive (Exit 332) to access those businesses and industries through July.
Following the traffic shift, the section of Hill Field Road underneath I-15 will be closed on the evenings of Feb 20-21 so crews can demolish both bridges. It is suggested that motorists pay particular attention to signage that day for detour routes. The new SPUI bridges are being constructed offsite and will be moved into place through UDOT’s innovative accelerated bridge construction process. The northbound part of the bridge will slide into place in early March, and traffic will switch onto the northbound bridge in mid-April. Crews will then complete the southbound bridge and will slide it into place in April.
What to expect when it’s completed
- Four ThrU Turn intersections (already completed)
- Three additional lanes on Hill Field Road
- Wider bridges on I-15 over Hill Field Road
- A single-point urban interchange (SPUI) that will merge traffic at the off-ramps, controlled by one traffic signal.
Since the completion of the ThrU Turns, traffic flow has improved and delays reduced in the area. UDOT and Layton City are working together to tailor solutions that meet the city’s unique traffic challenges, and we’re excited to see the full project benefits realized when all the improvements are completed in fall 2016.
