New Traffic Pattern on the North Side (Jeremy) 

Starting as early as October 5, there will be a new traffic pattern at the Jeremy Ranch interchange of I-80 on the north side (Jeremy) as crews shift traffic partially to the new roundabout.

When exiting westbound I-80, drivers will now be directed clockwise around the roundabout. The temporary road previously connecting the Jeremy side to the interchange will be closed and drivers can either make a left onto the new part of Jeremy Ranch Road to access the northern and western part of Jeremy Ranch, or continue around the circle to access either Homestead Road north of the roundabout, or Rasmussen Road eastbound towards the Jeremy Ranch Elementary School.

The Jeremy Store and businesses north of the interchange can be accessed on Homestead Road, north of the roundabout. See updated map, below.

Full detour map can be downloaded here.

Drivers should:

  • follow detour signage - do not use private roads to cut through
  • expect travel delays as drivers acclimate to the new configuration
  • use caution and watch for pedestrians / cyclists in the detour area

 Construction schedules are weather dependent and subject to change. 

North Side Detour 

As of Wednesday, July 31, there is a new traffic pattern and pedestrian/cyclist detour at the I-80 Jeremy Ranch interchange on the north side (Jeremy). This new detour is in addition to the south side (Pinebrook) detour that opened last month. 

Full detour map can be downloaded here

JR Phase 2B Detour

Drivers from the Jeremy Ranch side looking to access eastbound I-80, or the south side of the interchange (Fresh Market, Pinebrook, Quarry Village), need to use the new access road from Rasmussen Road and turn left onto the westbound I-80 on ramp before making a right onto Homestead Road. 

Drivers from the Pinebrook side looking to access westbound I-80 or the north side of the interchange (Jeremy Golf Course, The Jeremy Store), need to use the detour on the westbound I-80 on-ramp to reach the new access road before connecting to Rasmussen Road. 

This new traffic configuration will be in place through fall 2019. The project team has developed the detour plan in an effort to get the roundabouts operational as soon as possible. Implementing this now will help the team achieve that goal while minimizing flagging operations.

Pinebrook Detour

As of Wednesday, June 26, there is a new traffic pattern on the Pinebrook side of the Jeremy Ranch Interchange of I-80 to accommodate construction of the new roundabouts.

A new access road on the eastbound I-80 on ramp provides connection to and from the Pinebrook side of the interchange. Essentially, the on ramp has been turned into a two lane road during this detour phase.  

JRR Phase 2A Traffic Detour

Drivers headed to the south side of the Jeremy Ranch interchange (Fresh Market, Pinebrook, etc.) need to use the new access road on the eastbound I-80 on-ramp to access Quarry Village or Kilby Road.

Drivers from the Pinebrook side looking to access westbound I-80, or the north side of the interchange (The Jeremy Store, Jeremy Ranch Elementary, Jeremy Ranch Golf Course, etc.), need to use the detour to reach the new access road and turn left onto the eastbound I-80 ramp before making a right onto Homestead Road.

Jeremy Ranch Park & Ride Closed as of Monday, June 17 - PLAN AHEAD

The Jeremy Ranch Park & Ride is closed, as of Monday, June 17, to accommodate roundabout construction.

PC-SLC Connect Riders

Use Kimball Junction Transit Center as an alternate through Fall 2019.

Park City Transit - Pink 7

Services will now board at Quarry Village through Fall 2019.

Recycling Services

All recycling services will be re-routed to the Ecker Hill Park & Ride through Fall 2019.


Summit County, in coordination with UDOT, will build two new roundabouts at the I-80/Jeremy Ranch interchange. This project will optimize mobility and enhance safety for residents and commuters. Multiple studies found roundabouts to be the most effective long-term solution to address growth and traffic congestion at this interchange.

  • Two roundabouts
  • Bicycle and pedestrian improvements including:                                           - Grade-separated trail                                                                              - Underpasses at the westbound I-80 off-ramp, eastbound I-80 on             ramp and Kilby Road                                                                              - Pedestrian-activated warning lights and pedestrian refuges at the            Pinebrook Boulevard and Homestead Road crosswalks
  • Improved transit connectivity

    This project will improve the safety, mobility and reduce congestion at the I-80 Jeremy Ranch Interchange, located at Mile Post 141 along I-80, serves vital community and commercial interests in western Summit County. Severe morning and evening congestion impact travel of Summit County residents, visitors, and commuters. There have been multiple studies for this area including a study in June 2007, a follow up study dated June 2009, another in 2015, and several traffic signal warrant studies for the I-80 ramps. The alternatives evaluated in these interchange studies included, two different roundabout options (two large diameter roundabouts, and 4 smaller roundabouts), a Single Point Urban Interchange (SPUI), and two different signal options. At the time of the studies, the estimated cost for the roundabout option(s) were approximately is $10.3M; the SPUI option was $26.6M; and the two signal options were $22.1M and $21.8M respectively.

Based on cost and performance through the design year of 2050, the two large diameter roundabouts were selected as the preferred alternative.
