Traffic Detour Starting Wednesday, June 26 - PLAN AHEAD

Starting Wednesday, June 26, there will be 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 will provide connection to and from the Pinebrook side of the interchange. Essentially, the on ramp is being 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.) will 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.), will 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.

This new traffic configuration will be in place through August 2019. The project team has developed the detour plan in an effort to get the roundabouts operational by the time school is back in session. Implementing this now will help the team achieve that goal while minimizing flagging operations.

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.

Overview

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.

Improvements
  • 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.
