May 2025 Update
Construction Impacts
Construction is now underway on 100 South and is planned to complete before the fall semester begins on August 17.
To maintain emergency access to the medical campus and hospitals, 100 South is limited to two eastbound (uphill) traffic lanes only. No westbound access on 100 South will be provided during construction.
Access to 1455 East, North Campus Drive, Federal Way and Central Campus Drive will remain open. However, because of the critical hospital access that 100 South provides, drivers not seeking medical care are encouraged to take an alternate route.
Anticipated Construction Activities:
Through the month of May, crews will remove the curb and gutter along the north side of 100 South and relocate or replace underground utilities.
Curb, gutter and sidewalk replacement on the north side is planned in late May or early June, with asphalt removal and paving planned in early to mid-June.
Pedestrian/Bicycle Notice:
Pedestrian access will be maintained on the south side of 100 South while crews reconstruct the north side through mid-June. Please follow the posted signage. North/south crossings are available at University Street and Wolcott Street. Cyclists should note that the traffic signal at Wolcott Street may not detect bicycles during construction, and they may need to use the pedestrian call button to activate the signal to cross north/south.
Detours
Medical Campus: Westbound traffic exiting the medical campus should use Mario Capecchi Drive or Wasatch Drive.
Academic Campus: Central Campus Drive will be accessible in both directions from North Campus Drive. It will also be accessible from Wasatch Drive to Exploration Way. Access from 100 South to lot 38/Northwest Garage will be maintained via 1455 East.
Local Streets: Side streets in the project area will be closed on the north side of 100 South. Federal Way will have access only to northbound (uphill) North Campus Drive. Adjacent neighbors should use local streets to access South Temple, University Street or Virginia Street.
What’s Changing on 100 South
New Multi-Use Path: Widen the south sidewalk between University Street and Wolcott Street to create a better path for people walking and biking, connecting to the existing path east of Wolcott.
HAWK Signal at Butler Avenue: Install a pedestrian-activated crossing signal to create a safer place to cross 100 South.
Better Access at Wolcott Street: Upgrade the crosswalk for ADA access across 100 South and add radar bike detection to sense people on bikes waiting at the intersection.
Pedestrian Safety Improvements at Wolcott/1455 East:
- Add a leading pedestrian interval so walkers get a head start before cars get a green light.
- Install flashing signs that activate when someone presses the pedestrian button, alerting drivers to people in the crosswalk.
New Sign at University Street: Add a “No Right Turn” sign for northbound drivers turning onto 100 South. It will light up when someone presses the pedestrian button.
Sidewalk and Parking Changes:
- Add new sidewalk on the north side of 100 South, east of Wolcott.
- Remove substandard on-street parking between University Street and Wolcott Street.
Painted Bike Markings: Add shared lane markings (“sharrows”) in the downhill direction to remind drivers to expect cyclists.
Frequently Asked Questions
Will the project make improvements to University Street in this area?
We are aware of the degraded pavement and narrow turn lane on University Street near 100 South and are working to identify when funding for that area will be available. This project does not extend into the University Street intersection nor onto North Campus Drive.
Why is a multi-use path being built instead of separate sidewalks and bike lanes?
There is not enough width on the road to accommodate a separate bike lane and two travel lanes are required to facilitate existing traffic and emergency response access to the medical facilities.
Was traffic calming considered along this route?
The project team considered traffic calming options for this section of 100 South. However, the types of traffic calming measures applicable to an emergency response route are limited. In addition, this short section of 100 South between University Street and North Campus Drive has multiple points that can help to slow motorists, including a 90 degree bend, two traffic signals, and will include two signalized pedestrian crossings when finished.
Why is the on-street parking being removed? Where will those cars now be expected to park?
The current on-street parking is not wide enough for a typical vehicle, meaning that parked vehicles
are taking up space in the travel lane. This is an unsafe condition that must be remedied. The University will identify alternative parking for the residences that typically use this on-street parking.
Will cyclists traveling downhill be directed to use the multi-use path or the road?
Cyclists travelling in either direction may use the travel lane or the multi-use path. The multi-use path is
recommended as a more comfortable, albeit slower, option.
Are there any plans to improve bus pickup and drop-off services along this road?
The project team has coordinated with the Utah Transit Authority (UTA) regarding bus stops along 100 South. UTA is planning to add a shelter to the bus stop near the North Campus Drive corner, which is a separate project and not necessarily on the timeline of this reconstruction project. The westbound bus stop near the intersection of University St will be relocated west of the intersection and improved as a
separate project on its own timeline.
Wasn't 100 South reconstructed a few years ago?
In summer 2021, Salt Lake City rebuilt 100 South to fix worn-out pavement, replace storm drains, and upgrade curbs and gutters. Sidewalks and driveways were repaired in select locations, and the street kept two lanes in each direction. The City also replaced parts of the water main and extended the life of the sewer line with a slip lining process.
Safer Streets for People Walking and Biking
- Bulb-outs were added at Lincoln Street (east side) and all corners of 1000 East and 1200 East to shorten crossings and slow turning vehicles.
- University Street intersection was fully redesigned with wider corners, new traffic signals, more trees and landscaping, and better lane alignment. Dedicated right-turn lanes were removed to reduce crash risk.
- McClelland Street crossing was improved with a raised median, trees, fresh paint, and a pedestrian button in the center island to boost visibility and safety.
