Construction Update

September 21, 2018 - Weekly Roadway Construction Update

Work on the south side of the street is underway. One-way traffic remains in the east-to-west direction.
  • Crews are removing curb, gutter, and sidewalk on the south side of the street, beginning on Gold Dust, heading west
  • Following the removals, crews will form and pour the concrete for the new curb and gutter
  • Electrical conduit is being placed underground, along with junction boxes for new lighting along the corridor
  • Waterline work continues in the roadway. The travel lane may be adjusted according to the daily activities, however, it will always be marked with traffic cones
Note: The light poles will be removed from the south side of the street. For the next month, all street lighting will be removed from Prospector Avenue. Please use caution when traveling at night, particularly regarding the one-way traffic.

For the safety of motorists, pedestrians, and the various construction crews in the area, the speed limit has been reduced to 25 mph on Prospector Avenue. Please be mindful of your surroundings and proceed through the corridor with caution and awareness.

Park City Police will be patrolling the area to enforce the one-way traffic operations. Violators will be fined.


Prospector Avenue traffic will be open to one-way travel only, heading westbound.
Prospector Ave can be accessed from Sidewinder and Poison Creek, but vehicles will not be able to enter Prospector Ave from Bonanza. This configuration will be in place through the full length of the project. A map below provides detail regarding the direction of travel during construction. 

Prospector Square Update:

The Prospector Square Property Owner’s Association is making improvements to Lots D and H. This work is being performed and managed by separate contractors and entities from the Prospector Avenue improvements, however, representatives from both projects are in close coordination with one another. Current activities include:

Beginning Thursday, Aug. 30, work will resume in Lot H (Good Karma) with additional concrete forms followed by the pouring of concrete over the next few days. In addition, we hope some work will commence next to the New Claim Condos in Lot D. Paving in Lot H is expected to begin in the next two to three weeks. The contractor must let the entrance concrete cure before their heavy trucks bring asphalt into the lot. The project is behind schedule, overall, due to multiple factors but all sewer work will be completed early next week. With the exception of landscaping, work in Lot H will by substantially complete by the end of September.

One side benefit in Lot H was completed this week — Cache Valley Electric laid fiber optic cable for All West Communications.

Final landscaping curbing is complete near Picabo Academy. A major concrete failure was also fixed in the Lot D garage earlier this week. 

There will be no work done on Saturday, Sunday and Monday due to the Labor Day holiday. Work will recommence on Tuesday.

Project Overview

Park City Municipal Corporation in coordination with the Utah Department of Transportation is improving Prospector Avenue between Bonanza Drive and Sidewinder Drive. The project will enhance and promote alternative multi-modal transportation uses and address roadway infrastructure needs by:  
  • Creating a safe environment for all modes of travel
  • Reducing vehicular speeds by introducing a "complete street" cross section
  • Defining more efficient use of existing space by better marking travel lanes and bus pullouts
  • Upgrading the street lighting with LED fixtures
  • Improving the roadway drainage
  • Resurfacing the asphalt pavement

The project team is working closely with the Prospector Square Property Owners Association to coordinate with their recently completed Master Plan.
