Delays expected as UDOT begins construction on US-189 near Deer Creek Reservoir

UDOT shared that the project aims reduce congestion and increase safety for drivers. Once it is finished, US-189 will have two travel lanes in each direction from Provo to Heber City.

“This project is about making Provo Canyon safer and more reliable year-round,” UDOT Project Manager Craig Hancock said. “US-189 is a vital connection for both daily travel and recreation. Thousands of people use this route to reach work, the mountains, or the reservoir, and these improvements will help them get where they’re going more safely and with fewer delays.” 

UDOT shared that other key features being built with the project include:

• New traffic signal at the intersection of US-189 and SR-113
• Improved access and parking at the Island Beach Day Use Area, including longer acceleration and deceleration lanes and a new parking lot
• Better sight lines through the curved section along US-189
• New wildlife fencing to protect drivers and animals

US-189 will be reduced to one-way alternating traffic from 10 p.m. to 6 a.m. on weeknights and 11 p.m. to 8 a.m. on weekends between Rainbow Bay Day Use Area and 3600 South.

Construction will begin on Oct. 13. It is expected to conclude in fall 2027.
