WELCOME TO TIMPANOGOS HIGHWAY
Timpanogos Highway (State Route 92) is the main east-west corridor for the communities of Alpine, Highland, Cedar Hills and northeast Lehi, as well as the primary access road for American Fork Canyon. Thousands of vehicles travel this corridor every day for a variety of reasons: for access to and from I-15, local travel or recreational purposes.
This area in northern Utah County is growing at a rapid pace. In order to improve mobility and accessibility, the Utah Department of Transportation (UDOT) is expanding Timpanogos Highway from I-15 to S.R. 74 (Alpine Highway) in Highland.
With this project, UDOT will do the following:
- Widen Timpanogos Highway to five lanes from I-15 to S.R. 74.
- Build "Commuter Lanes" from I-15 to Highland Boulevard. These lanes provide a direct connection to and from I-15 without stopping at traffic signals.
- Construct segments of multi-use trails to enhance the existing trail system in the area.
Once the project is complete, Timpanogos Highway users will experience:
- An improved commute to and from I-15
- Improved and safer access at local intersections
- An expanded trail system
This $148 million project is being constructed with a combination of federal and state funds.
Winter Driving Through Construction
Please remember with snow and ice on the road, slow down and give other cars extra space, especially through the construction zone. Give yourself additional time to arrive safely this winter.
Project Schedule Update
All eastbound and westbound lanes on Timpanogos Highway are now accessible to motorists during morning and evening commute times. Please be aware that intermittent lane restrictions and shifts are still expected at off-commute hours for at least the next two months.
We encourage you to stay actively engaged in the progress of the final stages of the project by signing up for weekly email updates and frequently visiting this website. You may also contact the project team at access@utah.gov and 877-222-3757.
The Timpanogos Highway project will bring a much-needed improvement over the previous roadway including more capacity, a smoother ride, better access to surrounding businesses and increased mobility options. With the addition of the DDI, not originally a part of the project, the interchange can now accommodate current and future traffic demands at I-15. Efficiency and commute times will also be improved with the commuter lanes, providing a no-stopping option for those traveling directly to and from I-15 from the eastern communities.
Thank you for your continued patience as we complete the project for your future convenience.
Ongoing activities
All eastbound and westbound lanes on Timpanogos Highway are now accessible to motorists during morning and evening commute times (unless otherwise noted in New Activities). Please be aware that intermittent lane restrictions and shifts are still expected at off-commute hours for at least the next two months as the contractor works to complete work items such as curb and gutter, sidewalks, barriers, striping and grading. Lane restrictions will be kept to a minimum but may be necessary to protect workers and allow space for construction equipment. Continue to watch for flaggers and remember the area remains a work zone and the posted speed limit is 45 mph.
