Night Paving in American Fork Canyon

Construction on American Fork Canyon (SR-92 and SR-144) consisted of 1.5” to 3” mill and overlay over 11.4 miles using both HMA and SMA mixes. Most of the work was done at night while maintaining one open lane throughout the duration of the project. A new foundation was constructed in a new location for the fee booth at the mouth of American Fork Canyon. The majority of the canyon road was widened by 2-4 feet improving the safety of motorists and cyclists.

American Fork Canyon is a very popular recreation area for Utah County. The popularity of the canyon was exacerbated by the COVID-19 pandemic with a visitorship increase eight times the normal during the summer months throughout construction. Maintaining a safe work zone, proper flow of traffic, a happy public, and a serviceable road required coordination of efforts between Geneva Rock, UDOT, Horrocks Engineers, National Parks Service (Timpanogos Cave), Lehi and American Fork Irrigation Companies, and the U.S. Forest Service. The project team successfully negotiated the challenges of maintaining issues encountered on the project and dealing with a populous more focused on spending time outdoors.
