SR-143 Parowan Canyon Safety Project
A Utah Department of Transportation (UDOT) road construction contractor has completed flood repair work on an eight-mile segment of State Route 143 in Parowan Canyon. Crews replaced multiple culvert pipes and repaired and replaced damaged barrier walls between Parowan and Brian Head during the 2024 and 2025 construction seasons. This project repaired damage caused by flooding in 2022 and improved drainage for the corridor.
The public is encouraged to visit the UDOT Traffic website or app at udottraffic.utah.gov for current traffic information.
