Repair work is beginning today on an eight mile segment of Utah State Route 143, the road from Parowan through the canyon to Brianhead. The highway suffered significant damage due to flooding in 2022.

Crews will be replacing four culvert pipes between Parowan and Brianhead between now and the end of the year. In January, work is scheduled to begin on damaged barrier walls. Of course, all of this is subject to weather conditions. Availability of materials could also factor in to the construction time.


In the winter months, Highway 143 is the only access point to the town Brianhead as Highway 148 through Cedar Breaks is typically closed for the winter, and winter conditions will often close Highway 143 from Panguitch Lake to Brianhead, and the section of the highway from Parowan is the only section typically open year round.

Sections of State Route 143 will be restricted to one lane use during the usual work hours of 7AM to 5PM Monday through Thursday. Construction work is not anticipated to be done on Friday or the weekends. A flagging operation will be in place during the construction period to provide alternating one way passage on the highway.
