SR-12 Corridor – October 27, 2017


The two recent construction projects on the SR-12 corridor have reached substantial completion and work crews are currently finishing some miscellaneous tasks. We want to thank you for your patience through this construction season and wish you safe travels in the future!

Henrieville to MP 79.4 Pavement Rehabilitation

Improvements along SR-12 from milepost 29.2 – 58.5 and milepost 70.0 – 79.4 included a mill and overlay of new pavement, shoulder widening, repair and/or addition of guardrail and concrete barrier, cattle guard replacement, bridge repair, signage, and other miscellaneous safety improvements. Work crews are finishing the asphalt berm, and flaggers and construction personnel will be off-site by early next week.


US-89/SR-12 Intersection Improvements

Various safety improvements at the intersection of US-89 and SR-12 included:
* Northbound US-89 to eastbound SR-12 right turn lane upgrades.
* Installation a Rural Intersection Conflict Warning System (see figure to the right). As traffic approaches the intersection, various lights and marquee boards will be triggered to warn drivers of oncoming vehicles.
* Lengthening westbound SR-12 to northbound US-89 acceleration lane
* Installation of additional intersection safety lighting
* Adding left and right turn lanes into the Quality Inn located north of the intersection



UDOT would like to remind the public to be aware of work crews, lane shifts/closures, other drivers and pedestrians while traveling through all construction zones. Please slow down and obey all traffic signs. Zero Fatalities and zero injuries is a goal we can all live with.

Hours of operation

Maintaining traffic flow and minimizing construction impacts during peak travel times is a priority.

Project Overview

As part of UDOT’s routine maintenance program, three construction projects have been planned for this corridor. They are phased so as to minimize the impact to the traveling public, especially during the peak tourist season. A fourth project was added along the corridor as an emergency slope stabilization was required in response to a road slide at Bryce Canyon. The first phase of this slope stabilization is dcomplete and a second phase of this project is currently in the design phase.
