SR-12 Corridor – March 21, 2018

Bypass construction


Red Canyon Tunnels Rehabilitation

The bypass road around the tunnels is currently being constructed. During construction, the bike path will be closed through the work zone. Once the bypass road is complete and operational, the bike path will reopen. At the point where the path connects with the bypass road, bicycles and vehicles will share the bypass road for about a half mile. Bicycle traffic will then stay on the dedicated path while vehicle traffic will merge back on to SR-12.

Drivers and bicyclists are urged to be courteous and aware of each other when sharing lanes.

MP 0 – MP 30 Safety Improvements

Mobile signals like the one to the right will be seen on SR-12 between MP 17 – MP 23. These signals are directing traffic around work crews installing new guardrail in various places along the highway to enhance driver safety. Additionally, crews are installing new signs along the corridor and will utilize flaggers and/or mobile signals as needed to ensure the safety of the traveling public and the construction crews.

Guardrail Install


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.

Project Overview

​SR-12 is designated a Scenic Byway and an All-American Road. It is a gateway connection to many parks and recreational areas that include: Bryce Canyon National Park, Capitol Reef National Park, Grand Staircase-Escalante National Monument, Red Canyon, Kodachrome Basin State Park, Escalante Petrified Forest State Park, Anasazi State Park, and Hole in the Rock.

As part of UDOT’s routine maintenance program, various 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
