2025 Provo Canyon Barrier Safety Project Overview

This project was the second phase of an ongoing effort to improve safety along US-189 in Provo Canyon. Work items included replacing the existing median barrier with improved 42-inch concrete barrier between the north and south travel lanes as well as making drainage improvements.

  • Median barriers help prevent vehicles from crossing over into oncoming traffic, significantly reducing, if not eliminating, the risk of head-on collisions.

  • Crash cushions are installed at the end sections of the barrier as a buffer zone in the case of an accident to help gradually decelerate a vehicle and reduce the force of an impact with a fixed object like the median barrier, ultimately minimizing the severity of injury. See the example below.

      

  • Drainage improvements included installing drains along the median barrier to catch runoff water and direct it away from the road surface. The drain pipes were rehabilitated to improve their efficiency.
