Project Description

This five-mile stretch of NW Cornelius Pass Road has seen a high rate of crashes in recent years, including fatal crashes and truck spills. Increased traffic, high speeds and the rugged terrain all play a part in the high number of crashes.

This project will include safety improvements such as:

  • curve realignment
  • shoulder widening and rehabilitation
  • signage and sight distance improvements
  • vehicle pullouts
  • guardrail upgrades


Construction began with a road closure to through traffic on July 22, 2019. The road will reopen in mid-October.  Some work items will be completed in summer 2020.
