Traffic Plan and Detours

Learn more about the traffic plan.

NW Cornelius Pass Road is closed to all through traffic between Highway 30 and NW Germantown Road until late September 2019.

Access for local and emergency traffic and deliveries is permitted up to the hard road closure at 8th Ave. between NW Skyline Blvd. and Highway 30.  The road will be completely closed at 8th Ave. where the road will be excavated to replace a culvert.

There is also a hard road closure in Washington County where NW Cornelius Pass Road will be closed at NW Old Cornelius Pass Road.

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 should reopen by late September.  The contractor expects to work for several weeks after the road reopens in areas that will not require a closure of a traffic lane.
