NW Cornelius Pass Road closed to through traffic between Highway 30 and NW Skyline on July 13.  The closure will be in place through September while the contractor completes safety improvements at two locations.

NW Logie Trail Road, a narrow and steep road to the north, is closed to through traffic during the closure of NW Cornelius Pass Road.

  • Hard Road Closure at NW 8th Ave.:  On July 20 the contractor will install barricades across Cornelius Pass Road near NW 8th Ave. in preparation for excavating a deep trench to replace a culvert under the road.  No vehicles will be able to pass this hard closure until late September.

  • Logie Trail Road closed to through traffic:  Logie Trail Road north of Cornelius Pass Road is closed to through traffic while Cornelius Pass Road is closed. The closure prevents cut-through traffic and large trucks from using this narrow, steep road.  

  • Other Road Work:  Highway 26 Vista Ridge Tunnel:  A contractor working for ODOT will close two of three lanes in the tunnel to install new LED lighting from 9 pm to 6 am Monday through Thursday nights from July 13 until August 7.  At least one lane will always be open in each direction in the tunnel.  There will be some night closures of ramps leading to the tunnel.  For Cornelius Pass users, this may impact detoured truck trips on weeknights.
