Construction and Traffic Impacts

Plan ahead for construction to start in 2026

Construction on a large project like this happens in stages. Since we don't have a contractor on board yet, we don't know the exact order or timing for each stage of construction. Impacts and other details may change. Make sure you're signed up to get emails from us – we'll share updates when we know more details.

To change this intersection, we'll need to close Perrydale Road to the south of OR 22.

You can expect: 

  • Perrydale Road south of OR 22 to temporarily close.
  • To detour around the closure using Kings Valley Highway.
  • Construction noise and delays.​
  • Local access only on Perrydale Road from OR 223 during the road closure.

To realign Smithfield Road and Coville Road, we'll need to temporarily close Kings Valley Highway, Smithfield Road and Coville Road at the intersection.

You can expect: 

  • Kings Valley Highway to temporarily close at the OR 22 intersection.​
  • Smithfield Road to close at the OR 22 intersection. 
  • Coville Road to close at the Smithfield Road intersection.
  • Traffic to detour around the road closures using Perrydale Road. Frieght traffic can use Dyck Road and Perrydale Road. 
  • OR 22 lane closures with flaggers directing traffic as needed.
  • Construction noise and delays.
  • Local access only to NE Kings Valley Highway from OR 223 and to Coville Road from OR 99W during the road closures.

To help reduce impacts, we are paving the shoulder north of OR 22 to have room to shift both directions of traffic away from the roundabout construction.

  • Kings Valley Highway to remain closed at the OR 22 intersection.​
  • Smithfield Road to remain closed at the OR 22 intersection. 
  • Coville Road to remain closed at the Smithfield Road intersection.
  • Traffic to detour around the road closures using Perrydale Road. Frieght traffic can use Dyck Road and Perrydale Road. 
  • Construction noise and delays.
  • Local access only to NE Kings Valley Highway from OR 223 and to Coville Road from OR 99W during the road closures.

During this stage of construction, traffic will shift to the temporary diversion road while we work on the roundabout.

You can expect:

  • OR 22 traffic to shift to the temporary diversion road. 
  • Construction to continue on Smithfield Road and Coville Road.
  • Kings Valley Highway to remain closed at the OR 22 intersection.​
  • Smithfield Road to remain closed at the OR 22 intersection. 
  • Coville Road to remain closed at the Smithfield Road intersection.
  • Traffic to detour around the road closures using Perrydale Road. Frieght traffic can use Dyck Road and Perrydale Road. 
  • Construction noise and delays. 
  • Local access only to NE Kings Valley Highway from OR 223 and to Coville Road from OR 99W during the road closures.​

After we've built the majority of the roundabout, traffic will start using it as we build the Smithfield Road connection to the roundabout.

You can expect:

  • Smithfield Road to reamin closed at the OR 22 intersection. 
  • Coville Road to remain closed at the Smithfield Road intersection.
  • Traffic to detour around the road closures using Perrydale Road. Frieght traffic can use Dyck Road and Perrydale Road. 
  • Construction noise and delays.
