Canby-Marquam Hwy at Lone Elder Road intersection improvements


Project in right of way phase.

Updated: June 22, 2021

The intersection of Canby-Marquam Hwy and Lone Elder Rd is a T-intersection that is stop-controlled on Lone Elder Rd and uncontrolled along Canby-Marquam Hwy. The project will reconstruct the intersection and add a northbound left-turn lane. Congestion in the northbound direction on Canby-Marquam Hwy occurs in large part from vehicles waiting to turn left onto Lone Elder Road.


To reduce wait times on Canby-Marquam Highway at Lone Elder Road and create a safer intersection for all travelers.


  • The county hired Cardno (Engineers) to design the Canby-Marquam Highway project. The design phase began March 2020. The design is mostly complete. The project is now in right of way phase, continuing through spring 2022. Construction will likely begin summer 2022, during daytime hours. Construction is expected to be complete by fall 2022. 

Traffic impact

  • Rolling single lane closures and detours may be needed during construction.

Current activities

  • Completion of design and start of right of way planning work. 


  • Project estimate $1.1 million
  • Funding is provided from the Community Road Fund and Countywide Transportation System Development Charges.
