Here are details right from the Clackamas County website:

Project Description: Replace the existing one-lane bridge with a new two-lane bridge. The current bridge, built in 1958, is reaching the end of its functional life and is weight-limited.  The 18-month construction  project includes building a temporary detour bridge, removing the old bridge, building the new bridge and then removing the detour bridge.

Things to be aware of:

  • Trees are being removed early to avoid any conflicts with nesting birds.
  • Work in the water is limited by law to strict time periods (known as the “in-water work window”), generally 6 weeks during the summer
  • There may be delays of up to 20 minutes, but no complete closure is scheduled.  If there is a need for a closure of longer than 20 minutes, area residents will be notified at least 24 hours in advance and accommodations will be made for emergency vehicles, as needed.

  • The bridge is a critical life line for residents, as this is the sole access to several homes
  • The bridge is considered structurally deficient and functionally obsolete.
  • The bridge has three spans (100-foot steel pony truss and two timber approach spans).
