Molalla River (Knights Bridge Road) Bridge Repairs

The Molalla River (Knights Bridge Road) Bridge in the Canby area is an important connection for delivery of goods and services throughout the region. Bridge repairs will include painting, sealing cracks on the deck, resurfacing the deck, and repairing the concrete columns and bridge approaches. This project also includes seismic upgrades. 

Status

Design phase

Updated: Dec. 21, 2023

Why

To preserve and extend the life of the bridge, to remove weight restrictions, allow for traffic to cross in an emergency, and to improve resiliency within our essential transportation network in the event of an earthquake.

Schedule

The schedule has been delayed by one year due to environmental permitting requirements and scheduling conflicts. 

  • Design: May 2022 to March 2023
  • Right of way: April 2023 to Spring 2024
  • Construction: Summer 2025 to Summer 2026

Traffic impacts

Single-lane closures will be needed during inspection and design phase. A four-month full road closure on N Knights Bridge Road at the bridge site is anticipated to pave the deck and perform bridge repairs. 

Current activities

Design by Consor/Quincey Engineering has progressed to 60% and is awaiting review by environmental agencies for permit applications. Project advertising is anticipated to be bid in Oct. 2023. 

Funding

  • Project estimate $5.4 million
  • Funding is provided from ODOT Local Bridge Program with a 10.3% match from County Road Funds
