Hayden Bridge is located in northeast Springfield, and carries Marcola Rd across the McKenzie River. Marcola Rd is the primary access to the Mohawk River valley. The Hayden Bridge Seismic Retrofit project added structural elements to the bridge to improve its resilience to earthquakes. Specifically, the project was designed for the bridge to survive and remain operational following a magnitude 9.0 Cascadia Subduction Zone event.
The project is funded by a FEMA Hazard Mitigation grant, awarded in 2023. An engineering firm (KPFF) completed the engineering design and environmental studies. The construction contract was awarded to Oregon State Bridge Construction. Construction was completed in April 2025.
