I-205 Abernethy Bridge Project

Construction Phase

Region 1: Portland metro and Hood River County (Oregon City, West Linn, Clackamas)

The I-205 Abernethy Bridge Project provides Oregonians with safer, more reliable travel to access work and critical services, even after an earthquake or other major disaster. The project includes upgrading the Abernethy Bridge to withstand a major earthquake, improving on- and off-ramps near the bridge, and making improvements to local bike and pedestrian routes.

Construction Impacts

The I-205 Improvements Project is focused on seismic improvements to the Abernethy Bridge, which spans the Willamette River between Oregon City and West Linn, and safety improvements to the surrounding area.

Construction to improve and widen the Abernethy Bridge in 2022. We expect to finish construction in 2025 and implement a bridge toll to help repay roughly half of the construction cost — pending environmental review and federal approval. The other half will be paid for with transportation funds raised statewide.
