Project Details

SW Terwilliger Blvd and SW Bertha Blvd on-ramps Maintenance Project

Construction Phase

Region 1: Portland metro and Hood River County (Portland)


​This June, we began maintenance work on the SW Terwilliger Blvd and SW Bertha Blvd elevated on-ramps to I-5 north. This work improves the weight capacity on the hinges of the ramps, which will maintain long-term safety and use of these heavily traveled on-ramps. ​​​

Trail impacts started mid-June 2019, prior to ramp construction,​ as crews begin setting up the work areas underneath the on-ramps.​

What You Can Expect Now: Trail Impacts

SW Trail 4​ is closed underneath the SW Terwilliger Blvd and SW Bertha Blvd on-ramps through construction. Trail impacts could last through this summer for the duration of the work. There are no expected impacts to the ramps or streets in the area at this time. We will update the project website and send an email alert when traffic impacts are known. 

A signed detour (below) is in place for the trail. The detour will take trail users onto surface streets to get around the closed area.

Traffic impacts will occur during summer construction. Sign up for future email alerts or check this site for traffic impacts.

About

​​This June, we began maintenance on the SW Terwilliger Blvd and SW Bertha Blvd elevated on-ramps to I-5 north. This work improves the weight capacity on the hinges of the ramps, which will maintain long-term safety and use of these heavily traveled on-ramps. Work includes removing and replacing existing bearings with new bearing pads.

Work is expected to be complete by fall 2019 but is subject to change based on weather and site conditions.

Why is maintenance needed on these ramps?

Due to the changing nature of vehicle weights, bridge load ratings need to increase to meet current design standards. In addition, the concrete compresses from use over time and needs maintenance. Bearing pads are replaced, and the new pads and hinges are re-encased and inserted closer inside the bridge for increased stability and load capacity.

What are the benefits of the project?

Newly replaced bearings will increase the load capacity of both on-ramps improving our roads and maintain long-term safety by ensuring the on-ramps can continue serving thousands of travelers a day.
