OR 58 Seismic Landslide Mitigation

Construction Phase

Region 2: Willamette Valley and Northwest Oregon (Oakridge, Lane)

We're investigating the area to develop landslide mitigation options to keep the road open in the event of an earthquake.

Banner: Slow down, in the work zone it could save lives. Building a modern transportation system to help Oregon’s communities and economy thrive. During construction, Give yourself more time, try a new way or mode to get there or take a different route.

Pedestrians, including those with disabilities, will have access through or around work zones.

Pay attention in the work zone, slow down and move over – imagine this is where you work!

Always drive safely, watch for construction signs and workers.

Remember: fines double in all Oregon work zones, whether workers and signs are present or not.

Details

About

OR 58 is an important highway between the Cascade Mountains and the Willamette Valley. The west entrance to the Salt Creek Tunnel could be blocked during a large earthquake. The rocky slope above the highway could become unstable and block the tunnel entrance.

We're investigating the land and coming up with ideas to keep the tunnel safe and open for people to use.

This project will help get the road open quickly to emergency traffic and reduce the potential for people to be trapped inside the tunnel if a large earthquake occurs.
