About
We have installed a pinned mesh system and repaved the road on NW Bridge Avenue (U.S. 30 Bypass) southeast of the St. Johns Bridge. This project removed hazardous vegetation, scaled loose rock and installed a pinned mesh system to reduce future rockfall events. Construction required a full closure of the southern section of NW Bridge Avenue for about four months.

What Problem Will This Improve?
This location has a history of known rockfalls, most recently in January 2022. This project extended the pinned mesh system installed after the 2022 rockfall event, pictured below. Pinned mesh systems are ODOT's standard mitigation tool to reduce the likelihood of rockfall events.
More information about the emergency repair is available on the project
