The Oregon Department of
Transportation is working on a project to increase the stability of the
hillside and traffic safety of Oregon Highway 99E in Oregon City. We
are currently designing the project. Construction is planned to begin summer 2018.
Why is this project taking place?
In Oregon City, the steep hillside next to Oregon Highway 99E has a history of rockfalls. This project will increase safety by reducing
the potential for rocks falling and to impacting the highway and travelers.
Work will occur on three sections of the hillside. The project area stretches from Mile Point
12.62-14.06, which is from the south side of the tunnel at Railroad Avenue
through Canemah Park. The hillsides in this area have a history of rocks
falling from the slopes and closing the highway. We previously installed wire mesh on the hillsides to help control the rockfalls in the 1980s, 1995 and 2003.

*Please note: The above map is for informational purposes only. The information is subject to change.
What is the solution?
The existing wire mesh needs to be moved or removed and the hillsides need to be scaled,
which removes loose rocks from the slopes. The slopes were last
scaled entirely when the mesh barriers were installed. The contractor will also insert
any rock bolts needed to stabilize the slope and reinstall the wire mesh or replace any wire mesh that is damaged.
What are the traffic impacts?
During construction in summer 2018, there will
be 24-hour lane closures everyday on OR 99E. We are working to minimize the time
needed for repairs and traffic impacts, but do not yet know how long each section will take to secure. Those driving should
expect delays or plan an alternate route during work.
We expect to have more
information about traffic impacts by summer 2017.

Other work in the area?
- The City of Oregon City is
replacing an exposed waterline on the hillside stretch near the tunnel (Section 1). The
pipe previously had several repairs, but has now reached the end of its
useful life. Oregon City plans to replace the pipe during summer 2017. Waiting
until ODOT’s project in 2018 would mean risking the pipe leaking during another
winter season. For questions about this waterline replacement, contact Oregon City or visit their project page.
- ODOT is also planning an illumination project in Oregon City at the railroad tunnel and pedestrian tunnel (next to Section 1) that will increase visibility in both tunnels and reduce maintenance costs. The roadway and pedestrian tunnels have obsolete fixtures and electrical systems that need to be updated. A proposed element of the project is to install a variable message sign south of the tunnel on a new cantilever sign structure. We are planning to make improvements to the lighting in 2018. More information will be provided as it is available.
