About
I-84 is a major route from Portland to eastern Oregon and Idaho. It is heavily traveled year-round. It is part of the national highway system and is also a designated freight and vertical clearance route.
Many signs along I-84 and I-82 are faded and have lost reflectivity. They are difficult to see and read, especially at night or during other low light conditions.
Project elements include:
- We will replace all mainline and ramp signs in poor condition.
- Mileposts and traveler information signs (blue signs with restaurants, gas and other services) will not be replaced. Some blue rest area signs will be replaced, depending on their location and condition.
- Ground-mounted signs will receive new sign supports.
- Cantilever structures (like the one at 180 eastbound) and bridge structures (like the one at Exit 179 and 180 westbound) will remain.
- Some signs may be removed from undercrossing structures to ground-mounted supports to reduce future maintenance costs.
