Construction Impacts

Night Work
Nighttime and some daytime construction activities will occur at each site location. Construction will begin on I-5 first, and then on I-84. As the project progresses, work will take place on both highways at the same time.​​

Nighttime construction noise will occur intermittently at specific site locations on I-5 and I-84 and those working or living in the area may hear the noise. 

Noise will come from heavy equipment, construction trucks, beeping when construction vehicles are in reverse (a requirement by the Occupational Safety and Health Administration), and equipment such as concrete saws, drills and haul trucks. Work is expected to be completed at most sites within two and six nights. However, other sites will take longer to complete.

Nighttime lane restrictions on I-5 will occur weekdays from 8 p.m. to 5:30 a.m. and weekends from 8 p.m. to 9 a.m. Nighttime lane restrictions on I-84 will occur weekdays from 10 p.m. to 5 a.m. and weekends from 11 p.m. to 8 a.m.​

Working at night is necessary to keep daytime traffic flowing on these heavily traveled freeway. 

For noise-related questions or concerns during construction, call the 24-hour noise hotline at (503) 412-2361.


​Construction: Currently underway through Fall 2018
*Schedule is subject to change based on weather and site conditions. ​



The Oregon Department of Transportation is working on Interstate 5 and Interstate 84​ in 2018 to ins​tall, replace, repair and upgrade existing interstate signs and sign structures to meet current federal standards. 
The project area along I-5 will occur south of the Iowa Street viaduct and north of the OR Highway 217 interchange. The project area along I-84 will occur between the NE 102nd Ave. overcrossing and slightly east of the NE 148th Ave. overcrossing. 

Project information for the I-84 Sign Replacement Project is available at

In 2015, ODOT replaced several green highway signs along Interstate 5 in Portland. ​

Cost and Funding



​Coral Construction


The new signs will feature more reflective materials and a less cluttered design, making them easier to read. 

What Problem Will This Improve?

Several existing interstate signs and sign structures on I-5 and I-84 are in poor condition and need to be replaced, repaired or upgraded to meet current federal highway standards.
