Region 1 LED Replacement Pilot

Project Completed

Region 1: Portland metro and Hood River County (Various Cities, Clackamas, Hood River, Multnomah, Washington)

​​​​​​​​​​​​​​​ODOT is replacing over 8,000 roadway lights with LED lights on highways around Region 1, which includes Multnomah, Clackamas and Hood River Counties and eastern Washington County in 2020 and 2021


Traffic Impact

Most work will happen at night. Typical traffic impacts may include nighttime shoulder closures or short duration lane closures from 6 p.m. to 6 a.m. Monday through Friday nights. During lane closures, the section of a lane that is closed will move forward along with the construction crew as they replace lights one after another.​

Most work will not require detours, but there may be short-term, nighttime closures of single lane on-ramps and off-ramps.

Work in tunnels will have varied traffic impacts, including full tunnel closures for single lane tunnels, such as on-ramp or off-ramp tunnels. This website will have information about each tunnel closure before it happens.


NOVEMBER 2021: ​Light replacement began in 2020 and the project is now complete! Crews replaced over 8,000 road lights with new LEDs in in Region 1 in 2020 and 2021. 




This is a pilot project to convert over 8,000 roadway lights across Region 1 to light-emitting diode (LED) lights from the high-pressure sodium lighting currently in place. Converting to LED lights is estimated to save Region 1 about half of the current energy costs for lighting each year, or about $700,000 to $800,000 annually. Maintenance costs are also expected to go down.

Most high-pressure sodium lights need maintenance every two to four years, but the new LED fixtures will only need to be replaced every 15 to 20 years. The longer lifecycle for each LED fixture means less disruption to traffic flow during replacement and increased safety for maintenance crews who will spend less time each year replacing lights. The conversion to LED fixtures will also represent a carbon emissions reduction of 3,500 tons per year based on reduced power consumption.

This project is funded through an innovative contract with Ameresco which allows ODOT to pay for the replacement through future energy cost savings. This unique funding mechanism means that ODOT can pay for the project without taking money from other priorities.

LED Lights
Most of the new LED lights will have a color temperature of 3,000 Kelvin and will not shine any light above the fixtures. This lighting is considered dark sky friendly. Some select locations, including ODOT tunnels, will use 4,000 Kelvin fixtures. The majority of bicycle and pedestrian pathway lighting will use 2,700 Kelvin fixtures. ODOT is working with our Region 1 Historian to ensure the new LED fixtures maintain historical lighting where applicable while still meeting new requirements.

This project will replace most of the roadway lights on state highways in Region 1. Only about 10 percent of all the roadway lights in Region 1 belong to ODOT. The rest belong to city and county governments or private entities. Some lights on ODOT highways will not be replaced either because they are already LEDs or because we are planning on replacing them with an LED as part of another ODOT construction project coming soon.

Cost and Funding

ODOT is ​paying for this project using the future energy cost savings from converting to LED lights.


​This project improves lighting while reducing carbon emissions, energy costs and maintenance costs. It also increases safety for maintenance crews who will spend less time on busy ODOT roads replacing light fixtures.
