The new LED streetlights are dark sky compatible with a color temperature of 3,000-4,000 Kelvin, use 50% less energy than traditional highway and tunnel lights, and will reduce carbon emissions by approximately 3,500 metric tons per year. Improved streetlights line highways in Region 1 of the ODOT system, which includes Clackamas, Hood River, Multnomah counties, Eastern Washington and the Metro interstate bridges.

“From the start, we were thrilled to partner with Ameresco on a street lighting project that would reduce long-term maintenance costs and reinforce our commitment to reducing carbon emissions through renewable solutions. couldn’t foresee every challenge, but thanks to Ameresco, we successfully overcame obstacles as they arose and the project was delivered seamlessly and smoothly,” said Elizabeth Papadopoulos, Project Manager consultant, ODOT.

Ameresco worked in conjunction with ODOT to develop a plan that minimizes traffic and public safety issues while adhering to design standards led by ODOT. The Ameresco team also worked in coordination with the main freight stakeholder on the project, the Mobility Advisor Committee, to complete the streetlight conversion project within the construction time frame.

“Working with the Oregon Department of Transportation on this project has been extremely rewarding as the solutions implemented are sustainable and will provide benefits to commuters for years to come,” said Britta MacIntosh, senior vice president of Ameresco. “The LED lamps we’ve used come with lower color temperatures, which means they won’t need replacing for at least 15 to 20 years, a much longer life than the cycle traditional two to four year life of high pressure lamps.

Construction began in May 2020 and officially completed in December 2021.
