Roadway LED Light Replacement, Oregon

closed

The Oregon Department of Transportation (ODOT) is replacing over 8,000 roadway high-pressure sodium lights with light-emitting diode (LED) lights on Region 1 highways. This includes the Portland metro and Hood River County areas, and various cities including Clackamas, Hood River, Multnomah, and Washington. The project aims to reduce electricity and maintenance costs, improve light quality, enhance safety, and help meet the State's carbon-reduction goals. To minimize the impact on traffic, ODOT will perform most of the work at night. Most lane closures will be short, but longer lane closures or full closures will be required to replace the lights and control systems in tunnels. During the project, ODOT will recycle lighting and removed materials, while matching or maintaining existing fixtures. Each fixture is expected to take about 20 minutes to replace, and in most cases, crews will turn off several lights in a row and move a lift truck from one light pole to the next as fixtures are replaced. To avoid nighttime vision issues with bright white lights, ODOT chose to use 3,000 K fixtures on exterior roadways. This burn temperature has a warmer look that is considered “dark-sky friendly.” The new LED lights come as one electrical unit and last longer than high-pressure sodium lights, so they will help reduce overall maintenance costs.
