The Washington State Department of Transportation is replacing several luminaires in Island, King, Snohomish, Skagit, Thurston and Whatcom counties with new, energy-efficient light-emitting-diode (LED) luminaires. In addition, some lights will be removed as part of a new, more efficient approach to highway lighting.
What to expect
Travelers can expect minor delays during installation and replacement of the luminaries. A construction schedule will be posted in 2022.
