State highway officials were advising motorists last weekend to keep an eye out for workers relocating power lines on Interstate 405 as part of a larger project involving the Maple Valley Highway junction.

During daytime hours June 28-29, Puget Sound Energy had a truck on the southbound shoulder of I-405 between State Route 167 and State Route 169/Maple Valley Highway. The truck’s arm was extended over the median of I-405 to create a protective barrier while crews completed relocation of power lines, according to the state Department of Transportation.

No lanes were closed, but the work was a possible distraction for drivers, said DOT officials.

The lines are being moved in preparation for the second stage of the I-405/Interstate 5 to SR-169 widening and State Route 515 interchange project. Construction work is scheduled to begin late this year or early next year.
