Late night and early morning drivers can expect delays through Renton on Tuesday night and Wednesday morning.
Washington State Department of Transportation crews will perform a rolling slowdown in each direction on I-405 from SR167 to SR 169 between midnight and 4 a.m. to install temporary lighting wires above the freeway.
Crews will also close up to two lanes in each direction on I-405 in the same area from 9 p.m. to 4:30 a.m. for construction work.
