A broken-down semitruck and trailer is causing delays on Lake Washington Boulevard.

The truck, which has a large crane on the top, is stalled at the hairpin turn on Lake Washington Boulevard between Denny’s and the Newcastle Shell Station.

The road was partially blocked with traffic control as of 4 p.m. Thursday, according to an e-news blast from the city.

It will be fully blocked later tonight though, between 7 p.m. and 9 p.m. as workers clear the roadway.

The city says to avoid the area, if possible.
