English Grade Road and 316th St NW


English Grade Road will be closed to all through traffic at a point approximately 300 feet south of 316th Street NW to replace an undersized culvert. A Snohomish County crew will excavate this section of road to install a 35-foot long, eight foot wide, by three and a half foot tall replacement culvert to meet fish passage standards set by the Washington State Department of Fish and Wildlife.


Construction dates have not been identified. The work will take place sometime after July 15 and before September 30, 2014 for approximately six weeks.

Traffic impacts

A full road closure will be in effect for two weeks at a point 300 feet south of 36th Street NW.

The detour will be north from 316th St NW – English Grade Road – 324th Street NW – Brandstrom Road – 300th Street NW – English Grade Road. We regret the inconvenience and appreciate your patience during construction.

Temporary single lane closures may also be needed during this time.
