Hand Rd Culvert Replacement

Update August 2019

Snohomish County Public Works is delaying the construction window and closure of the site at 12325 Hand Rd by two days. The new closure window is scheduled begin at 5 a.m. on Wednesday, Aug. 14, 2019 and reopen at 10 p.m. on Tuesday, Aug. 27, 2019.


Snohomish County Public Works will be replacing twin culverts under the road near 12325 Hand Rd east of Monroe during August 2019. The current 24-inch diameter twin culverts are undersized which creates a partial barrier for fish. The twin culverts will be replaced with a single 14-foot wide concrete box culvert to allow for improved fish passage.


Work will take place August 14-27, 2019.

Traffic Impact

To install the new culvert the road will be closed near 12325 Hand Rd from August 14-27, 2019. The detour route will be signed and utilize Old Pipeline Rd, Woods Lake Rd and Florence Acres Rd. Local access will be provided to residents living between Old Pipeline Rd and Florence Acres Rd during the closure.


The estimated cost for this culvert replacement is $250,000 and will be paid for through Surface Water Utility funds.
