Cromwell Drive Northwest - Slope Stabilization (CRP 5866)

What’s Happening

A project to stabilize a 175-foot-long section of slope along Cromwell Drive Northwest started July 13. The work is expected to be complete in mid-August.  

The section is located on the north side of the road just east of 56th Avenue Court Northwest. 

Work hours are 7 a.m. to 5 p.m. Tuesday to Friday the week of July 13. Hours will be 7 a.m. to 5 p.m. Monday to Thursday during the remainder of the project.

Traffic impacts

Cromwell Drive Northwest will be closed at 56th Avenue Court Northwest from July 13-Aug. 13. A detour route will take motorists from Cromwell Drive Northwest to 50th Avenue Northwest to 24th Street Northwest to 62nd Avenue Northwest to Cromwell Drive Northwest.

Those accessing properties on 56th Avenue Court Northwest should come from 62nd Avenue Northwest. Access for emergency vehicles will be maintained.

The sidewalk on the south side of the road will remain open.

About the Project

The slope has been sliding and failing over time. Black tarps are in place to protect the slope from erosion and damage from rain events.

Crews will remove the tarps and then clear loose rock and soil from the slope. 

The slope will be stabilized using shotcrete, an application method where a four-inch layer of concrete is sprayed onto the slope, matching its contours. Before the concrete is applied, crews will install metal bars across the slope to tie the concrete to the slope. 

Massana Construction is the project contractor. The construction cost is approximately $353,000 and is funded with County Road Funds.

Plans, specifications, and bid tabulations for this project are available through the Pierce County Procurement and Contract Services website. Access is provided by going to
