D231: Horsehaven Creek Culvert at 188th Street East Project

Project Description

This project will raise 188th Street East to accommodate the new box culvert (bridge) that has a 19.5-foot span and 8-foot in height.

Construction is anticipated to take place between June 15 and Oct. 15, 2022.

The goal of this project is to improve fish passage and address flooding issues on Horsehaven Creek where it crosses under 188th Street East near Orting.

The existing culvert does not meet current fish passage requirements, and the area has experienced water over the roadway several times each year. 

The planned improvements include removing the existing 36-inch culvert, replacing it with a larger concrete structure and repaving the roadway.

Traffic Impacts

During construction, 188th Street East will be closed for up to 45 days, and a detour will be in place. More details on the closure will be provided at a later date.
