Interurban Avenue South Project

Project Update: June 2016

The Interurban Avenue South Project was completed on June 16, 2016.


Project Overview

The City of Tukwila has selected a Contractor and Construction Management firm to begin reconstruction of a portion of Interurban Avenue South from Fort Dent Way to S. 143rd Street. The $7.5 million project will include a new retaining wall to support the roadway adjacent to the Green River, extensive storm drainage improvements, new pavement, lighting, pedestrian facilities, landscaping and other improvements. Utility companies are relocating their facilities just ahead of construction to accommodate the roadway improvements.

The roadway construction work began in July and will last 12 to 16 months. Throughout significant portions of the work there will only be one lane of traffic in each direction within the construction zone. Access to local businesses will remain open during construction but some limited interruptions can be expected and access may be restricted at specific locations to accommodate the modified traffic patterns. Equipment noise, dust and other unpleasant consequences that are a normal part of the roadway construction process will be noticed but the contractor will do their best to limit these inconveniences. Through traffic moving between the I-405 and I-5 interchanges are encouraged to find other routes throughout construction. Speed limit in the construction zone is 25 MPH and will be strictly enforced. Please drive carefully and keep construction workers safe.
