228th Street SE & 29th Drive SE Improvements

News & project updates

March 21, 2017

Kamins Construction will begin constructing this project at the end of March.


The project will include the design and construction of a new traffic signal and related intersection improvements with channelization, intersection lighting, ADA improvements, and other related work at the intersection. This project will help the flow of traffic on SR 527 and at the project intersection. The result will decrease the amount of idling time of vehicles and emissions along the SR 527 corridor due to the redistribution of traffic using this intersection rather than the congested intersection at SR 527 and 220th Street SE. With the improved efficiency of the intersection, it is also anticipated that it will be seen as more reliable and improved access to Canyon Park.


This project is included in the City’s Capital Facilities Plan (Project #T68) and funded through the 2015-2016 City Budget. Project funding was provided by a Surface Transportation Program (STP) grant from the Puget Sound Regional Council and from the City’s Capital Improvement Fund. The project has been added to the State’s Transportation Improvement Project (PDF) list as project number BOTH-44.
