This project was developed to address congestion on a section of SR-527 between 164th Street SE and 132nd Street SE. SR 527 highway passes through downtown Mill Creek.
The purpose of the project is to improve traffic congestion, operations, and safety; provide facilities for transit and pedestrians; and encourage economic redevelopment along the SR-99 corridor through the city of Des Moines.
The purpose of this project is to improve safety and reduce accident frequency and severity. Within this section of SR-20, a primary issue is upgrading it to bike touring standards.
The goal of the project was to integrate consideration of highway landscape corridor public perceptions into DOT planning and decision-making by developing a method to engage DOT staff in a variety of design, engineering, and maintenance disciplines... more
