Current Outlook

This project is nearing completion, earlier than originally scheduled.  As of now, all traffic lanes related to this project are open in both directions.  There is some minor work left to complete including minimal landscaping and concrete/ fencing work.

Project Description

The NE 171st Street Urban Parkway Project is a road diet project consisting of the construction of a new roundabout at the intersection of 133rd Avenue NE and NE 171st Street. Work also includes two culvert replacements, hot mix asphalt overlay, planning, signal improvements, illumination, drainage improvements, water main relocation, cement concrete curb and gutter, cement concrete sidewalks, curb ramp replacement, traffic control, pavement markings, signing, landscaping, and irrigation. 

Project Duration

April 23, 2018 - Spring 2019

Project Impacts

Working hours

  • 7AM to 7PM (Monday - Friday) and 9AM to 5PM (Saturdays)


  • Until Project Completion:

    DURING CONSTRUCTION HOURS: lanes on NE 171st Street will be reduced to one-lane in each direction along with lane shifts. Most of the time there will be only one lane open for traffic heading in both directions.  Flaggers will alternate traffic direction for the one lane to accommodate travelers in each direction.

    NON-CONSTRUCTION HOURS: Eastbound and Westbound lane(s) will be open to thru traffic.
