172nd & Foster Traffic Control

We will be installing a three-way stop at SE 172nd Avenue and Foster Road.

Project Information

  • Location: Intersection of 172nd & Foster (see map)
  • Schedule: Planned 2029
  • Estimated Cost: $850,000
  • Funding Source: County Road Funds

Project Description

We are improving the intersection of SE 172nd Avenue and Foster Road. We will install a three-way stop, with new turn lanes to keep traffic flowing.

The current pattern causes traffic to back up along 172nd. The new improvements will reduce delays from 172nd and improve safety for everyone.

We may conduct survey work at times while the project is being planned and designed. 

Traffic Impacts

Traffic impacts will be announced after project design is complete.

When survey crews are present, please drive carefully and observe all traffic controls.
