Northeast 137th Avenue Corridor Completion
Project details
Improvements widened the existing vehicle travel lanes to keep one lane in each direction and added a center turn lane north of Northeast 59th Street to Fourth Plain Boulevard. The finished project includes sidewalks, bike/mobility paths, roundabouts, utility upgrades, street lighting, traffic signal modifications at Fourth Plain, and landscaping along the new corridor.
New street elements
- Restriped the existing Northeast 49th Street roundabout from a two-lane to a one-lane roundabout
- New roundabout at Northeast 52nd Street
- New roundabout at Northeast 54th Street
- New roundabout at the southern Northeast 59th Street to realign this offset intersection
Overall, this project improved safety, increased mobility, and enhanced connectivity along the corridor.
Project background
Planning for this project included determining whether to use traffic signals or roundabouts, resolving questions about rights-of-way and stormwater drainage, completing an environmental evaluation, designing a crossing of Burnt Bridge Creek, and selecting pedestrian and bicycle facilities. We coordinated with utility companies and local, state, and federal agencies.
We determined that improvements to this street were needed to enhance safety, manage access to the fronting properties, and minimize the delays caused by turning vehicles. Improving the segment from 49th Street to Fourth Plain Boulevard was the last piece needed to complete the corridor.
Public input
The City provided information through communications with area neighborhood associations, and the public has participated and given input through stakeholder interviews, sounding boards, and two open houses.
