15th Ave S Improvements
Updated: April 14, 2021
What’s happening now?
Road closure at S Angeline St and 15th Ave S the rest of the month
Crews will be completing drainage work and road repairs on S Angeline St at 15th Ave S. As soon as April 15, S Angeline St will be closed on the east side of 15th Ave S. It will reopen by the end of April. There will be no through-traffic allowed on S Angeline St between S Columbian Way and 15th Ave S. 15th Ave S will remain open. Pedestrians and cyclists should follow signs and directions from crew members to move safely around the construction activity at the intersection.

Project Overview
15th Ave S between S Spokane St and S Angeline St is a two-way arterial serving southeast Seattle. This stretch of road provides an important connection for people traveling between Beacon Hill and Rainier Valley. SDOT wants to ensure that these improvements contribute to a safer space for all travelers and balance the needs of all modes of transportation, so that everyone can get where they need to go safely and conveniently.
We're repaving about 1 mile of 15th Ave S between S Spokane St and S Angeline St and a section of S Spokane St between S Columbian Way and 18th Ave S.
In addition to paving, we're making improvements at the 15th Ave S and S Columbian Way intersection. These improvements include a new pedestrian-friendly peninsula and updated roadway striping. Contrary to earlier plans, we're not building a plaza and the left turn signal at S Oregon St and 15th Ave S will remain. For more details about the improvements at this intersection, please see the maps below.

Temporary bus stop closure and relocation
Due to construction nearby, the northbound bus stops at S Oregon St - on 15th Ave S and on S Columbian Way - have been consolidated and relocated. Riders can now board buses on the east side 15th Ave S, just south of S Nevada St. This arrangement will be in place until May 2021, when the intersection work is scheduled to be completed. Construction schedules are subject to change; for more information about bus routes and schedules, visit the King County Metro website.
The scope of this project includes:
- New pavement: This will extend the life of the pavement, making the roadway safer and smoother for travel
- Drainage improvements: Improving drainage in the area will extend the life of the roadway and make the streets safer and smoother to use
- Slip lane: This project will improve the slip lane (the right-turn-only lane) at 15th Ave S and S Spokane St
- Upgraded pedestrian push buttons: We'll update push buttons in select locations to meet Americans with Disabilities Act (ADA) standards
- Upgraded curb ramps: In select locations, we'll update curb ramps to meet ADA standards
- Improved and updated sidewalks: We'll repave select sidewalks in need of repair
- Improvements at 15th Ave S and S Columbian Way intersection: We'll install a pedestrian-friendly peninsula, new curb bulbs, and improved connections for bicycles.

Project Background
Each year, we pave arterial streets in poor condition to make them safer and smoother, and to extend their useful life. We prioritize paving projects based on pavement condition, traffic volume, geographic equity, cost, and opportunities for grants or coordination with other projects in the area. Paving streets also creates opportunities to improve street safety and move people and goods more efficiently in a growing Seattle. Read more about our current paving projects here.
