Beacon Hill Healthy Street

Updated January 24, 2024

What's Happening Now?

Safety improvements are coming to 18th Ave S and S College St!

As previously announced, we are beginning construction on safety enhancements planned for 18th Ave S and S College St as part of the Beacon Hill Healthy Street. Construction was originally scheduled to begin in 2023 but was postponed due to crew availability and other scheduled work.

To explore the designs for 18th and College, as well as the improvements planned for Beacon Ave S and S Hanford St, see the “Design Elements” section below. This winter, we will resume our evaluation and outreach for the South Beacon Hill Healthy Street.

What to Expect During Construction

We anticipate SDOT and SPU crews to begin construction as soon as January 26, 2024. To minimize impacts as much as possible, and due to challenging traffic controls at this tight intersection, work will take place over three (3) weekends of long work days. Delays are possible due to weather. 

  • Work will cause noise and vibration. SDOT has received a noise variance for this weekend work between 7:00 and 9:00 am in a residential neighborhood
  • There will be construction staging and parking impacts near the work site. We will place “No Parking” signs in advance of the closure.
  • At various times during construction, crews will have to close 18th Ave S access at the intersection, with detours in place for people driving. Traffic on College Street may be reduced and delayed.
  • Crosswalks and sidewalks will be closed, with detours in place for people walking and rolling.

Upgraded Temporary Sign Bases

We will also be upgrading the temporary sign bases at key intersections along this South segment to more durable concrete cylinders. The existing temporary signage has not been durable enough to withstand winter traffic conditions. As a result, our crews were overwhelmed last year with numerous daily requests to repair and replace signage all over the city. These temporary sign bases will be replaced with permanent planter boxes and concrete sign bases if this segment is made permanent.
