Dayton Street Utility Improvements

Project Limits


5th Ave and Dayton Street intersection closed Thursday, October 10.

Crews plan to close the 5th Ave and Dayton Street intersection on Thursday, October 10 to remove an existing underground structure.

During these closures:

Through traffic will be restricted
    ·    There will be some short-term driveway access impacts. We will be contacting                          businesses in-person if their driveway access is expected to be impacted and                          answer any questions or concerns you may have. 
The sidewalks at 5th ave and Dayton St intersection will be closed; pedestrian                         detours will be in place

Paving overlay on Dayton Street scheduled for Friday, October 11, weather permitting.

Crews plan to complete the paving overlay of Dayton Street from 3rd Ave to 5th Ave this Friday, October 11, weather permitting. Unlike previous paving work, crews will work on both sides of Dayton Street to complete this work. Please plan to park off of Dayton Street on October 11 to avoid delays getting in and out of driveways and parking garages between 3rd and 5th Ave during construction. During this work you may experience traffic delays throughout the day due to:

    ·        Intermittent road closures along Dayton Street.
    ·        Intermittent closures of the 3rd Ave and Dayton Street intersection and the                           4th Ave and Dayton Street intersection lasting 1-2 hours.
    ·        Short-term driveway access impacts lasting 1-2 hours.

Please keep in mind that this work is weather dependent. Crews cannot place the pavement during rain events as the pavement will not cure properly. If there is rain in the forecast, work will be delayed. We will continue to provide updates on when to expect paving to occur.

Looking ahead: Phase 2

To decrease construction impacts for phase 2 in 2020 and improve work flow during that period, some low impact work, mainly trenchless with associated spot excavations, for the sanitary sewer is expected to take place on Dayton between 7th and 9th in November and December 2019.  This work will require some construction traffic control resulting in minor delays, but traffic will remain 2 way and no intersection closures are expected.

Community Transit buses will be running on alternate routes around work zones. Please visit Community Transit’s website for current rider alerts and routes:

Phase 1 (May-October 2019) and Phase 2 (2020)

Phase 1 of construction (Dayton Street from 3rd Ave S to 5th Ave S) will begin on May 13, 2019 and is anticipated to be completed in Fall 2019. Work during this phase will occur mostly between 3rd Ave S and 5th Ave S. Some sewer pipe rehabilitation work between 6th and 9th may be part of phase 1.

Traffic and pedestrian impacts

arrow b   Sidewalks and driveways will remain open except for short durations to maintain safety throughout the corridor

Phase 2 of construction  (Dayton Street from 5th Ave S to 9th Ave S) will begin as early as Spring 2020 and last into Fall 2020

Project Description:

The Dayton Street Utility Improvements Project will replace aging and undersized utilities along Dayton Street from 3rd Ave S to 9th Ave S. Improvements will include:
    • Adding stormwater pipe capacity to reduce flooding in downtown during heavy rainstorms

    • Replacing sewer and potable water pipes that are nearing the end of their lifespan

    • Upgrading curb ramps to be ADA-accessible at the intersections of Dayton Street and 6th, 7th, 8th, and 9th Avenues

    • Adding a sidewalk along the south side of Dayton Street from 7th to 8th Avenues

Estimated Schedule:

  • Design was completed at the end of 2018

  • Phase 1 (3rd Ave S to 5th Ave S) construction will begin in May 2019

  • Crews do not plan to work between October 2019 and March 2020 over the holiday season

  • Construction will be divided into two phases. The second phase of construction (5th Ave S to 9th Ave S) is expected to start as early as Spring 2020 and last into Fall 2020


Replace and upsize existing utilities on Dayton Street from 3rd to 9th Avenue. Improvements will include:

  • Replacing 3200 feet of stormwater pipe

  • Replacing 3800 feet of potable water pipe

  • Replacing 4300 feet of sanitary sewer pipe

  • New pavement on Dayton Street throughout the project limits

  • Constructing a new sidewalk on the south side of Dayton between 7th 
    and 8th Avenues

  • Constructing ADA-accessible pedestrian curb ramps

  • Revise sidewalks and intersections at Dayton St and 6th, 7th, and 8th, and 9th Avenues


 ·  Construction costs estimated to be $7 million.
