Dayton Street Utility Improvements

Project Limits


Paving overlay on Dayton Street from 6th Ave to 9th Ave re-scheduled for July 16, 17, and 20, weather permitting.

Crews plan to complete the paving overlay of Dayton Street from 6th Ave to 9th Ave on Thursday, Friday, and Monday July 16, 17, 18 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 July 16, 17, and 20 to avoid delays getting in and out of driveways during construction. During this work you may experience traffic delays due to:

    ·   Intermittent road closures along Dayton Street while asphalt is placed, compacted,                 and cools.
    ·   Intermittent closures of the 6th Ave, 7th Ave, 8th Ave, and 9th Ave and Dayton                        Street intersections lasting up to 4 hours each.
    ·   Short-term driveway access restrictions lasting up to 4 hours.

Please keep in mind this work is weather-dependent and the schedule is subject to change and that additional closures are planned in the future.  We will continue to provide updates on the work schedule as adjustments are made and final timelines and impacts of the work are determined.

What to expect during construction
Construction in Phase 2 will occur along Dayton Street between 5th Ave and 9th Ave and will include single-lane closures on Dayton Street, intermittent intersection closures, and other traffic impacts. As a refresher, we will be replacing aging and undersized utilities along Dayton Street. Improvements will include:   

    ·   Adding stormwater pipe capacity to reduce flooding downtown during                                      heavy rainstorms
    ·   Sewer pipe repairs and replacing potable water pipes that are nearing the end                       of their lifespan
    ·   Road Restoration and replacing the 5th Ave and Dayton Street intersection and                       concrete crosswalks
    ·   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 Ave to 8th                            Ave, where there currently is no sidewalk.

Removal and replacement of maple trees near Edmonds Library
In Fall 2020, the Edmonds Parks Department will plant new trees to replace the ones that were removed.

Community Transit Routes 116, 130, and 416 have returned to regular routes

Community Transit Route 116has been rerouted between 3rd and 9th avenues for Phase 2 construction. Several stops along Dayton Street have been relocated for the duration of construction. We will continue to share information related to transit routes as the project progress. For up-to-date details about bus routes, please visit Community Transit’s rider alerts page.

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
