Phase 1 of the Main Street Revitalization Project reconstructs the deteriorating pavement along 236th Street SW from I‑5 to 56th Avenue W. Once completed, the roadway will provide one travel lane in each direction, a two-way center turn lane, and bike lanes. The improvements also include wider sidewalks with trees, decorative LED pedestrian and street lighting consistent with Town Center standards, and relocating existing overhead utilities underground. The project also upgrades the 236th/56th Avenue traffic signal, installs a new signal at Gateway Boulevard and underground facilities for the future traffic signal at the intersection of 236th Street and 58th Avenue.
ICI expects to begin onsite activities as early as Monday, March 4. Initial activity is anticipated to occur along the north side of 236th Street SW between I‑5 and 58th Avenue. Additionally, ICI will stage construction materials at the Civic Campus site, 23204 58th Avenue W., until City Hall construction begins later this year. ICI will also upgrade sewer facilities in the next few weeks along 56th Avenue at and near 236th Street to accommodate future Town Center development. This sewer work will minimize potential later impacts to the new 236th Street pavement. Construction work will expand later along the remainder of the 236th Street corridor.
Construction of Phase 1 is expected to continue throughout 2019 and into early 2020. Both directions of 236th Street will typically remain open throughout construction but full closures of the roadway (with local access coordinated with each property) will occur at various times. Bus stops along 236th Street SW will be affected during construction and Community Transit and King County Metro Transit will provide any necessary service alerts.
