An image of the construction projects around Mill CreekMill Creek community members and drivers who travel through the city will need to plan ahead for local travel in late spring and summer 2018 due to numerous roadway projects. Project timelines are weather-dependent and schedules may shift as needed.

“Sometimes construction projects are planned years in advance, and schedules, contractor availability, weather, and timing of funding may result in overlap with other projects,” said Gina Hortillosa, director of Public Works and Development Services. “This year, the City is working with six other agencies that have local projects to understand impacts and coordinate the work as best as possible.”

An open house with information on the following projects will take place on Thursday, April 12, from 5:30 to 7:30 p.m. at Mill Creek City Hall North, Large Community Room, 15720 Main St.

The City of Mill Creek will break ground on its most significant capital project to date – the reconstruction of 35th Avenue SE where flooding over the roadway has caused lane closures in recent years. Work is slated to begin in April and will result in full closure of 35th Avenue SE between 141st and 144th Streets SE in Mill Creek through October. The planned detour route is via 132nd Street SE and Seattle Hill Road. Additional information will be forthcoming on this project in the next several weeks. The public is encouraged to sign up for project notifications at

Snohomish County is undertaking two projects in Mill Creek. It will complete the Seattle Hill Road project between 35th Avenue SE and 132nd Street SE, with one planned full-weekend closure of the roadway in April. The closure will happen while 35th Avenue SE is still open, and will not impact detour traffic. The work is slated to wrap up in August. Project information is online: The County also will start construction on 35th Avenue SE between 152nd Street SE and 180th Street SE in April; this project will continue through summer/fall 2019. While there will be single-lane closures for the duration of the project, four weekend road closures are anticipated in concentrated areas. Project information is online:

Washington State Department of Transportation will undertake a night-time grind and overlay project on SR 96 between I-5 and Hwy 9 via Seattle Hill Road and Lowell Larimar Road. In Mill Creek, 132nd Street SE will be impacted by lane closures. The project is scheduled to begin in April and wrap up in September.

Community Transit work on the Swift Green Line is underway and will continue through 2019. This includes installation of bus stops and extending turn lanes in Mill Creek along 132nd Street SE and SR 527. Work occurs during daytime and nighttime hours. Single lane closures are expected in concentrated areas, and periodic two-lane closures will occur when concrete pads are installed in the roadway. Project information is online:

Puget Sound Energy gas line work is occurring on 164th Street SE. Current work in unincorporated Snohomish County is taking place during the day. However, when the work moves into Mill Creek in April, work will occur at night and will impact one or two lanes at a time. The project will extend down Mill Creek Blvd and onto Main Street in front of City Hall South. The work is slated to wrap up in July.

Snohomish County Public Utility District will have localized cable replacement work in Mill Creek in the fourth quarter of the year. However, impacts will be limited.

A project outside of Mill Creek will impact the Mill Creek community. WSDOT will undertake a significant grind and overlay project on westbound Hwy 2 that includes nine weekend closures in summer 2018. The anticipated detour route is via Hwy 9 and 132nd Street SE.

Finally, construction on Mill Creek’s Exploration Park in the North Pointe Neighborhood will begin in May and conclude in August. Impacts are limited to the North Pointe neighborhood, and will include single-lane closures. Additional project information will be forthcoming, and details are online:

“There is a lot of work taking place,” said Hortillosa. “We encourage people to understand how they will be personally impacted and plan ahead.”
