The construction cost for this project is approximately $8 million. Approximately 44 percent of the construction cost is from Federal Surface Transportation funding, distributed by the Puget Sound Regional Council. An additional 44 percent is funded by the Washington State Transportation Improvement Board. The remaining construction funding is provided by the city of Mill Creek and Snohomish County.
Such funding speaks to the significance the project will have on the improvement of vehicular and pedestrian safety and congestion in the area.
