BRUNSWICK — Mid Coast Hospital plans to open a walk-in medical clinic and offices at Maine Street Station.

As the anchor tenant of the downtown development, Mid Coast Hospital will use nearly half of a new 20,000-square-foot, two-story building. The walk-in clinic for non-emergency care is the first in the area. Mid Coast Medical Group’s adult primary care relocate from its current location at 81 Medical Center Drive.

Construction of the $5 million building is expected to begin this fall. The building is expected to open in late spring.

Maine Street Station is a project of Massachusetts-based JHR Development.
