Maine Dept. of Transportation (DOT), through the City of Westbrook and the Town of Windham, has received funding to complete the design and engineering for the 5-mile Windham to Westbrook section of the Sebago to the Sea Trail (also part of the Mountain Division Trail). Once this phase is complete the project will be "shovel ready" and the next phase of funding will need to be secured through the leadership of the municipalities and DOT.

The 4.8 miles section from South Windham to Westbrook is open for pedestrian use while the railbed remains inactive. The first 1.5 miles from South Windham is a flat, easy-walking path on an undeveloped railbed. The remaining 3.5 miles to Bridge Street in Westbrook is on railroad tracks. Please be aware of its rugged conditions.

Since 2007, members of the Sebago to the Sea Trail Coalition have been working to create one contiguous trail from Sebago Lake to Casco Bay.
