The exterior construction of the new Super Wal-Mart going up in Thomaston is about 90 percent complete, according to Code Enforcement Officer Bill Wasson.

"You could fit four football fields with their bleachers inside the massive structure," said Wasson, adding he uses that analogy to give people a better idea of the scope of its size.

The estimated cost of the construction is $28 million, according to Town Assessor David Martucci.

There are currently three lots on the 32-acre parcel of land with Super Wal-Mart taking up a majority of the space. Tractor Supply Co. will inhabit a 6.23-acre lot between Wal-Mart and Midcoast Federal Credit Union. A third lot with 2-acres of available space has yet to be sold.

The entrance to the new developments will be off Route 1, between Dorman's Dairy Dream and Midcoast Federal Credit Union.

"It is a real plus for Thomaston. We are ideally suited for this," said Wasson.

The new facility is slated to open in October of this year. Thomaston Planning Board approved the project in September 2011.
