ATHOL — A local convenience and gas plaza’s expansion plans could straighten out a Main Street intersection.

Mr. Mike’s Market sits at the intersection of Main Street and Lake Ellis Road, with a Dunkin’ Donuts and a Mobil gas station. The owners plan an expansion and renovation.

To that end, Town Administrator Shaun Suhoski said the company is looking to swap and assemble a number of parcels, creating a contiguous development site for them and a perpendicular intersection for the town.

Lake Ellis Road currently meets Main Street at a roughly 45-degree angle. Suhoski said the proposed 90-degree intersection is supported by the police, fire and public works departments. The mouth of Lake Ellis Road would shift uphill to sit between the fire station and the former Lyman Ward School.

Representatives presented the idea and preliminary designs to the Board of Selectmen this week. The proposal goes next to the Planning Board and Finance Committee. Attorney Brian Beaton said the plan is conceptual at this stage, pending input from the boards and a town meeting vote. Suhoski said there will be five articles on the town meeting warrant related to the plan.

Annual and special town meetings are scheduled for June 13.
