Montville — Start your engines.

A Montville sporting complex plans to build a 100,000-square-foot indoor go-kart racing facility that the company says will be the biggest of its kind in the country.

The $7 million facility will contain two tracks totaling 0.25 miles, folded into a new building across from Wide World of Indoor Sports on Sachatello Industrial Drive, Wide World of Sports COO Robert Bonnell said Tuesday.

The Wide World of Indoor Sports opened its four-field indoor sports complex in the industrial complex off Route 85 in Oakdale in September 2015.

The company also owns two locations in North Smithfield and North Kingstown, R.I.

It plans to break ground on the new go-kart complex next month and open in October, Bonnell and Wide World General Manager Brett Donoghue said  Tuesday morning at the annual State of Montville event hosted by the Chamber of Commerce of Eastern Connecticut.

Customers will drive electric go-karts to avoid the emissions that traditional gas-powered go-karts create, he said.

The Montville Planning and Zoning Commission will consider the plan at its April 26 meeting.

The facility will draw racing enthusiasts from all over the state and region, Bonnell said, adding that the nearest indoor go-kart track is in Wallingford.

He said he hopes the facility will bring people to Wide World of Sports year round, even during the summer down time when business is quiet at the sports complex.

The track also will fill a gap in local recreational opportunities, Bonnell said.

The facility will include an indoor trampoline and dodge ball park.

"This should be a whole year-round activity," he said.
