Windham’s Board of Selectmen is planning a special election in September to obtain funding for a secondary access road for the new high school currently under construction.

The new road would overlap the current London Bridge Road, connecting the entrance to the high school on Route 111 to Castle Hill Road behind the high school, said Town Administrator David Sullivan.

The proposed warrant for the special election asks for voters to authorize taking out a $1.25 million bond and to accept any forthcoming grants toward the project costs. The Board of Selectmen approved the warrant at their meeting on Monday, June 9.

Sullivan said the town had planned on putting the project on its budget, but Selectman Charles McMahon submitted a petitioned warrant article for the townwide vote last March to put it on the school district budget, which would allow the project to qualify for 30 percent state reimbursement.

That warrant article failed with voters. The project does not qualify for state reimbursement, Sullivan said, because it will not be a part of the school district’s budget.

“The way we’re moving forward, it’s going to be part of the town’s budget,” Sullivan said.

A hearing on the conditional layout of the road, which would include construction parameters, width and a Board of Selectmen decision on whether the road is necessary will take place Monday, July 21, Sullivan said.

Prior to taking public input, the board will attend a site walk of the future road starting at 6 p.m. Sullivan said a deliberative session for the warrant will take place the week of Aug. 6, with the hope of including the warrant on the primary ballot for Tuesday, Sept. 9.
