But at the town forum in May, Carpenter had expressed concern about adding traffic lights to Route 111 where there are more than a half-dozen between London Bridge Road and Route 28.
“If we put all these in, you’ll have 12 traffic lights, about one every 1,000 feet,” Carpenter told selectmen.
Selectman Al Letizio Jr. has floated the idea of building a roundabout at the intersection.
But Carpenter has said he thinks there is too much traffic on Route 111 for roundabouts to work.
A state count from 2009 put daily traffic at 25,000 on Route 111 west of Route 111A.
LoChiatto pressed Carpenter at the May forum for what he would do about the lights.
“That’s your decision. Good luck with that,” Carpenter said to laughter. “The only idea I could come up with that appeases everybody, if we want to go that route, is to eliminate the new 111A lights, but build the road, and make it right in and right out southbound only.”
The town could then deal with the issue in five or 10 years, depending on how much development takes place in the area, he said.
