Special consideration must be given to route planning to avoid Groton College Campus and the vicinity of Groton Commercial Zone, which have infrastructure limitations or heavy pedestrian traffic that may impede oversized loads.

Certain neighborhoods, such as Groton Center and areas around Groton Civic Center, have restricted access for oversize loads. Alternative routes should be planned in advance to avoid these areas.
