  1. Weight:Single – 22,400 Tandem – 40,000 Tridem – 60,000. Connecticut does not go strictly by axle weights. They will go as high as 25,000 on a single, providing that the manufacturer’s rating is not exceeded and provided that the gross is within the limits stated above for 5, 6 or 7 axles. Over 14? wide, 14? high or 120 long is considered a Super Load. Over 140,000 lbs. requires an engineer review. Note: the maximum superload width in Massachusetts is 16 feet.

  2. I have the opportunity to purchase a shed with dimensions of 14Wx16Lx14H. Would it be feasible to ship through CT towns? i.e. Bethlehem and Bantam into northern New Milford — Rt 202?

    1. I guess it all depends on what your are paying for the shed. 14′ wide and 14′ tall isn’t overkill but then again that depends on the route obstructions (if any) and the trailer type you intend on loading it on.
