Massachusetts Turnpike Authority Permits

General information

Irreducible load permits are available if the vehicle exceeds the maximum width, height, or length.

Permits issued by the Massachusetts Turnpike Authority (MTA) are not transferable to another vehicle. Upon application for an irreducible load permit, the applicant must demonstrate the number of work hours required to dismantle the load.

MTA does not issue a special permit with respect to weight, and a vehicle may not use a way, if the vehicle exceeds the gross vehicle weight rating or the registered gross weight.

Special hauling permits are required if the vehicle or combination exceeds the federal bridge formula weights or either of following:

Type of Vehicle	Maximum Weight
Motor vehicle with 2 axles	46,000 lb
Vehicle or combination with 3 axles	73,000 lb
Vehicle or combination with 4 or more axles	87,000 lb
Vehicle or combination with 5 or more axles	99,000 lb

Axle Spacings	Maximum Weight
A single axle or axles spaced less than 6 ft apart	18,000 lb
Axles spaced 6 ft or more apart	22,400 lb

A vehicle weighing more than the maximum vehicle weight specified above does not require an irreducible load permit for the use of the Ted Williams Tunnel, including the South Boston Bypass Road, provided that the Commissioner of Highways has issued an annual permit for construction equipment for the vehicle, allowing the vehicle to operate at a higher weight. An original annual permit issued for construction equipment must be kept in an accessible place in the vehicle to which it was issued and must be presented to an officer or MTA personnel upon demand.

Special hauling permits are required if:

The width is greater than 8 feet 6 inches for use of the Tunnels and the vehicle width is greater than 13 feet or use of a way other than the Tunnels; or

The height is greater than the maximum vehicle height for the way upon which the vehicle is traveling, as follows:

Way	Maximum Vehicle Height
Turnpike	13 ft 6 in
Ted Williams Tunnel	13 ft 6 in
Callahan Tunnel	12 ft 6 in
Sumner Tunnel	12 ft 6 in
Thomas P. O'Neill, Jr., Tunnel	13 ft 6 in
Prudential Tunnel	13 ft 6 in
CANA (City Square) Tunnels	13 ft 6 in
Other way not listed above	13 ft 6 in

For use of the Tunnels, a permit is required if the vehicle length is greater than the maximum vehicle length in the table as follows, and in the case of a tandem unit operating on a way, in the note below:

²The vehicle length includes front and rear bumpers, but does not include a load overhang up to 3 ft beyond the foremost part of the front transporting vehicle or more than 4 ft beyond the rear bed of the rear vehicle.
³A number of vehicles may be transported in combination by means of saddlemount combination or fullmount mechanism.
⁴A tandem unit may operate on a way without a special permit with respect to its length, provided that the overall total number of semitrailers or trailers in the tandem unit is no greater than two; each semitrailer or trailer of the tandem unit does not exceed 28 ft in length, without regard to the overall length of the tandem unit; and a tandem unit with semitrailers or trailers that do not exceed 28 ¹/₂ ft in length, if such semitrailers or trailers were actually and lawfully operating on December 1, 1982, as part of tandem units within a 65 ft overall length limit in any state, may similarly operate on a way without a special permit with respect to its length.
