The New Hampshire Department of Transportation has approved a procedure making it easier to move oversized loads, including manufactured housing, through the state.

In August, the state began vigorously enforcing the road height limit of 13 feet, 6 inches that was adopted in 1986, the Concord Monitor reported. But officials said customers are demanding larger homes, and home manufacturers have been mislabeling their loads as 13 feet, 6 inches - even when they are taller on flatbed trucks.

Builders and buyers of manufactured homes in the state have since complained about resulting delivery delays. They've had to transport the roofs separately or take a longer route through Canada.

Under the new procedure, a unit up to 14 feet, 3 inches that otherwise meets size requirements can get a permit immediately to move through New Hampshire on I-89, I-93 and I-95, and state Route 101.

Permits reportedly can be issued for other state highways after a study to make sure there are no obstacles for vehicles that high. Previously, the state allowed waivers for larger loads, but required an engineering review of the entire route and a public hearing before issuing each special permit.
