GORHAM, Maine (WGAN)  The Maine Department of Transportation says the Gorham Bridge on Route 237 has been posted.

MaineDOT says the bridge that carries Mosher Road over the Little River in Gorham is being posted at a weight of 38 tons.  Vehicles heavier than that should use Route 25 (Main Street) and Route 4 (Gray Road).

The department says this is a permanent change that goes into effect immediately.

Transportation officials say the weight limit will allow cars, pickup trucks, school buses, heating oil trucks and most emergency vehicles to use the bridge.

Large trucks, loaded dump trucks and large fire trucks will be required to use the alternate route.
