State officials said they are implementing new weight limit restrictions for bridges on the islands of Hawaii, Maui, Oahu, and Kauai due to a recent calculation reassessment taking heavy truck loads into account.

Most passenger vehicles, which typically weigh two tons, should not be affected, according to state Department of Transportation officials. But emergency vehicles, buses, and tractor trailers may be affected. State officials said they are coordinating with county emergency response and public transit agencies on vehicle access to these areas.

Commercial vehicles and trucks with routes taking them over these bridges should apply for an overload permit, adjust their loads, or consider alternate routes, officials said.

Signs advising motorists of the new weight limit reductions at bridges are being posted this week, officials said. Here is the island-by-island list:

Oahu

>> Nuuanu Stream Bridge, westbound on Nimitz Highway between River Street and Awa Street, new weight limit 28 tons.

>> North (Lower) Poamoho Stream Bridge, on Kaukonahuna Road (Route 930) about 400 ft. northeast of Hukilau Loop, new weight limit 12 tons.
