Weight limits reduced for bridges on Hawaii, Maui, Oahu, and Kauai

Posted on Feb 13, 2018 in Highways News, Main, News

Signs notifying motorists of revised weights to be installed by February 15.  

HONOLULU – The Hawaii Department of Transportation (HDOT) will be installing signage advising motorists of weight limit reductions on bridges on the islands of Hawaii, Maui, Oahu, and Kauai. The weight reductions are in effect from the date of the posting until such time that they are lifted. HDOT will post all weight reduction signs at the bridges mentioned in this release by Feb. 15, 2018.

The bridge weight limits vary, but do not have any effect on passenger vehicles, which typically weigh two tons. Emergency vehicles, buses, and tractor trailers may be affected. HDOT is coordinating with county emergency response and public transit agencies on access to these areas for their vehicles.

Commercial vehicles and trucks with routes taking them over these bridges should apply for an overload permit, adjust their loads, or consider alternate routes. More information on overload permits for state roads and bridges can be found at this link. More information on overload permits for the County of Maui bridges can be found at: https://www.mauicounty.gov/1303/Moving-Permit

HDOT is putting these weight limits in place due to a recent reassessment of how the state calculates bridge weight restriction to take into account heavy truck loads. Some of the weight restrictions for bridges on the list may be removed or reduced following further testing, analysis and/or with ongoing or future bridge repair projects.
