PORTSMOUTH/BRISTOL — The new 30-ton weight restriction for the Mt. Hope Bridge applies only to certain vehicles, the Rhode Island Turnpike and Bridge Authority (RITBA) stated in a “correction” to an earlier press release that was released today. Jan. 6.

As of Dec. 29, 2022, the maximum vehicle weight allowed on the Mt. Hope Bridge was changed from 40 tons to 30 tons, but now RITBA is saying the rule applies only to certain vehicles with six or more axles.

“After additional research, we learned that the change in the tonnage allowance would apply only to specific trucks with six or more axles,” said Lori Caron Silveira, RITBA’s executive director. “There are few of these trucks on Rhode Island roads so the change will apply to very few users. We apologize for any confusion.”

The modified weight allowance is due primarily to a Federal Highway Administration load rating manual update. It’s also required because of an “as-built” design factor which has existed since the bridge opened in 1929, according to RITBA. The as-built factor involves the outside girders, some of which were reinforced with steel plates approximately 50 years ago.

The reduction in maximum vehicle weight is not related to bridge maintenance or the upcoming dehumidification project, RITBA says.

RITBA is coordinating with the R.I. Department of Transportation’s bridge and traffic engineers to identify and communicate detour routes for impacted drivers. RITBA is also doing outreach to the municipalities and commercial enterprises affected by the new restrictions to ensure that emergency vehicles and freight carriers are aware of the new weight limit posting.
