The road under the railway bridge at Needham Market remains closed a week after a barrier was damaged in a crash.
Suffolk Highways said the Coddenham Road railway bridge, which was named the 'most bashed' in Britain last year, has been sealed off to drivers after the incident last Friday.
In November last year, Network Rail said the bridge had been struck a total of 19 times in the last 12 months –costing about £41,000 in rail delays and cancellations.
Works to repair the barrier have started, but Suffolk Highways has said they are due to be completed by Monday, July 4.
However, a Suffolk Highways spokesman said the road could reopen before then if the works are completed sooner.
