The bridge reopened around 9 p.m. on Wednesday after railroad workers repaired the wooden subsurface beams that support the asphalt road, said Aaron Donovan, an LIRR spokesman.
“We don’t foresee a need in the short-term future to do additional repairs at this point,” he said.
William Pyne, assistant supervisor of the LIRR’s buildings and bridges department, said the small repair would take a couple of hours and that a crew was on its way. He said the cracked plank had been flagged by an inspector.
The Cranberry Hole Road bridge in East Hampton was shut down as a precaution on Wednesday after the Town Highway Department noticed a broken wooden plank, according to Town Highway Superintendent Stephen Lynch and Police Chief Ed Ecker Jr.
Workers noticed the loose, cracked plank sometime around 9:30 a.m., notified the police, who shut the bridge down, and reported it to the Long Island Rail Road, whose tracks run beneath the bridge.
“We’re not sure of the extent of the damage,” Mr. Lynch said around 4:30 p.m., adding that his department had not yet heard back from the LIRR.
“The railroad will come out and fix it. It’s their bridge,” he said.
He could not offer an estimate of when the bridge might reopen.
The LIRR could not immediately provide information.
