The Lagoon Pond drawbridge was back in working order Monday evening after it was closed for more than three hours, rerouting traffic and prompting an advisory to motorists from Tisbury police and the Steamship Authority.

Tisbury police tweeted at around 6 p.m. that the drawbridge was stuck, advising motorists to seek alternate routes.

At 6:30 p.m. the Steamship Authority posted a travel advisory reiterating the problem.

Reached later, Tisbury police Sgt. Chris Habekost said the problem occurred when one of the arms on the bridge that blocks traffic broke.

The problem was repaired by 9:15 p.m. and the bridge was again was again open to all traffic, the sergeant said.

He said Massachusetts state police and Mass DOT assisted with putting up roadblocks.
