Traffic along Beach Road was detoured for hours Friday after the Lagoon Pond drawbridge was stuck in the open position. 

The Massachusetts Department of Transportation announced around 5 p.m. that the bridge that connects Oak Bluffs and Tisbury was temporarily closed and officials were investigating the cause. Officials later said there was a problem with a fuse. 

Tisbury police warned drivers about the malfunctioning crossing earlier in the afternoon and it was still stuck several hours later. Signs on roads leading into the towns urged people to seek alternative routes.

Police details were in the area to help direct traffic and drivers were told to expect delays.

Oak Bluffs police reported around 9:30 p.m. that the bridge had reopened. 

The new drawbridge, which replaced its 1935 predecessor, opened to vehicular traffic in 2015 and the first boat crossed underneath the following year. The 350-foot-long bascule bridge opens and closes by a pivoting weight and cost $43.7 million to build.
