WESTPORT — The historic swing bridge, carrying Bridge Street/Route 136 over the Saugatuck River — closed to traffic Thursday afternoon when it became stuck while being repaired — reopened later in the day.

In an alert about 3:30 p.m. Thursday, police said the 139-year-old span — formally known as the William F. Cribari Memorial Bridge — was open again for traffic after it was rendered impassable about noontime.

Police said they will issue a public notice if more repairs by  the state Department of Transportation are planned to the bridge Friday.

The metal bridge was stuck in the open position Thursday as repairs were being made by DOT crews, according to an initial alert from police. While the span was closed to traffic, police officers were deployed to key traffic intersections in the Saugatuck area — notorious for traffic congestion during rush hours — to help ease traffic flow.
