The drawbridge connecting Kittery with Portsmouth, N.H., was closed to vehicles today after a detailed inspection found significant deterioration.

Memorial Bridge was closed at noon to all but pedestrian and bicycle traffic, according to a press release from the New Hampshire Department of Transportation.

An inspection found two gusset plates, which connect bridge beams to load-bearing columns, were unsafe. Both are on the southbound side of the bridge.

Traffic was directed to use either the Sarah Long Bridge, which is the U.S. Route 1 Bypass or the Interstate 95 bridge.

Transportation officials from the two states are discussing what repairs are warranted since the bridge is scheduled to be demolished in favor of a new bridge a year and a half from now.
