PORTSMOUTH, NH (CBS) – A nearly century-old bridge that connects New Hampshire to Maine has been shut down.

Officials have decided the 88-year-old Memorial Bridge on Route 1 from Portsmouth to Kittery is too dangerous to remain open.

The two states are working on a replacement.

Construction of a new span is still about a year away.

In the meantime, drivers can still get back and forth using the Route 1 bypass and the I-95 bridge.
