The north span of the new Memorial Bridge connecting New Hampshire and Maine is in place. Work is now expected to start on the center lift span of the bridge connecting Portsmouth, N.H., to Kittery, Maine. The north span on the Kittery side was successfully moved into place early Wednesday. The south span was put into place in January. Denis Switzer of the New Hampshire Department of Transportation says the goal is to complete the project by July 6. He tells the Portsmouth Herald (http://bit.ly/WWllwe) the center span is the most difficult part of the job because it is a moving part. Operating the span includes hooking up counterweight cables and installing electrical wiring.
