PORTSMOUTH, N.H. (AP) - The final span of the new Memorial Bridge connecting New Hampshire and Maine is scheduled to be floated into place.
The U.S. Coast Guard has closed the Piscataqua River to maritime traffic early Monday to allow contractor Archer Western full access to the bridge and start the float-in.
Archer Western had assembled the span aboard the barge Cape Cod, which is docked at the Port of New Hampshire.
It's the most complicated of three spans to put into place.
River traffic won't be allowed for five days as the bridge is hooked up to various mechanical, electrical and computer connections. The bridge also would need to be tested.
River traffic would resume on June 22.
The bridge is replacing a nearly 90-year-old bridge connecting Portsmouth to Kittery, Maine.
