A fall exhibit at the Custom House, "A Merrimack Motif: A Bridge to Our Past," focuses on the history of the Chain Bridge. A collaboration with the Amesbury Cultural Council, it runs through Oct. 30.
"We've got a grand program," Mroz said.
The Custom House was designed by Robert Mills, architect of the Washington Monument and U.S. Treasury Building, and was built in 1835. The museum is managed by the Maritime Society.
