PORTSMOUTH, N.H. — New Hampshire’s largest utility is contributing $40,000 to help light up the new Memorial Bridge.

Public Service Co. of New Hampshire announced the contribution Tuesday.

More than $100,000 had been raised toward the $200,000 goal of installing energy-efficient lighting on towers and along the deck of the new bridge, which will connect Portsmouth and Kittery, Maine.

The bridge is under construction. It is replacing a nearly 90-year-old span and is expected to open to traffic this summer.
