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.
