InternationalBridgeA few weeks after they were turned off, the lights on the International Bridge arches are back on Wednesday night. The lights were beign replaced to result in energy and maintenance savings for the bridge authority in the long term. The new LED bulbs will be turned on at 9:00 p.m. The new bulbs will coincide with the displays on the U-S and Canadian arches that represent each nation’s flag and follow a pattern similar to the strands that were installed during the bridge’s 50th anniversary in 2012.
