The Memorial Bridge, which runs over the Piscataqua River between New Hampshire and Maine, a 1,200-ft-long, two-year-old bridge, is set to become a “living bridge”—a piece of self-diagnosing, self-reporting smart infrastructure studded with approximately 250 sensors. This array will monitor traffic, vibration, stress, temperature, wind, humidity and precipitation simultaneously, in addition to accumulating values related to water quality, turbidity and the effects of any ship impacts. These sensors will be powered by a tidal energy turbine on one of the bridge piers.
