Minnesota Deploys Drones to Care for Aging Bridges

Bridges don't last forever without at least some occasional repair, but how do city officials know when an aging bridge is in need of reconstruction? Typically, an individual has to bungee down to inspect it or specialized (and extremely expensive) equipment must be employed. That's why Minnesota is testing out the use of drones to do the work. Although not able to be used in every instance, these specialized drones that can be flown sans GPS, are able to get to places originally untapped during bridge inspections and so far have proven to be a highly useful tool.
