You may think of TDOT as a department that only builds roads, but did you know we also have an aeronautics division that is responsible for licensing and inspecting 74 airports across Tennessee?
At 40 of those sites are Automated Weather Observation System or AWOS. The systems are very helpful for pilots, the National Weather Service and even TV meteorologists! TDOT is currently in the process of upgrading all 40 AWOS systems across the state. All 40 AWOS systems should be updated by 2020 and will cost about $2.5 million.
