Ongoing Streetscape work in downtown Knoxville uncovered a cracked water main Thursday. Water service was cut off to the courthouse for a time, as crews repaired the main. City Manager Harold Stewart tells KNIA KRLS News that this underscores the importance of the Streetscape Project. He adds that the infrastructure under the streets around the square is very old, and is in urgent need of being replaced. Construction activities did not cause the break, according to Stewart.
