Preparation for Music City Loop continues with controlled blasting to excavate the TBM launch shaft - the final depth will allow tunneling safely beneath existing utilities.
We greatly appreciate the partnership and oversight from @TennDGS, @myTDOT, @NashvilleDOT, and the State Architect for their thorough review and approval process.
Each blast is carefully engineered and monitored to limit vibration, protect nearby structures, and ensure public safety. Vibration in the nearest building was monitored and recorded to be less than that of a washing machine! And, with extra layers of blasting mats, the noise measured was softer than the trains passing by.
