In Chattanooga Tennessee, an overpass for the SR153 route was demolished at the weekend using a fleet of excavators fitted with hydraulic worktools. The work was carried out during an overnight possession during which traffic was halted, with the highway then able to open again in the morning. A new overpass will take the traffic in place of the old structure.
