Renovated Bascule Bridge Reopens in Chattanooga

This article describes the renovation of the Market Street Bridge in Chattanooga along the Tennessee River. The double leaf steel truss bascule span, completed in 1917, has three symmetrical arch spans of concrete on either side. The renovation is important as the substructure of the nine approach spans of the bridge had been severely deteriorated and so were replaced down to the footings. Four cast-in-place girders were also replaced on the bridge with prestressed box beams that are superficially identical to the originals. All of the mechanical aspects of the bascule were overhauled as well, which now operates as a Scherzer rolling lift bridge, although locks along the Tennessee River have largely obviated the need for bascules. The renovated structure how carries four lanes of traffic in addition to pedestrians.
