Abstract:

Widening and reconstruction of the Kennedy-Bridge in Bonn, Germany.

The Kennedy-Bridge is situated in the centre of the city of Bonn and spans the river Rhine in the course of the federal road B 56. The Rhine-Bridge has been made wider from 18 m to 26.80 m and has been completely reconstructed from the beginning of the year 2007 till autumn 2010. For this a broadening of the rivet-construction of the year 1949 resulted in two identical extensions of an extra welded girder with a length of span of 99.22 m - 195.86 m - 99.22 m. The hight of the construction comes to 11.50 m over the two current piers and 3.40 m over the main opening. The existing roadway made of barrel-metal sheets and topping slabs has been reinforced by longitudinal ribs and cross girders and widened by the extension of an orthotropical plate. The old construction has been stiffened by big expenses with the aim of fulfilling the demands of the current standardizations. The Kennedy-Bridge is the only Rhine-Bridge in the City of Bonn; therefore the traffic and the tramways have had to be maintained during the construction period.
