Open publisher page 0 citations

Abstract

Currently the longest span arch bridge in the world is the Chaotianmen Bridge in Chongqing, China, with a main span of 552 metres. Recently there have been several proposals for much longer span arch bridges but these have yet to progress to design and construction. This paper reports on a pilot study to assess the feasibility of constructing an arch bridge with a main span of 750 metres.
