Abstract:River-crossing transportation is the main factor supporting the river-crossing development of city. The reasonable layout and the construction mode of river-crossing channel have become the key of urban river-crossing transportation. Combined with the current development situation of river-crossing transportation in Shanghai, the key issues in the planning and construction of river-crossing transportation are expounded from two aspects of river-crossing transportation layout and the channel construction. Through the related case analysis and network modeling analysis, the river-crossing channel scale has the stronger correlation with the river width in addition to city scale. In the construction aspect, the multi-channel dispersed river-crossing mode and the multi-connection mode have the obvious superiority, which hopes to provide experience, reference and reflection for planning and construction of urban river-crossing transportation.
