Anyport is a model developed by Bird (1963) describing how port infrastructures evolve in time and space. Based on his research into the evolution of British ports, Bird proposed a five stage model to demonstrate how facilities in a typical port develop. Starting from the initial port site with small lateral quays adjacent to the town center, the elaboration of wharfs is the product of evolving maritime technologies and improvements in cargo handling. This is also marked by changing spatial relationships between the port and the urban core, as docks are built further away from the central business district. In the final stages, increased specialization of cargo handling, growing sizes of ships, and ever increasing demands for space for cargo-handling and storage results in port activity being concentrated at sites far removed from the oldest facilities. Port infrastructures are thus constructed over several decades and in some case over several centuries. Three major steps can be identified in the port development process identified by Anyport:
