What if… the Christchurch Canal had been built?

The Christchurch Canal was an unrealised plan to create an inner-city shipping port.

The southeast of Christchurch might look very different today had the Canal, proposed by Cyrus J.R. Williams in December 1905, been built. Although there was significant support for the scheme at the time, ultimately it was decided to expend the funds on improvements to the Lyttelton Harbour instead.



About this map

This map poses a hypothetical perspective of the canal in the present day as it might have been completed, with the redirection of Linwood Ave, Ferry Road and the State Highway to the Port Hills, and an alternate route to Sumner.
