Montreal - an island - it's bridges

Montreal is an island, meaning there are bridges... and more bridges.

Here is the Velo Quebec web page on bridges and other forms of crossing rivers- link.

Here is blog entry last year where I discuss Montreal bridges - link.

Here I discuss some of the pecularities of cycling across the Pont Jacques Cartier bridge, because there's not much in the way of maps or bike-path-connections at either end. link

In the summer you have ferry options to cross the river. Many ferry options. The velo quebec link above also discusses ferries (traversiers in french).
