North America Monorail Lines Under Construction — Active Extensions and New Monorail Routes

North America monorail lines currently under construction. Active extensions, new monorail routes and network expansion projects.

North America monorail lines currently under active construction: new systems in cities or airports without an existing monorail, extensions to serve new terminals or development areas and upgrades to existing routes. Monorail construction is often chosen for elevated urban transit where surface space is limited and full metro tunnelling is cost-prohibitive.
