New York Monorail Lines Under Construction — Active Extensions and New Monorail Routes

New York monorail lines currently under construction. Active extensions, new monorail routes and network expansion projects.

New York 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.

New York currently has 12 railway segments under construction including 8 railway and 4 metro.
