Ottawa's Airport Parkway crossing may be the world's loneliest bridge.

The incomplete pedestrian and bike-friendly pathway was conceived in 2008 as a way to connect the city's Hunt Club community with the South East transit way.

It has since been subject to significant cost overruns and construction delays up to three years longer than originally projected.

It now sits sad, alone and unfinished, like the Edward Scissorhands of bridges.

With the City of Ottawa having tabled a scathing report on the project, the fiasco has spawned @AirportBridge, which may be the world's saddest Twitter account.

Its tragic, yet humourous tweets generally revolve around themes of loneliness and isolation.
