Heading west from Flushing there is a wonderful bike path on the Queens Waterfront Greenway towards LaGuardia Airport. It ends before the airport at 27th avenue.
In this location I observed of largest urban planning fails in New York City. Billions were spent on a renovation of LaGuardia airport but the designers neglected to think people might want to exit the airport to the east on foot. There are giant no tresspassing signs, and a cut out in a fence where pedestrians and cyclists were entering and exiting the airport.
Here is a video I made showing how employees use this cutout in a fence to enter and exit terminal C.
It seems like this location would be perfect for bike/ped entrance to the airport but the Port Authority decided it was more important to focus on cars getting in an out of LGA than think about workers or cyclists. This entrance should be inviting for people, not an afterthought to the airport renovation. Port Authority, you can do better!
From the Port Authority's website on biking it says:
LaGuardia Airport
