East River Pontoon Bridge

February 20, 2018

Could an East River pontoon bridge be a viable L train alternative?

Real estate investor, sailing champion and former Calvin Klein underwear model Parker Shinn has entered the impending void of the dreaded L train shutdown scheduled for April of 2019 with a new alternative. The concept, which joins a growing list that includes a gondola, an inflatable tunnel, car-free bus lanes, bike lanes and a lot of MTA re-routing, is called L-ternative Bridge, and consists of a temporary pontoon bridge between Brooklyn and Manhattan that would be capable of supporting two lanes of bus traffic and two walking/bike paths.
So what's a pontoon bridge?
