There are many reasons to support the Move NY Fair Plan — and the Assembly bill recently introduced that would authorize it.

If enacted, the plan will not only slash traffic inside and outside the Central Business District but generate $1.35 billion in annual revenue. The money will be used to improve the city’s roads and bridges and finance a $12 billion program to upgrade and expand the region’s mass-transit system, with a particular focus on bringing new transit service to underserved communities in places like Eastern Queens, South Brooklyn, Staten Island and the East Bronx.

Under the bill, tolls on the MTA’s seven bridges — the Verrazano, Throgs Neck, Whitestone and Triborough, among others — would be cut nearly in half. Tolls would be restored and introduced on the most congested, transit-rich crossings into the city’s core — the four East River bridges and the streets and highways that cross 60th Street in Manhattan.

In addition, the plan would ensure the relative discounts on the outer bridges would be locked in place permanently with a clause that automatically removes the new CBD tolls if the MTA raises the outer-area tolls by a disproportionate amount — which would force it to give up more revenue than it could ever gain.

Another reason to support the plan is fairness. In the current system, some drivers pay more while others pay nothing at all to use the city’s bridges. Moreover, the excess car use induced by the free crossings causes a myriad of side effects that plague all of us — from chronic traffic and additional carbon emissions to car crashes and the high pedestrian and cyclist injuries (and deaths) that go with them, to say nothing of skyrocketing asthma rates.

So who might oppose such a plan? Drivers, of course, who regularly use the once-tolled, now free East River bridges. But the two leading groups representing the state’s motorists and truckers — AAA-NY and New York State Motor Truck Association — have expressed support for the plan.

And it’s easy to understand why. Only an estimated 2 percent of the region’s daily trips will face a higher cost while 100 percent of the region’s drivers will see huge benefits: faster travel in and around the CBD, drastically lower tolls on the city’s outer bridges and a first-ever ($375 million per year) dedicated fund for maintaining the city’s pot-hole riven roads and bridges.

Plus, the plan caps the charge for small and medium-sized businesses outside the business district at one round-trip toll per day regardless of how many trips they make.

Another reason? The revenue from the plan will be used wisely — lock-boxed and spent on the transportation priorities outlined in the bill. Here’s how it works. First, unlike “dedicated” MTA taxes that have to be appropriated by the Legislature, the new toll money will go straight to a new authority and therefore cannot be “raided” by Albany.

Second, the bill establishes a legal obligation that the authority allocate the money to specific Move NY priorities: reimbursing the MTA for lost revenue on outer bridges and supporting current and future MTA capital plans; setting aside the money needed to help maintain the four East River bridges and improving other major arteries like the Van Wyck and BQE; creating an electronic toll-collection system; establishing investment funds for the city’s “transit deserts” as well as for those on Long Island and in the Lower Hudson Valley; and subsidizing a targeted fare-relief program for riders using Express Buses, Metro North and the LIRR.

The Move NY bill represents a watershed opportunity for New Yorkers to reinvest in our transportation system while substantially reducing the traffic that is choking us, literally and figuratively — our lungs, our streets and our economy, which loses an estimated $16 billion a year in lost productivity due to our inability to move goods and people. It’s time to #GetNYMoving again.
