New Jersey has lost the battle over congestion pricing.

That means effective yesterday at 12 a.m.. You're now paying $9 each time you enter the city south of 60th Street during heavy traffic periods.

The state's court case came down to the very end.

And as senior correspondent Brenda Flanagan explains, new Jersey leaders are still promising to fight it.

321 unveiling a tall sign, the MTA's General Lieber celebrated launching the first U.S. congestion pricing toll at midnight Sunday morning, an historic moment 1400 cameras started clicking.

Docking drivers headed into Manhattan's toll zone at 110 detection points south of 60th Street.

Nine bucks a car.

More for trucks.

It's still controversial, contested and complicated.

This is a toll system like has never been tried before in terms of complexity.

It's not like when you just roll under one set of cameras on a highway.

We've got to go through a whole process where we identify.

When you came in, what type of vehicle do you have an exemption?

This is an exciting time for the New York City metro region.

The launch signals a victory for progressive advocates, capping months of raucous political protests and bitter legal battles between New York and New Jersey.

In just a few weeks, we are going to see cleaner air.

We are going to see a relief of traffic congestion and therefore better commutes for the people who do have to drive into the city.

I think it'll help clear the traffic in New York.

I mean, it's just been really bad when you try to go into the city.

I mean, I try to get to with my family once a week, and it's just so many cars.

Transit commuters like Shantell Janiero welcomed the toll, but many new Jersey drivers worry it'll take a hefty bite out of their already stretched budgets.

I think it's good because the traffic won't be as bad.

But you know, it sucks to pay more than I already was.

So I want to say this to all the hard working Jersey families.

We will never stop fighting for you.

We're going to keep fighting New York to protect your wallets and to make sure we protect our jersey values.

Congestion pricing foe Congressman Josh Gottheimer said court proceedings aren't over.

He noted a federal judge last week ruled that towns like Fort Lee need more robust protection against increased air pollution from traffic, detouring to evade the expensive new toll.

New Jersey push that angle when it asked the judge to block congestion pricing in an 11th hour appeal on Friday.

We feel the decision reflected the importance of mitigation for new Jersey communities that are going to be.

Adversely affected by congestion pricing and that.

There's a need for a pause here until those issues are resolved.

But Judge Leo Gordon refused to delay congestion pricing, ruling the plaintiffs failed to demonstrate likelihood of irreparable harm and that mitigations on the way, the judges ordered a new plan with more money and an upgrade to curb pollution in new Jersey, comparable to designs created for the Bronx.

New York has until the 17th to resent their plan.

We'll be watching every step of the way, and I want to be clear on this, whether it's today, tomorrow with the new administration or through legislation that we plan to introduce bipartisan legislation.

Let me be clear.

In New York, we'll never stop fighting this congestion tax.

Will new Jersey Democrats appeal to the president elect who's vowed to kill congestion pricing, claiming it's terrible for business?

Governor Murphy hasn't commented.

Lieber argues the tolls tailored to enhance business.

There's a huge discount on the overnight, and it's especially designed to incentivize trucks who take up so much space and create so much traffic to do more of their deliveries overnight.

For cars using E-Z pass, the tolls plunged to 225 overnight, rising to $9 from 5 a.m. to 9 p.m. weekdays, 9 a.m. to 9 p.m. weekends, and there's a $3 discount for using the link in our Holland Tunnels NJ spotlight news.org got more details?

And monitors are keeping close track of traffic patterns.

We know that the best thing to do is to turn the policy on.

See how it's working and then look for.

Do careful monitoring, look for unintended consequences, and make sure to mitigate those.

The Rpas Tom Wright says congestion pricing is working well in several cities around the world, including London, and even a small reduction in traffic can have an impact.

It's the driver who thinks they can make it across before the light changes and gets stuck in the middle of the intersection that causes the gridlock that freezes it up for everybody.

As traffic data and toll money start rolling in, folks will get a better view of the road ahead.
