There’s a math error in that headline above - TIME added a correction:

Therefore we can estimate that commuters spend 320,850 hours going from New Jersey to New York over the bridge during a normal four-day stretch. If we assume the traffic jam doubled that time, the total cost of the jam would be $7 million. If we assume that it quadrupled commuters time on the road it could have cost as much as $21 million!

Correction: An ealier version of this post mistakenly used the total number of minutes traveled each day across the bridge rather than hours, overestimating the cost by a factor of 60. Thanks to reader Gary Goetz for pointing out the mistake!
