Two events held at MetLife Stadium caused a traffic backup Wednesday night.

The U2 and Lumineers concert was held while the State Fair Meadowlands was going on.

This resulted in heavy traffic delays around the stadium, as well as crowded train stations in the area.

Several concertgoers posted on social media that they were stuck in traffic and were afraid they were going to miss the concert.

Anyone who is attending the second night of the concert or the state fair Thursday should also be prepared for heavier traffic.
