Commuters hit the brakes in both lanes, and scooped up the money.

The traffic jam in the tunnel ended up lasting eight hours, WRC reported.

Now police are trying to find the free money.

Maryland Transportation Authority Police said that anyone who took the cash, and didn't yet give it back, can turn it in by a Saturday deadline and they won't charged with theft.
