JACKSONVILLE, Fla. -

The Monster Jam truck competition will bring some traffic congestion downtown Saturday, and Jacksonville police are offering travel advice to drivers.

Assistant Chief Leonard Propper, of the Jacksonville Sheriff's Office, advises drivers heading to EverBank Field take take the Mathews, Hart or Main Street bridges.

He also says there will be new pickup and drop-off locations.

"It's going to be on Georgia Street, which is directly behind the Baseball Grounds between Adams and Duval (streets), and you have the opportunity to drop anybody you want off during that time prior to the event starting. The key is, you have to be back at that location by 9 p.m. in order to pick them back up."

Aside from traffic, police have another concern -- underage drinking.

Propper says a team will heavily enforce it, and anyone younger than 21 will receive a citation on the spot.
