Keep your speed down westbound over the Intracoastal Waterway bridge as you enter Jacksonville from Atlantic Beach. JSO sets up a ticket factory there a couple of nights a month, usually on Saturdays when they can get DUI too. The speed limit is 45, but flow of traffic is closer to 60 at times. Sometimes there will be an unmarked car off the side of the road at the top of the bridge (JSO has jurisdiction throughout Duval County–they can do this) nailing you with radar, but more often there’s a van pulled off at the bottom and a uniformed officer manning a radar/laser unit. Either way, there are always 5-7 JSO cruisers pulled off in various business parking lots nearby waiting for you, and they will get you here. Not much of a cushion is given, and if you are pulled on a Saturday night, expect field sobriety tests to be administered.
