Update: Traffic is moving smoothly as of 4 p.m. Friday.
Drivers headed south to Cape May for the weekend be aware. Traffic on the Garden State Parkway south is backed up over 2 miles before Exit 30.
The backup is due to construction on the Greater Egg Harbor Bay bridge.
Northbound traffic is also expected to back up later Friday and could see increased wait times for the next few weeks. As part of the construction project, one lane will be shutdown until Oct. 20.
