CRANFORD - The Memorial Day weekend officially kicks off Friday, but trips have already started for some hoping to beat the rush.

Weather and construction have already affected traffic on the New Jersey Turnpike.

AAA says more than 800,000 drivers are expected to hit the roads this holiday weekend. Spokesperson Tracy Noble says over 90 percent of those traveling will be on the roads. This doesn't include visitors from Delaware, Pennsylvania and New York.

Police are asking drivers to take extra care as they travel the roadways this weekend. New Jersey State Police Captain Eric Heitmann says to look out for stop-and-go traffic and lane shifts. He also reminds drivers and their passengers to wear seatbelts and to keep children in properly installed child seats.

AAA also suggests leaving early to compensate for traffic, and to bring snacks and water.
