Labor Day marks the unofficial end of summer and it led to weekend visitors making a mad rush to get back home.
Grand Strand and Pee Dee highways were packed with holiday weekend travelers on Monday.
U.S. 501 heading west out of Myrtle Beach resembled a slow moving parking lot.
"Just dealing with it, it's slow but steady sometimes," said Donald Pastor, who was heading home with his family to Augusta, GA.
The South Carolina Department of Transportation did what it could to help ease the congestion.
DOT used tweets, text alerts and message boards to warn drivers about the traffic and advise them to use alternate routes.
Drivers gave mixed reviews on whether all of that did any good.
"(Traffic) seems pretty tight right now, but we may just make it through here. I'm worried about this guy behind me, though," said Todd Allen of Charlotte, NC.
It wasn't just a heavy travel day on the roads.
Myrtle Beach International Airport saw a good number of travelers, too.
Many of them said the holiday weekend traffic did nothing to diminish a fun weekend.
"Southern hospitality was about as true as it could be and, yeah, we're definitely going to be back. This was our first time down here," said Ryan Kohlhoff of Watertown, WI.
SC Highway Patrol says it's been a safer summer than last year, with a 16 percent decline in traffic deaths in South Carolina.
The Department of Public Safety is reporting 13 people have lost their lives on state roads so far this holiday weekend, which is about the same as last year.
