U.S. 17 North to Mount Pleasant backed up after Vice President Joe Biden's visit

Traffic backs up in the northbound lanes of the Arthur Ravenel Jr. Bridge Tuesday afternoon.

Vice President Joe Biden left the Lowcountry in a motorcade of black SUVs but a major traffic jam remains on U.S. 17 in Mount Pleasant.

Biden, who visited Sullivan's Island for a $10,000-a-plate fundraiser this afternoon, headed back west on closed roadways about 4 p.m.

The northbound lanes of U.S. 17 were still packed an hour later as rush-hour traffic started to fill the roads. There is also a wreck in the southbound lanes of the Ravenel Bridge on the Mount Pleasant side.

Motorists also reported delays on Interstate 526 near Daniel Island.
