Motorists should be aware of an increased law enforcement presence along Interstate 26 during a hurricane evacuation exercise Tuesday, state troopers said.
Officers will be parked on the roadside during the drill from 8 a.m. to 3 p.m. from the I-26 interchange with Interstate 526 in North Charleston westward to Interstate 77 near Columbia.
The exercise will simulate a lane reversal, or contraflow, in which westbound traffic would use both the westbound and eastbound lanes during an evacuation of the Charleston area before a hurricane's landfall.
Traffic will not actually be reversed during the drill, but the S.C. Highway Patrol said motorists should be extra cautious because officers will be stationed along the shoulder of I-26.
The hurricane season officially began Sunday and will last until Nov. 30.
Also Tuesday morning, motorists should expect a delay because of a traffic crash that closed one of two lanes on River Road on Johns Island.
The Charleston County Sheriff's Office said around 7:20 a.m. that the wreck had caused tie-ups near Brownswood Road.
The intersection is halfway between Main Road and Maybank Highway.
Motorists should use extra caution in the area, deputies said.
