A hurricane evacuation drill on Tuesday will test lane reversal plans for Interstate 26 and roads in other areas of coastal South Carolina.

The exercise will happen on I-26 from Interstate 526 in North Charleston to Interstate 77 near Columbia.

Lane reversal transforms I-26 westbound into eastbound lanes, which makes the interstate a one-way highway out of the area.

No traffic lanes will actually be reversed during the test from 8 a.m. to 5 p.m., which is not expected to interfere with traffic flow, according to the state Department of Public Safety.

Intersections will not be blocked, and motorists will be allowed to move freely, officials said.

The S.C. Highway Patrol cautions travelers on I-26 to use caution and be aware that law enforcement officers and state personnel will be located on the shoulder of the highway and at exits.

Aerial units from SLED, the Civil Air Patrol, the South Carolina National Guard, the state Department of Natural Resources and the state Forestry Commission will be flying surveillance routes. The state DOT will also deploy incident response vehicles.

Other roads affected by the drill include U.S. highways 21 and 278 in the Beaufort and Hilton Head Island area, and U.S. Highway 501 and S.C. Highway 544 in the Grand Strand area.

Hurricane season began June 1 and ends November 30.
