Public safety planning for the Cooper River Bridge Run is taking into account the threat represented by the Boston Marathon bombings, officials said Thursday.

Some 400 officers will be assigned to Bridge Run events April 3-5.

"A huge, huge commitment," said Capt. Thomas Robertson of the Charleston County Sheriff's Office.

The Secret Service, the FBI and the Bureau of Alcohol, Tobacco and Firearms will work the event along with city, county and state law enforcement, he said.

"This is probably one of the biggest collaborative efforts law enforcement has had working the Bridge Run," Robertson said.

Robertson and other officials briefed the Charleston County Council Public Safety Committee on preparations for the event.

"Avenues of ingress and egress not available before" are part of the Bridge Run plan, Robertson said.

Nearly 150 medical personnel from a dozen agencies will be on stand-by, said Charleston County EMS Director Don Lundy.

Getting people out of the area safely is a priority. Plans have been made for responses to a range of situations, he said, and resources will be in place that people would not expect.

"I feel confident that we are going to have a great race," he said.

An array of cameras will be used for security, including those available from the state Department of Transportation. More cameras will be placed at the start and finish lines, officials said.

Charleston County Consolidated 911 Center will have five dispatchers at the Charleston Maritime Center, officials said.

Bomb-sniffing dogs will be present. Bags issued to runners will be clear plastic. The Beer Garden is cancelled, and there will be an increased number of restricted areas, Bridge Run organizers have said.

The Bridge Run is April 5. Last year, it had more than 31,000 finishers.

Officials said security planning began nearly a year ago.
