CSX Transportation has come to an agreement with the S.C. Department of Transportation to pay to replace the Moncks Corner bridge that was knocked out by a train following a derailment last month.

Carla Groleau, a spokesperson for CSX, confirmed the agreement had been made but did not return a request for further details Friday. Neither CSX nor DOT would say how much the new bridge might cost.

Construction is set to start in early June, and the new bridge must be finished by Oct. 25, DOT spokesman Pete Poore said Friday. Four design teams will bid for the contract, which will be awarded June 3. The contract will include an incentive for finishing the bridge before the Oct. 25 deadline.

Last month state transportation officials told The Post and Courier replacing the 110-foot bridge would cost $2 million. Poore had earlier said the federal government had given oral approval to fund 100 percent of the construction costs. He referred inquiries concerning the cost of the new bridge to CSX Friday afternoon.

Four empty railcars in a 72-car train slipped off their track at about 30 mph and plowed into the concrete holding up Cypress Gardens Road on April 28.

A suit was filed against CSX in Berkeley County on May 15 by drivers affected by the bridge closure. The suit began with a handful of plaintiffs and is now up to more than 200, according to attorney Chris Biering.

Several people who traveled the bridge regularly for work, school, business or recreation now have to drive a more circuitous route, costing them time and money in travel, the complaint stated.

The suit alleges the train derailment was caused by negligence.

The complaint is calling for CSX to pay for damages and a daily penalty that amounts to between $5 and $20 to each plaintiff.
