The construction of the Cypress Gardens Road bridge that was destroyed by a train derailment about three months ago is on schedule, according to officials with the South Carolina Department of Transportation.

The project is 35 to 40 percent complete and on schedule to be finished by October, according to DOT spokesman James Law.

Crews this week were working on the embankments of the Moncks Corner road and were expected to install the girders for the bridge Friday, Law said.

In June, DOT awarded a $3.05 million emergency contract to Cape Romain Contractors Inc. to replace the bridge.

The derailment of a CSX train brought down the 78-year-old bridge on April 28. No one was injured in the accident, although a pickup truck driver was left shaken after he was forced to jump a 15- to 20-foot gap created by the collapse. The fallen bridge also severed a water main.

The destruction of the bridge created a 22-mile detour for the estimated 6,200 cars that cross the bridge daily. The detour remains in place while the new bridge is under construction.

Several drivers who alleged they've been inconvenienced and financially burdened by the detour filed a federal lawsuit in June against CSX Transportation.
