Retaining wall collapses on I-575

Photos: Construction on part of a new interchange on I-575 in Woodstock came to a halt Thursday, Aug. 25, 2011, after 16,000-pound sections of a retaining wall collapsed.

Workers begin to repair a collapsed retaining wall on part of a new interchange under construction on I-575 in Woodstock after several 16,000 pound sections fell on Thursday.

The collapse of sections of a retaining wall near the planned Ridgewalk Parkway Bridge on southbound I-575 was possibly caused by a road construction roller used for grading and compacting dirt. One section of the wall landed on the roller.

At least seven of the huge sections came down.

Workers begin repairs. The collapse came about when workers were compacting the ground on one side of the retaining wall for the new interchange and several sections of the wall fell, assistant Woodstock Fire Chief Jimmy Eley said. One of the sections fell on the tractor."

The wall fell away from the roadway, but traffic was affected.

After the collapse, state Department of Transportation crews began trying to right the sections.

Work on the interchange, which is north of the Towne Lake interchange at Ridgewalk Road, began in February and is expected to be completed by December 2012.
