Department of Transportation District Engineer Randy Midgett, the excavator slipped off timber mats while cleaning out many years' worth of silt from a detention pond as part of the Elizabeth Street restoration project that's replacing the causeway's metal drawbridge. Another excavator was expected to help dig out its sunken comrade, Midgett explained. He added the Elizabeth Street project will include cleaning out and slightly widening the detention pond, which will be served by three recently installed stormwater pumps. Temporary bypass pumps are in place to prevent flooding, he said.
