DelDOT needs to close Silver Lake Road in Middletown to make dam repairs.

Silver Lake Road will be closed today (July 21) until Sunday (July 23) in Middletown to make dam repairs, said the state Department of Transportation.

DelDOT’s contractor, Mumford & Miller Concrete, will be installing a temporary steel sheet pile cofferdam which will allow the lake to return to its normal water level.

The cofferdam will stay in place until the spillway/gate system is replaced, which will be at a later date.

Detour signage is posted for motorists.
