FREDERICK, Md. — At 10 a.m. Wednesday, the Maryland State Highway Administration closed the ramp from South Street to eastbound Interstate 70, as well as the left lane along eastbound I-70 near South Street in Frederick County, to repair a sinkhole which developed in the median about 1,000 feet east of the bridge over South Street.
Motorists wishing to enter eastbound I-70 from South Street will be detoured to make a right onto Monocacy Boulevard, then right onto East Patrick Street to the light at the ramp for eastbound I-70.
Crews are excavating around the sinkhole and filling the void with stones and concrete. The ramp and left lane are expected to reopen by Thursday’s morning rush hour, weather permitting.
The hole, about 20 feet deep, was discovered Tuesday. SHA engineers monitored the sinkhole overnight. The hollow underground area appears to be about 10 feet wide by 10 feet long.
Motorists traveling along eastbound I-70 should anticipate delays and consider alternate routes, especially during afternoon rush hour.
