As the message boards along Route 1 near Route 52 have doubtless informed you, Route 100 is going to be closed at the Delaware line starting at 7 a.m. Monday, Nov. 7.
According to the Delaware Department of Transportation's website, workers from Eastern Highway Specialists will be removing and replacing the concrete deck on a bridge along Route 100 (Montchanin Road) just north of Twaddell Mill Road.
The closure is expected to last until Friday, Dec. 9, depending on the weather. DelDOT suggests motorists use Route 52 (Kennett Pike) instead of Route 100 for the duration.
(In case you're interested, the state line crosses Route 100 between Twaddell Mill and Cossart Roads.)
