9/09/2007 This picture is a three bridge scene. To the right is the single remaining arch of the C&O Canal Catoctin Creek Aqueduct. The missing two arches collapsed in 1973. Behind the aqueduct you can see an arch of the B & O railroad bridge or viaduct. Above them is the the Bailey Bridge provided by the US Army Corp of Engineers in 1980 after aqueduct's collapse. The Bailey Bridge was built right beside the remains of the aqueduct.
