The barely six-month old Capitol Visitor Center experienced a drainage system failure last night thanks to several days of strong storms, leading to a flooded hallway, the Post reports. The incident is described as not having caused significant damage, but it’s not exactly a great sign that storm drain equipment is already failing in the massive (and massively overbudget) $621 million underground facility. The center is open as normal today, as the flooding occurred in an area of the structure that is not part of the visitor tour.
