Someone needs to explain to me how a sea of people could “cross” Highway 70 which separates the Old Courthouse from the Arch grounds. There are eight (three each on either side of the two sunken Hwy lanes) between the grounds and those two buildings on either side of the “mass.”

It's the highway that's depressed, NOT Memorial Drive, which, unless the city did something completely nutty, was probably closed, just like they do for the Fair and everything else that goes on down there.
