I've occasionally mentioned that there has been a large amount of work around and under the Arch for the last three years. Everything is done now. People used to enter underneath the legs; there was a puny museum between them. Now there is a fancy new entrance west of the monument, closer to the city itself. Outside is a circle depressed into the ground, lower as you approach the Arch. Half of the circle is covered by a glass awning. Inside, an arc of glass looks back to downtown. This lobby leads to a far larger and very well done museum.
Maybe we will have a look from above tomorrow.
