It may not have been intended as such, but we will “claim” this large rock core on the Mississippi River as a “geotechnical monument”. At the site of the new I-70 crossing over the Mississippi River in St. Louis, one of the 11-foot diameter limestone rock cores retrieved from one of the rock sockets drilled for the bridge foundations has been placed on the river bank along with a sign. Our own David Graham stopped by and had some pictures taken when on a personal trip their last year. So, the next time you are in St. Louis, look for the big hunk of rock on the west bank (St. Louis side) near the new bridge north of the Arch.
The new I-70 Mississippi River Bridge in St. Louis, Missouri is moving along and getting noticed in the news. Here are a couple of (somewhat) recent articles:
You can get real-time updates of the construction from three web-cams at this link. As I type today, the site is covered in snow. Very beautiful, unless you are trying to build a bridge on time!
The project page also has photo galleries and other neat stuff.
