After visiting the Arch, we went down to the riverfront to board the Tom Sawyer for a one-hour Riverfront Cruise. From the Mississippi River, we were able to get some really nice views of the Gateway Arch.
The Eads Bridge across the Mississippi. This is the oldest bridge over the Mississippi and was designed and built as one of the first steel bridge structures.
The paddlewheel of the Tom Sawyer. It's not clear how much work this paddlewheel was actually doing, or if it was simply for decoration.
The I-70 Bridge over Mississippi River is now called the Stan Musial Veterans Memorial Bridge. It opened to traffic in 2014.
