Big Weekend For Emerson Bridge Construction

Cement trucks deliver their load by driving over the old bridge spanning the Mississippi River.

As one truck finishes dumping its load of cement another is backed into place to continue the process.

Dave Luther, construction inspector with the Missouri Department of Transportation, watches as fresh cement is dumped into a hopper to be funneled to a barge on the river below.

Sam Johnston, cement truck driver for Delta Concrete, operates controls on his truck regulating the flow of cement into the hopper.

A barge with hoppers full of wet cement are moved into position alongside the new Pier 4 foundation.

The hopper is then lifted via a crane above the formed in foundation. Workers then dump the concrete into the giant hole below.

Anchored deep into the bottom of the Mississippi River, the new pier will soon rise above the water taking its place in position with the others.
