Establishment Creek Bridge - replacement
Posted September 28, 2007, by Andy Meyer (andrew [dot] meyer [at] modot [dot] mo [dot] gov)

You are correct that this bridge is scheduled for replacement in 2009. The pictures attached below illustrate the damage to the structure from overdimension loads and general deterioration with age. The last two photos are attached to illustrate the condition of the rock bluff under the south abutment. If you look closely in the two photos you can see the variance in color in the horizontal layers. Some of the layers have variances in density and durability in addition to color. Unfortunately there is a soft layer very close to the normal flow of the creek directly under the bridge, which results in an abutment that will eventually be undermined by the creek. The bridge will be removed and replaced at the same location. The new south abutment will be approximately 20 feet further back to accomodate long term erosion of the bluff. The 50 people that attended the public meeting were unanimous in their desire to see a new bridge that is wider than the current 20 foot deck. The new bridge will be 32 feet in width.
