Lewis and Clark Viaduct (I-70)

The Lewis and Clark Viaduct is a series of nine bridges that span over a half mile of land and water in Kansas City, Kansas. The Viaduct provides a vital link for I-70 across the Kansas River and connects Kansas City, Kansas to Kansas City, Missouri. American Bridge was selected to remove and replace a 0.58 mile stretch of westbound I-70 from the KS/MO state line to Fairfax District Kansas City, KS. The scope of work includes demolition of the existing bridge, drilled shafts and H-piling foundations, cast-in-place (CIP) substructure, supply and erection of nine plate girder spans, 11 precast girder spans, and the CIP deck.

American Bridge’s in-house engineering developed the erection means and methods for the girder spans. The project includes erection of spans over an active railroad. In coordination with the railroad, AB developed an erection sequence to maintain active rail traffic while maintaining the project schedule.
