Project Description

Leavenworth County Bridge

The Leavenworth County Route 92 Centennial Bridge was built in 1955 and connects Leavenworth, Kansas, and Platte County, Missouri. The bridge is jointly owned and maintained by the Kansas and Missouri Departments of Transportation.

In 2011, AOG was hired as part of a multi-team approach to widen the bridge and improve critical structure fatigue. We provided early-construction drilling and engineering, mid-construction materials testing, and special inspections during roadbed construction and roadway/approach slab replacement.

Repairs were made to bridge piers, bearings, drainage, and other structural components in order to extend the life of the bridge while KDOT continues to examine options for constructing a new four-lane replacement bridge. A total of 14,000 vehicles use the structure daily.

Bridge length: 2,571.2 feet
Longest span: 419.8 feet
