Two 12-Foot Driving Lanes with 10-Foot Outside Shoulders and 8-Foot Inside Shoulders

The Oklahoma Department of Transportation (ODOT) contracted with Cabbiness Engineering and its design team to replace the structurally deficient and functionally obsolete US-64 Bridge over Big Sallisaw Creek in the year 2014.

The intention was to construct a new bridge structure and new roadway segment on an offset alignment to mitigate any construction impacts to the city park adjacent to the project site and to accommodate future divided roadway improvements.

Cabbiness Engineering and its design team provided design services for the replacement of the new multi-span bridge constructed on offset alignment south of the existing US-64 alignment. Inclusive with the bridge design, were the replacement of two bridge box structures that conveyed tributary creeks and acted as overflow structures for the main Big Sallisaw Creek. The roadway section was designed to accommodate the eastbound lanes of US-64 if the roadway were to ultimately become a fully divided roadway section in the future.

The new roadway consists of two 12-foot driving lanes with an outside shoulder of 10-feet and an inside shoulder of 8-feet.

The tasks Cabbiness Engineering and its design team are responsible for are as follows:

  • Conduct a detail topographical survey of the existing conditions

  • Prepare detailed roadway plans

  • Perform hydrologic and hydraulic calculations for all bridge structures and roadway structures

  • Prepare detailed bridge plans

  • Prepare and submit comparative cost estimates

  • Prepare a detailed construction sequence and phased construction plan

  • Prepare pay quantities with supporting design calculations

  • The project’s design criteria followed the current ODOT Design Manuals for both the roadway and bridge aspects and supplemented by the 2010 AASHTO “Green Book” criteria in the areas to be widened, reconstructed and resurfaced.
