This was the largest overall project ever undertaken by the Oklahoma Department of Transportation (ODOT). The entire project relocated the existing I-40 facility through Central Oklahoma City, extending from I-44 to I-235, a distance of approximately 3.5 miles. The new alignment was approximately 5 blocks south of the existing route, and features 10 through lanes. The total estimated cost of the overall project was approximately $360 million, which includes engineering design, construction, right of way acquisition, and utility relocations.

Poe designed a 1.2-mile section of this project, extending from west of Exchange Avenue to east of Shields Boulevard. Our design included 11 roadway bridges, four railroad bridges, extensive retaining walls, relocation of two mainline railroads and several local railroad connections, extensive major drainage features with numerous associated large structures, consideration for significant local groundwater conditions, extensive environmental issues, and inclusion of aesthetic features on all structures. All design work was accomplished under an accelerated schedule.

Construction Cost – $170 million
