MacArthur, Cobb, Poe & SAIC Honored as

Engineering Excellence Award "Grand Conceptor" For

Crosstown Expressway Relocation Project


The design team of MacArthur Associated Consultants, Cobb Engineering Company, Poe & Associates, and SAIC were honored at the January 24th ACEC OKLAHOMA  Engineering Excellence Awards presentation with the Grand Conceptor Award as Oklahoma's  best engineering project in 2012.


The I-40 Crosstown Relocation Project unknowingly spurred the renaissance of Oklahoma City.  This pivotal project positively impacted the Oklahoma economy and brought a diverse community together through a shared vision.  The Interstate 40 section from the I-235/I-35 interchange, west 6 miles to Meridian Avenue, known locally as the Crosstown Expressway was originally constructed in 1965.  The decision was made to relocate the I-40 Crosstown approximately 4 blocks from the existing location forever changing the face and direction of Oklahoma City.


Downtown Oklahoma City was the picture of inner-city blight. A once thriving city center, by the late 1980’s downtown was losing its business base to the suburbs and had lost its nightlife completely. I-40 formed a barrier on Downtown Oklahoma City’s southern edge, splitting the city’s core from the North Canadian River and the population beyond.  In November 1989, at the same time civic leaders and politicians were meeting on ways to breathe life into the City’s dying downtown, a crack was discovered in a pier beam on an elevated portion of the highway. These seemingly unrelated events would lead to a downtown Oklahoma City renaissance.


This project began a monumental movement including the City of Oklahoma City’s Core to Shore urban redevelopment plan including a Central Park, MAPS 3, the development of the Boathouse District along the Oklahoma River, Devon Tower, Project 180 and an NBA basketball team – Our Oklahoma City Thunder.


Each Design Partner portrayed flexibility, complex design knowledge, and collaboration in order for their innovative and sustainable design practices to come to life in this extensive project.
