EST, Inc. (EST), is proud to announce the addition of Gary Ridley, PE, to its experienced team of project managers and engineers.

Gary spent 48 years of his illustrious career with the Oklahoma Department of Transportation (ODOT) and the Oklahoma Turnpike Authority (OTA), serving as the Director of ODOT for 12 years, Director of OTA for 4 years and Cabinet Secretary of Transportation for 8. He has extensive experience in planning, designing, and delivering major transportation initiatives and projects in Oklahoma, working extensively with cities, counties, state entities, and private contractors to effectively manage comprehensive projects and handle crisis situations.

During his tenure as director of ODOT, he oversaw the reconstruction of the Arkansas River Bridge on Interstate 40 that was knocked down by a runaway barge that killed 14 people. This $30 million dollar emergency detour and interstate bridge replacement project was completed in 64 days from the time of the accident until the opening of the bridge. As Director of OTA, Gary was able to increase capacity on 14 miles of urban turnpikes. This $130 million dollar initiative added additional lanes in each direction on the turnpikes in Tulsa and Oklahoma City and only took 18 months to complete.

In the fall of 2015, Secretary Ridley along with the Director of OTA, initiated a $900 Million dollar turnpike expansion that would include over 35 miles of reconstruction and increased capacity (additional lanes) of existing turnpikes. The expansion also includes the construction of 29 miles of new urban turnpikes as well as nine new interchanges in the metro area of Oklahoma City. These projects are well underway and are scheduled to be completed in early 2020.

Gary retired from his position as Director of ODOT and OTA in 2013 but continued to serve as Secretary of Transportation until 2017.
