The Oklahoma Department of Transportation (ODOT) desired to provide safety improvements to segments of the US-75 roadway section beginning approximately seven and one-half (7.5) miles north of the US-75/US-62 Junction in Okmulgee, north approximately four and seven tenths (4.7) miles in Okmulgee County. The project was located between Preston and Winchester in rural Okmulgee County. It was ODOT’s intention to improve the existing median openings and roadway deceleration lanes of US-75 based upon the current ODOT Roadway Design Manual 3R design criteria where applicable. Where reconstruction of the existing roadway section was necessary, the 6th Edition of A Policy on Geometric Designs of Highway and Streets (the AASHTO Green Book) design criteria was utilized. One of those locations where reconstruction was needed was the intersection of US-75 and EW-90 (Will Sampson Road in Preston). There were median cable barriers along this segment of US-75 that needed to be adjusted and/or relocated to accommodate the new median opening designs. Additionally, a review of the median opening locations, geometric hazards such as stopping sight distance issues or intersection alignment issues were evaluated.
