The OTA studied the area where the new interchange will be built at I-44 and SH-37. Here is what they found:

• Relocations: Approximately 6 homes and 22 businesses in the project area will be purchased by OTA. OTA is currently working with the property owners to complete these purchases and assist with moving costs. 

• Historic and Archaeological Resources: Experts walked the area and dug small holes to look for archaeological items. They also examined all of the buildings and structures 45 years of age and older to evaluate their historic significance. No significant historic or archaeological resources were identified. These results will be reviewed by the Oklahoma State Historic Preservation Office.

• Aquatic Resources: Biologists mapped all of the streams, ponds, and wetlands in the area. One stream, which flows into Pond Creek, will require a permit from the US Army Corps of Engineers for construction of new culverts.

• Protected Species: The project may affect habitat for the bald eagle, whooping crane, piping plover, and Arkansas River shiner. A bald eagle survey will be completed prior to construction and any active nests will be avoided. Certain activities such as fueling and storage of materials will be restricted within 300 feet of the Canadian River. The US Fish and Wildlife Service has agreed with these protection measures.

• Hazardous Materials: There are several underground fuel storage tanks in the project area; however these are not anticipated to affect construction. If workers find contaminated soils during construction, they will stop work and follow procedures to protect the health and safety of people and the environment.

• Farmland: The project will affect approximately 79 acres of farmland. The Natural Resources Conservation Service has determined that these impacts do not require any additional action.

• Noise: A noise study was completed according to FHWA and ODOT policy. Noise impacts were identified at six homes. Noise walls were considered, but these walls would not reduce noise enough to meet goals established in the ODOT Noise Policy and will not be included in the project.

Once everything is approved, the studies and public comments will be put together in a final report for review and consideration for approval by FHWA.
