KY 40 over Paint Creek and Barnett Creek

Johnson County, Kentucky

The project consisted Phase I and Phase II design and provided for two adjacent bridge replacement projects. Due to the short distance between the two structures, they were developed as one project. Alignment and grade studies were performed and the hydraulic design was coordinated with the Corps of Engineers who was responsible for control of the dam. Both Barnetts Creek and Paint Creek are considered environmentally sensitive creeks and design of the project took into consideration the project’s impact on these streams.

The bridge over Paint Creek consisted of a three-span, 20m-32m-29m curved bridge with a gutter-to-gutter width of 12m. The bridge was skewed 41° to the long chord and designed continuous for an HS25 live load. Bridge hydraulics were especially significant due to crossing being approximately 1500’ downstream of Paintsville Lake. The crossing of Barnett Creek required design of a double 4.3m x 3.4m reinforced concrete box culvert with special wings and inlet details to accommodate hydraulic design requirements.
We were also responsible for all surveying, roadway plans, right-of-way plans, and right-of-way plans for utilities.
