Project Description: This project was designed by Johnson, Depp & Quisenberry in two stages. The first contract called for studies for location and grade on 3.7 miles of roadway and design of a two-lane initial and four-lane ultimate facility with right-of-way being acquired for the ultimate design. The project was a rural project providing a bypass on the southwest side of Hopkinsville between US 41A and KY 695 with a crossing at KY 107 about the middle of the project and an at-grade crossing of a railroad owned by the US Army. There were three bridges and two box culverts designed by the Consultant. After design was completed and plans were turned in and accepted by the Department, the decision was made by the State to include the easternmost 1.9 miles (from US 41A to KY 107) in the upgrading of US 68. Johnson, Depp & Quisenberry received another contract to redesign this portion of the roadway to a four-lane divided facility. More right-of-way was required because the median was widened to correspond to the US 68 Typical Section. Two bridges and one box culvert were revised for twin structures on the bridges and extended length on the box culvert. The railroad crossing was redesigned and median inlets were added to accommodate the depressed median.

The Consultant was responsible for:

1. Securing aerial for alignment studies and right-of-way strip maps.

2. All alignment and grade studies for location.

3. A planning report providing documentation of the selected corridor.

4. A Design Study Report defining design features of the project.

5. All necessary field surveys.

6. All cross sections were field run.

7. All necessary office work to provide Preliminary Line and Grade Inspection Plans, including proposed right-of-way.

8. A Design Executive Summary with typical sections for approval.

9. Geotechnical Investigation.

10. All necessary field and office work to provide grade,

drain and surfacing plans for construction of the project.

11. Right-of-way plans and right-of-way plans for

utilities and related services, including deed

preparation for each parcel.

12. Preparing drainage situations and calculations

and compiling drainage folders for the project.

13. All structure design.

The Department was responsible for:

1. Traffic movement volume projections.
