JDQ has been in the civil engineering design and survey business since 1936, 66 years and is currently active in both Kentucky and Illinois. The firm's experience stretches from early projects with gasline and oilwell companies and Owensboro subdivision developments to the design of a section of the original Kentucky Turnpike and on to various toll roads, resource recovery roads, interstates and the upgrading of I-65 to six lanes in Hardin County, including re-design of the interchange with the Western Kentucky Parkway and US 31W. A person can travel very few miles in any direction in Kentucky without crossing a portion of a roadway or structure designed by JDQ. The firm has designed sections of I-75, I-65, I-64, I-71, most parkways, KY 80, AA Highway, and the Pikeville Model Cities Program (US 23 was placed on a bench of the mountain-cut used to re-route the Big Sandy River away from Pikeville); and in Illinois I-55, I-155, and IL 336. Our work also includes Bypasses at Owensboro, Bowling Green, Hopkinsville, Hardinsburg, Cloverport, Peoria IL and Waterloo IL. For the latter project JDQ received the Illinois Department of Transportation’s 1998 Award for Exceptional Engineering Service for Rural Highway Design.

As well as large highway projects our personnel have designed industrial perimeter roads, county road relocations for mining purposes, city streets, county road spot improvements for grade and curvature, bike paths, street widening and bituminous overlay plans.
