The Kentucky Transportation Cabinet (KYTC) says a unique interchange in Paducah is delivering safer, more efficient travel.
A recent analysis of the Double Crossover Diamond (DCD) at U.S. 60 and Interstate 24 (Exit 4) shows the design is reducing crashes and improving traffic flow. Completed in 2019, the Paducah DCD was the first of its kind in KYTC District 1 and only the second built in Kentucky.
Located in a high-traffic commercial area with restaurants, retail, and the Kentucky Oaks Mall, the interchange connects thousands of drivers daily. KYTC engineers say data collected over five years confirms the DCD is making a difference.
Comparing crash reports from the five years before construction to the five years after:
+ Injury-related crashes dropped 28.5%
+ Total injuries declined 32.4%
+ Overall collisions fell 3%
KYTC District 1 Chief Engineer Kyle Poat said the results reflect the built-in safety improvements of the DCD design, which helps manage speeds and smooth traffic flow.
While engineers hoped for a larger drop in total crashes, Poat called the significant decline in injuries a clear success. He said the interchange is part of KYTC’s broader SAFERoad Solutions strategy and that similar intersection upgrades could lead to even better outcomes.
Engineers continue to monitor the interchange and nearby intersections at New Holt Road and Coleman Road, making adjustments as needed. After the DCD opened, signage and pavement markings were updated to improve ramp traffic, and KYTC continues to work with law enforcement and local partners on future safety enhancements.
The DCD design uses two signalized intersections to shift traffic to the opposite side of the road, eliminating left turns across oncoming lanes. Drivers return to the correct side after passing through the interchange. This reduces conflict points, encourages lower speeds, and helps prevent serious crashes.
Roughly 28,000 vehicles use Paducah’s DCD each day.
