Spaghetti Junction

The Kennedy Interchange was designed by Barstow, Mulligan and Vollmer, a New York firm. Construction began in the spring of 1962 and when it was complete, the design was adequate to handle the traffic needs of the time. Henry Ward

. At that time, Henry Ward, who would later become the state Highway Commissioner from 1960 to 1967, stated that "downtown Louisville felt it would be disastrous for it to be bypassed by the interstate." There was tremendous pressure from both sides to push the interstate highway system through downtown. Later on in 1996, he reflected back and stated that, "... it was a mistake. I think downtown Louisville would have been better off if Interstate 65 had not been located where it is."

However, traffic was not as bad then as it is now. The projections for traffic was nowhere close to 300,000, or what passes through the Kennedy Interchange that was only designed for a maximum capacity of 100,000.

In 1996, the Ohio River Major Investment Study suggested rebuilding the Kennedy Interchange at a cost of $120.5 million. It stated that during rush hour, traffic congests at the interchange causing pollution and creating potential accidents since it has a high crash rate. From 1996 to 1998, there were 261 crashes for every 100 million miles traveled within the Kennedy Interchange, 172% higher than the state average. The study recommended that two new bridges be constructed, one downtown and one linking the two segments of I-265

 crossing by 2020.

The new downtown span and the redesigned interchange will be a vast change from the existing setup.

Changes slated for the Spaghetti Junction, Downtown Bridges Project:
  • I-64 will feature two lanes in each direction rather than being funneled into one lane.
  • Dedicated lanes for I-64 will allow motorists a sweep through the junction rather than having to take an exit from the highway.
  • Left-lane exit ramps will be eliminated. The new junction will use flyover ramps.
  • There will be no weaving segments of the redesigned junction.
  • Crossing multiple lanes of traffic to switch from I-71 to, for example, I-65, will be eliminated with new dedicated lanes.
  • Widening the shoulders to 12 feet.
  • 94 bridges will be rebuilt.
  • Improve over 28 miles of interstate highway.
  • Converting Mellwood and Story Avenues from one-way to two-way streets. This will slow traffic at these new development hot-spots.
  • Constructing a full interchange at Mellwood Avenue, which will be the new entrance into downtown Louisville

    . There is currently a half-interchange at Mellwood Avenue. Mellwood Avenue would also be widened to the south, costing $20 million and demolishing several businesses. Widening would not occur to the north due to historic shotgun residences.
  • Removing the 3rd Street exit ramp from I-64 to reduce the number of highway lanes over Waterfront Park

    .
  • Constructing exits onto River Road near Witherspoon Street to act as a new access point for downtown.
  • Building new I-65 overpasses in the downtown at Brook, Floyd and Chestnut streets to make the spaces beneath brighter and more attractive to pedestrians and bikers. New landscaping would also be placed.
  • Adding a new interchange along I-71 for Frankfort Avenue, creating a new access point for Butchertown.


The new Kennedy Interchange project will take 15 years to complete as more than 90 overpasses will need to be constructed. Along with that, three new sections of interstates that carry a very high volume of traffic will need to be reconstructed. Engineers will be required to maintain traffic through the junction.

Downtown access points will change considerably as well. Instead of the current interchange configuration at Third Street, it will be relocated to an exit at River Road near Witherspoon Street and Mellwood. This will considerably reduce the number of traffic lanes over Waterfront Park. Currently, seven lanes stretch for 154 feet over the Great Lawn; the preliminary plans call for 12 lanes over the Great Lawn totaling 318 feet.

Coming up:
  • Spaghetti Junction project (Section 1, Kennedy Interchange) will be eight sequential construction phases spanning 17 years.
  • Right-of-way acquisition plans are to be complete by late 2006.
  • Minimizing the impacts on Waterfront Park, Extreme Park and historic neighborhoods such as Butchertown
