The Watterson Expressway, I-264, loops through Louisville's west, south and east ends and connects I-64, I-65 and I-71 with major streets like Dixie Highway, Bardstown Road and Shelbyville Road. It carries commuters, shoppers and trucks, often bumper to bumper. A Watterson Expressway accident can happen fast at a merge, in a slowdown, or in a construction zone where lanes shift overnight.
Here's what the crash numbers show, what's happening with construction at US 42, who may be responsible, and what to do after a crash.
How many crashes happen on I-264?
The Kentucky State Police 2024 Kentucky Traffic Collision Facts report lists these totals for I-264:
- 1,428 collisions
- 274 people injured
- 2 people killed
Source: KSP 2024 Kentucky Traffic Collision Facts, "Collisions on Interstates and Parkways." The figures cover the whole route.
Louisville's own High Injury Network ranks surface streets only, so the Watterson isn't on it. But several roads with high-injury segments, including Dixie Highway, Preston Highway, Bardstown Road and Shelbyville Road, have interchanges with it. For statewide and county numbers, see our Kentucky car crash statistics.
Construction at I-264 and US 42 (Brownsboro Road)
The Kentucky Transportation Cabinet (KYTC) is rebuilding one of the Watterson's busiest interchanges. KYTC announced the project on July 7, 2025. According to its project page, the $130 million project:
- Rebuilds the I-264/US 42 interchange as a single-point urban interchange, controlled by a single signal
- Widens I-264 from two to three lanes in each direction between Westport Road (KY 1447) and I-71
- Rebuilds and widens the US 42 bridge over I-264
- Adds new two-lane ramps from I-264 East to I-71 North and from I-264 West to Westport Road
KYTC says the interchange "serves more than 70,000 drivers daily." During construction, KYTC says two 11-foot lanes will be kept open, with lane shifts, ramp changes and periodic closures. The project is expected to be finished in fall 2027. Check the project page for current traffic impacts.
Common Watterson crash types
- Rear-end crashes in slowdowns, especially near interchanges and lane shifts. See rear-end collisions.
- Merge and lane-change crashes at short on-ramps and exits.
- Work-zone crashes caused by narrowed lanes, barrier walls and sudden traffic pattern changes.
- Truck crashes. The Watterson connects three interstates and carries heavy truck traffic. See our truck wreck and commercial vehicle crash pages.
Who is at fault in a Watterson Expressway crash?
Usually, the driver who broke a traffic rule. A driver may not move right or left on a roadway "until the movement can be made with reasonable safety" and without signaling (KRS 189.380(1)). Where a road has three or more marked lanes in one direction, drivers must also stay within a single lane until they ascertain a move "can be made with safety" (KRS 189.340(7)(a)). Drivers must not follow "more closely than is reasonable and prudent" (KRS 189.340(9)(a)), and must not drive faster than "is reasonable and prudent" for traffic and conditions (KRS 189.390(2)), even below the posted limit. The same lane-change rules decide fault in many Spaghetti Junction accidents downtown.
Kentucky's pure comparative fault rule (KRS 411.182) divides fault among everyone involved. Even if you were partly at fault, you can recover the rest. See what to do if you were partly at fault.
Work-zone crashes
Kentucky increases fines for traffic violations in highway work zones: $500 when no one is hurt, and $500 to $10,000 when someone is injured or killed. The higher fines apply only when signs warn of the work zone and increased fines, and at least one worker is present (KRS 189.2327).
A work-zone crash can also raise questions beyond the drivers:
- Contractors may share responsibility if signs, barrels, lane markings or lane shifts weren't set up or maintained properly.
- The state. Claims against KYTC itself generally go to the Kentucky Board of Claims and must usually be filed within one year (KRS 49.120).
These claims depend heavily on facts and records, so raise them early.
What to do after a Watterson Expressway accident
- Get safe. If the car can move and no one is hurt, move to the shoulder or the next exit. If not, stay buckled with your hazards on and call 911.
- Note your location: direction, lane, nearest exit or mile marker, and whether you were in a work zone.
- Photograph the scene if it's safe, including signs, barrels, lane markings and the damage.
- Get names and contact information from other drivers and witnesses. Ask whether anyone had a dashcam.
- Get the report. Interstate crashes may be handled by Kentucky State Police or LMPD. Here's how to get your Kentucky accident report.
- Get medical care the same day if you have any pain.
- Report the crash to your insurer so PIP can start. See how Kentucky PIP insurance works.
Don't count on a traffic camera. TRIMARC, which runs the interstate cameras around Louisville, says in its FAQ that it doesn't record video from its camera feeds. Dashcams, truck cameras, vehicle data and witnesses matter more. See evidence to preserve after an accident.
Kentucky law in brief
- PIP: Unless you rejected it, Kentucky's no-fault coverage pays up to $10,000 per person for medical bills, lost wages and similar losses, whoever was at fault.
- The threshold: To claim pain and suffering from the at-fault driver, you generally need more than $1,000 in medical expenses or a qualifying injury such as a fracture or permanent injury (KRS 304.39-060).
- Deadlines: Most motor vehicle injury lawsuits must be filed within two years of the injury or the last PIP payment, whichever is later (KRS 304.39-230). See our statute of limitations guide.
