Illinois Route 15 and Route 159 are two of Belleville’s most car accident-prone roads because of high traffic volumes, poorly configured intersections, frequent construction zones, and driver behaviors like speeding and distracted driving. Route 15 regularly experiences heavy congestion and roadwork that raise the likelihood of crashes, while Route 159 carries significant north-south traffic through dense commercial areas where collisions are a recurring problem.

What Makes Route 15 So Dangerous in Belleville?

Route 15 is a 149-mile east-west highway cutting directly through Belleville’s busiest corridors. Its crash history stems from high traffic volume and difficult intersection configurations, which prompted the Illinois Department of Transportation (IDOT) to replace signalized intersections at the IL 15 and IL 158 interchange with roundabouts to improve traffic flow. Although those changes helped, crashes on this stretch are an ongoing concern.

What Are the Most Dangerous Intersections Along Route 15?

These two intersections are especially hazardous:

  • The segment near Frank Scott Parkway backs up quickly during peak hours, raising the risk of rear-end and side-impact collisions as drivers react late to slowing traffic.
  • The intersection of IL 13 and IL 15 at Green Mount Road is among the busiest and most crash-prone in the Belleville area, where multiple routes converge, and driver confusion is common.

Why Is Route 159 a High-Risk Road?

Route 159 runs north-south through a dense mix of commercial properties, residential neighborhoods, and busy intersections. The road poses ongoing safety challenges because of high traffic density and frequent roadway changes, including work tied to railroad crossings. The intersection of IL 159 and South Belt East ranks among the busiest in the city, where turning movements and high approach speeds create conditions that lead to serious crashes.

What Types of Crashes Happen Most Often on These Roads?

Both routes see a range of collision types, though some patterns stand out. Common crash types on Route 15 and Route 159 include:

  • Rear-end collisions near congested intersections and construction zones
  • Side-impact crashes at multi-lane intersections where drivers misjudge gaps in traffic
  • Median-crossing crashes on Route 15, where vehicles traveling at highway speeds enter oncoming lanes
  • Pedestrian incidents near commercial areas along Route 159

What Driver Behaviors Contribute to Crashes on These Routes?

Unsurprisingly, distracted driving and excessive speed are the most common contributing factors on roads with the highest crash rates in the Belleville area. Both behaviors are particularly dangerous where traffic conditions change quickly, such as near shopping centers, school zones, and active construction areas.

Who Can Be Held Liable After a Crash on Route 15 or Route 159?

The at-fault driver is most often held responsible, but other parties may also share accountability. For example, a property owner whose poorly maintained entrance creates a hazard or a contractor overseeing an unsafe construction zone could face liability – depending on what caused the collision.

How Long Does an Injured Driver Have to File a Lawsuit in Illinois?

Illinois law gives most personal injury claimants two years from the date of the crash to file a lawsuit. Missing that window can permanently eliminate the right to pursue compensation, regardless of how strong the case may be. Acting promptly also preserves physical evidence, witness recollections, and traffic camera footage that may otherwise become unavailable.
