Southbury, located in western New Haven County, sits at the crossroads of several state routes and a busy interstate. While these roads connect commuters and travelers, they are also among the most dangerous in the region. Based on crash data from the University of Connecticut (2015–2018) and recent news reports, the most dangerous roads in Southbury include I-84, Route 6, Route 67, and Main Street South.

Major Routes with High Crash Rates

• Interstate 84 (I-84)
  I-84 is Southbury’s most dangerous roadway, with over 600 crashes reported between 2015 and 2018.
  • High speeds, congestion, and bottlenecks contribute heavily to crash frequency.
  • In July 2025, a fatal crash on I-84 westbound near Exit 15 highlighted the ongoing dangers of this corridor.
• Route 6
  Route 6 ranked as Southbury’s second most dangerous roadway, with 216 crashes reported during the same four-year span.
• Route 67
  This corridor was nearly identical in crash numbers to Route 6, with 215 crashes reported.
  • A planned bridge replacement project on Route 67 is expected to improve safety and eliminate a longstanding traffic signal.
• Main Street South
  With 167 crashes reported between 2015 and 2018, Main Street South is a major local crash hotspot.
  • Intersections and crosswalks along this road have been especially problematic for both drivers and pedestrians.
• Route 188
  This route, while less traveled, still recorded 64 crashes during the same period.

Notorious Intersections

• Main Street South and the Southbury Green driveway – Frequently cited as a crash location.
• Main Street South and Flood Bridge Road – Another busy intersection with multiple collisions.
• Main Street South and Heritage Road/Old Waterbury Road – Known for its high number of crashes.
• Route 6/67 at the I-84 eastbound and westbound ramps – These interchanges are consistently congested and accident-prone.

Factors Contributing to Accidents

Southbury’s roadway dangers result from a combination of traffic patterns, infrastructure, and driver behavior. Contributing factors include:

• Congestion and high traffic volume – Heavy volumes on I-84, Route 6, and Route 67 increase crash risks during peak hours.
• Intersection safety – Complex or busy intersections, particularly on Main Street South, are frequent crash sites.
• Pedestrian hazards – Sidewalk and crosswalk issues, combined with inattentive drivers, create dangers for walkers downtown.
• Speeding – Excessive speeds contribute to many of the most serious crashes on Southbury’s major highways.
• Road design and conditions – Outdated infrastructure and poor pavement conditions also play a role in accidents.

Stay Alert, Stay Safe

Southbury’s combination of interstate traffic, state highways, and local roads makes driving here especially challenging. Whether traveling I-84, commuting along Route 6 or Route 67, or crossing Main Street South, drivers and pedestrians should exercise caution to avoid serious crashes.

Protect Yourself

Southbury’s mix of highways, state routes, and busy local roads creates elevated risks for drivers and pedestrians. Whether you’re traveling on I-84, Route 6, Route 67, or Main Street South, slowing down, staying alert, and taking extra caution at intersections and crosswalks are essential for safety.
