New Canaan, located in lower Fairfield County Connecticut, combines suburban neighborhoods, a vibrant downtown, and major commuting routes. Despite its size, several roads in New Canaan have been identified as high-risk corridors for drivers, pedestrians, and cyclists. Based on police reports, local news, and crash data, the most dangerous roadways in New Canaan include the Merritt Parkway (Route 15), Ponus Ridge Road, Route 106, and several busy downtown intersections.
Major Routes with High Crash Rates
- Merritt Parkway (Route 15)
The Merritt Parkway consistently sees a high number of crashes due to its narrow lanes, lack of shoulders, and limited visibility.- In November 2024, an 85-year-old man was killed in a multi-car crash near Exit 36 in New Canaan.
- In August 2025, a truck struck an overpass near Exit 36, forcing a shutdown of the southbound side and highlighting ongoing clearance and congestion issues.
- Ponus Ridge Road
This winding, narrow road has been identified as particularly hazardous, with multiple fatal accidents. Excessive speed and limited visibility contribute heavily to its dangers. - Route 106 (Old Stamford Road)
This state road is a frequent site of crashes, particularly between Weed Street and Lapham Road. Several trucks have become stuck under the railroad overpass here, creating dangerous situations. Rear-end crashes with injuries have also been reported on this stretch. - Route 124 (South Avenue and Main Street)
The intersection of Route 124 with Route 15 ramps is known as a dangerous location. In September 2024, a serious crash involving two vehicles and a juvenile required assistance from the Darien Police Accident Investigation Team.
Notorious Intersections
- Elm Street and Park Street – Identified in a 2018 police analysis as the highest-incidence crash location in downtown New Canaan, largely due to angled parking and vehicles backing into traffic.
- Cherry Street and South Avenue – Another high-incidence downtown intersection.
- Cherry Street and Main Street – Located just one block away, this intersection also ranks among the most hazardous in town.
Factors Contributing to Accidents
- Parking lots – A significant percentage of crashes occur in parking lots, including at the high school, YMCA, and downtown shopping areas.
- Impaired driving – In August 2025, a two-car crash at New Norwalk Road and Locust Avenue was linked to a driver under the influence.
- Following too closely – Tailgating is a leading cause of collisions in town.
- Road conditions and speed – On roads like Ponus Ridge, winding curves, poor lighting, and speeding contribute to frequent and severe crashes.
- Congestion and distracted driving – Downtown intersections are prone to fender benders and pedestrian incidents due to heavy traffic and inattentive drivers.
Stay Alert, Stay Safe
Whether driving on the Merritt Parkway, navigating Ponus Ridge, or parking downtown, New Canaan’s roadways demand extra caution. Drivers should slow down, remain alert, and pay close attention at busy intersections and in pedestrian-heavy areas.
