Deaths = people killed in crashes on the road, 2020–2024. A crash counts for the first signed Interstate, US or State route of its location; county and unsigned roads are not ranked because their numbers repeat. The stretch is the ~7-mile square with the most deaths on that road. Source: NHTSA FARS.

Questions
Deadliest roads — FAQ
What is the deadliest highway in Massachusetts?
I-495 is the deadliest road in Massachusetts: 79 people died in crashes on it from 2020 to 2024, the worst stretch being near Middlesex County (8 deaths within about 7 miles). Next: I-93 (50) and I-95 (47). Long, busy highways lead on totals; the deadliest-stretch column shows where on each road the deaths cluster.
Why is there no deaths-per-mile figure?
FARS records where each fatal crash happened but not how long each route is or how much traffic it carries, so we show totals and the worst ~7-mile stretch rather than a rate we would have to estimate.
Where does this data come from?
NHTSA's Fatality Analysis Reporting System, which records every fatal crash on US public roads, for 2020–2024. Each crash is credited to the first signed Interstate, US or State route of its trafficway.
