The 10 Deadliest Highways in Massachusetts

Nearly 43,000 people died in motor vehicle crashes in the United States in 2021, according to estimates by the National Highway Traffic Safety Administration (NHTSA). That figure marks a 10.5% increase in deaths from 2020 and the highest number of traffic fatalities in 16 years.

Fatal motor vehicle crashes in Massachusetts were responsible for 417 of those deaths. Of the total accident fatalities in the state, around 59% were the occupants of vehicles, 18% were pedestrians, 17% were motorcyclists, and 1% were bicyclists.

While Massachusetts still has one of the lowest rates of fatal crashes per capita in the U.S., some roads in the state are more dangerous than others. In order to identify which highways are the deadliest, Stacker ranked 2020 traffic fatality data compiled by NHTSA. Ties between locations were broken by the total quantity of crashes when possible.
