A speed bump may soon be coming to your neighborhood, as the city has been working on improving road safety for years.

The city of Boston will install more than 2,000 of the bumps as part of its “Safety Surge,” which began in October. The city plans to have more than 400 bumps installed by the end of July.

The humps themselves are about three inches high and about 12 to 14 feet long, according to the city. Cars can drive smoothly over them at speeds of 20 miles per hour or slower.

The city is focusing on smaller neighborhood streets for the speed bumps, which will be built in 150- to 350-foot increments. They will not be built on busier streets or streets with an MBTA bus route.

“The plan calls for adding 500 speed bumps per year with the goal of installing them on all nearly 400 miles of eligible city streets,” a spokesperson for the Streets Cabinet told Boston.com. “This will take time to implement, but the city is committed to creating safer streets in all of our neighborhoods.”

A spokesperson confirmed that 500 speed bumps will be added annually through 2026. According to a city map, speed bump projects have already been completed on streets in Mattapan, Dorchester and Roxbury.

Boston Public Works reported on social media that workers were painting a bump with stripes on Peter Parley Road in Jamaica Plain last month.

More speed bumps are planned for Mission Hill and Allston-Brighton. According to the city’s website, there is no opportunity for resident feedback, but residents will be notified before a speed bump is built on their street.

Earlier, a spokesperson said the city had already installed 600 speed bumps before the start of the “Safety Surge” program, which also includes redesigning intersections and improving pedestrian traffic signals.

Last year, 20 percent of all fatal crashes in Massachusetts were pedestrians, according to nonprofit WalkMassachusetts’ 2023 report. Boston’s 16 fatal crashes last year included eight pedestrian fatalities. Speed ​​was the biggest factor behind the crashes, according to the group’s co-executive director.
