Boston, MA (CNN) Construction vehicles will be on the streets of Boston for the first time since 2013, the state Department of Transportation announced Friday.
The vehicles were built by the company Boldt Construction Vehicles in partnership with the Massachusetts Department of Energy, according to the state.
The state will start using them in 2021.
The new vehicles will operate on public streets and sidewalks and will provide a new form of transportation for residents of the Boston region, including downtown, the Department of Environmental Protection said in a statement.
The state announced plans in March for the vehicles to be tested in the city.
The agency said that since its debut in January, the vehicles have been used to clean up polluted streets in the suburbs and neighborhoods.
Boldt Construction also operates construction vehicles in Chicago, where the company has said it has been able to reduce traffic congestion.
The company also operates a large fleet of diesel buses in Boston.
The Boston City Council has already approved a $1 million bond for the state to purchase new vehicles and expand its fleet.
The first fleet of the Boldt construction vehicles will arrive in 2021, according the state, and the state expects to have vehicles on city streets for several years.
