SOMERVILLE, MA – Last week, Somerville implemented a blanket speed limit of 25 mph on the majority of its roadways.

Signs will be posted indicating when speed limits are higher; according to the city, these streets include main thoroughfares and state roads like Rt. 16 and McGrath Highway. There will also be indicators for lower speed limits, such as slow zones near schools.

The change in speed limits coincided with the implementation of the Municipal Modernization Act, a law permitting cities and towns to decrease their speed limits to 25 mph in highly congested areas and designate 20 mph safety zones.
