State Police personnel assigned to Troop E perform public safety functions on Massachusetts Turnpike Authority roadways and properties. The fundamental tasks performed by Troop E personnel revolve around traffic management issues. However, with numerous service plazas, toll plazas, and adjacent Turnpike properties, traditional investigative law enforcement practices are necessary and common.

In 1957, the Massachusetts Turnpike (I-90) opened as a 4 lane divided highway stretching from the New York state line in West Stockbridge to Newton (123 miles). With the completion of the Callahan Tunnel in 1961 the Turnpike Authority assumed control over the combined Sumner/Callahan Tunnels. In 1965, the Turnpike was extended along a rail corridor to Kneeland Street and the old Expressway in downtown Boston. In 1970, due to increased traffic demands, the Turnpike widened I-90 a 6 lane divided highway from Interchange #9 in Sturbridge to Interchange #15 in Newton. During this widening project Interchange #11A was added. In 1998, Interchange #10A was added. This brought the Turnpike to a total of over 1,100 lane miles.

The character and scope of the Troop E mission has evolved over the years. The most rapid and challenging changes began with the opening of the Ted Williams Tunnel (TWT) in 1995. In 1997, the Turnpike Authority assumed control over the newly developed Metropolitan Highway System (MHS). The MHS encompasses I-90 from Interchange #15 in Newton to Route 1A in East Boston including a stretch of I-93 from Dorchester to Somerville. With the advent of the MHS, the jurisdiction of Troop E has increased by greater than 100 lane miles through the most congested city in New England. These additional miles include nearly 42 miles of subterranean or tunnel lane miles. These tunnels; TWT, O'Neil, Liberty, Callahan/Sumner, Cana, and adjacent ramps, present unique challenges to public safety.

Troop E is headquartered in South Boston, adjacent to the TWT. There are four sub-stations located in Weston (E-1), Charlton (E-2), Westfield (E-3), and South Boston (E-4). Troop E also has a specialized Commercial Vehicle Enforcement Unit as well as a Motorcycle Team. By constantly upgrading equipment and techniques, Troop E has and will remain a major factor in making I-90 statistically one of the safest highways in the country.
