Interstate 495 Massachusetts
Interstate 495 in Massachusetts
Interstate 495 (I-495) is a major auxiliary route of Interstate 95 in the U.S. state of Massachusetts. This highway, often referred to as the "outer beltway," serves as a partial circumferential road around the Greater Boston area. The Massachusetts Department of Transportation is responsible for its maintenance.
Route Description
I-495 spans approximately 120 miles, beginning at its southern terminus in Wareham and ending at its northern terminus in Salisbury. Specifically, the highway begins as the continuation of Route 25, intersecting with Interstate 195 in West Wareham.
As I-495 progresses, it serves as a major corridor, passing through several significant towns and cities. Key intersections include:
- Route 24 near Taunton, where the highway expands to three lanes.
- Interstate 90, also known as the Massachusetts Turnpike, providing critical access to western Massachusetts and beyond.
- Interstate 93 near Andover, linking I-495 with the northern part of Boston.
I-495 also intersects with several other radial expressways such as US Route 3 and Route 2, facilitating connectivity to various road networks.
Notable Features
I-495's design as a partial beltway aids in managing the traffic flow around Boston by offering an alternate route for travelers seeking to bypass the city's core. It is instrumental in supporting the growth of suburban communities and fostering economic development by linking pivotal regions and facilitating the movement of goods and people.
The highway's route comes close to the New Hampshire state line near Haverhill, yet it remains entirely within Massachusetts. This proximity highlights its strategic importance in linking with the broader New England road network.
Economic Impact
The construction of I-495 has been pivotal in enabling the expansion of the high technology sector within Massachusetts. Cities like Marlborough and Westford have seen substantial development due to the highway's presence, attracting numerous businesses and industries to the region.
