Interstate 95: The East Coast's Primary Arterial Highway
Interstate 95 (I-95) is one of the oldest and most critical routes within the Interstate Highway System, serving as the primary north-south backbone of the United States' East Coast. Stretching from the tropical shores of Miami, Florida, to the Canadian border in Houlton, Maine, I-95 facilitates the movement of millions of travelers and vast quantities of freight across the most densely populated corridor in the country.
For decades, the route was famous for a significant gap in Central New Jersey caused by the cancellation of the Somerset Freeway. However, this was resolved on September 22, 2018, when a new interchange between the Pennsylvania Turnpike and I-95 opened. This completion allowed the highway to be rerouted via the Pearl Harbor Memorial Turnpike Extension, creating a continuous, uninterrupted Interstate route from Maine to Florida for the first time in history.

Route Overview and Regional Analysis
The Southern Segment: Florida to North Carolina
In the South, I-95 begins in Miami and travels north through Florida and Georgia. Upon entering South Carolina, the highway shifts from a coastal alignment to a more inland route. In this state, it avoids major urban centers, with Florence being the largest city along its path. Key intersections here include I-26, providing access to Charleston and Columbia, and I-20, which connects to Atlanta.
As it enters North Carolina, I-95 acts as a geographic divider between the central Piedmont and the eastern Atlantic Plain. The route remains largely rural, bypassing major hubs like Raleigh and Durham, while serving medium-sized cities such as Fayetteville, Wilson, and Rocky Mount.
The Mid-Atlantic Region: Virginia to New Jersey
The Mid-Atlantic section of I-95 traverses the most populous urban regions in the United States. In Virginia, the route passes through Petersburg and Richmond, eventually turning northeast toward Northern Virginia. In the Washington metropolitan area, it runs concurrently with the Capital Beltway (I-495) and crosses into Maryland via the Woodrow Wilson Bridge.
In Delaware, I-95 is the state's only two-digit interstate, crossing the state via the Delaware Turnpike. Upon entering Pennsylvania and New Jersey, the route utilizes several major toll roads. In New Jersey, I-95 follows the New Jersey Turnpike, crossing the Delaware River and eventually the Hudson River via the George Washington Bridge to enter New York City.
The Northeast and New England: New York to Maine
Within New York City, I-95 is composed of several named expressways, including the Trans-Manhattan, Cross Bronx, and Bruckner expressways. It then follows the New England Thruway into Connecticut, where it closely hugs the southern coast, passing through Stamford, Bridgeport, and New Haven.
The final leg of the journey takes the highway through Rhode Island and Massachusetts—where it intersects with the Massachusetts Turnpike (I-90)—before passing through New Hampshire and terminating at the Canadian border in Maine.

Infrastructure and History
I-95's development often involved incorporating existing toll roads into the Interstate system. While some early toll sections, such as the Connecticut Turnpike and the Richmond–Petersburg Turnpike, eventually became free, many others remain tolled today. Current toll sections include the New Jersey Turnpike, the Pennsylvania Turnpike, and the Maine Turnpike, among others.
Looking forward, a multistate agreement is currently studying the 1,054-mile corridor from Petersburg, Virginia, to Florida. The goal of this initiative is to implement widening and reconstruction projects to reduce chronic congestion and improve safety.

Which major cities does I-95 pass through?
The highway passes through or near several major metropolitan areas, including Miami, Richmond, Washington D.C. (via auxiliary routes), Philadelphia, New York City, Boston (via auxiliary routes), and Portland.
Are there still tolls on I-95?
Yes, tolls remain on several sections, including the New Jersey, Pennsylvania, New Hampshire, and Maine Turnpikes, as well as the George Washington Bridge and the New England Thruway.
What is the purpose of the current multistate agreement for I-95?
The agreement focuses on studying the corridor from Petersburg, Virginia, to Florida to identify opportunities for widening and reconstruction to reduce traffic congestion and enhance safety.
What happened to the Somerset Freeway?
The Somerset Freeway was a planned alignment of I-95 in New Jersey that was canceled in 1983, creating a gap in the interstate's routing that lasted until the 2018 rerouting via the Pennsylvania Turnpike.
