Interstate 95 (I-95): Route, Length, States and Safety Data

How long is I-95?

The Federal Highway Administration's Route Log credits I-95 with 1,904.61 miles as of January 2026. No other north-south Interstate is longer, and only five routes of either direction carry more Route Log miles.

Search for the length and you will see 1,919, 1,920 or 1,926 miles. Interstate Guide prints 1,919.31, a total its own state table does not reproduce, and the 1,926 figure belongs to a road-trip planner that measures a full trip rather than the route itself. The state rows below are the current federal numbers, and they add up to the total.

Florida has the most I-95 mileage at 381.93 miles, with Maine second at 303.11. The shortest piece is in the District of Columbia, where the road crosses the Potomac on the Woodrow Wilson Bridge for 0.13 of a mile.

Where I-95 starts and ends

The southern end is US 1 in Miami. The northern end is the Houlton-Woodstock border crossing in Houlton, Maine, where the highway continues into New Brunswick as Route 95.

Between them the route runs through Jacksonville, Savannah, Richmond, Baltimore, Philadelphia, New York, New Haven and Providence. It skirts Washington on the eastern half of the Capital Beltway and Boston on Route 128, sharing about 37 miles of pavement with that older ring road.

Interstate junctions along I-95

The main Interstates I-95 crosses are listed here from south to north. I-93 meets it twice in Massachusetts, once on each side of Boston. Its 303 miles in Maine cross no other main Interstate.

Fatal crashes on I-95

Fatal crashes on the I-95 mainline killed 1,668 people from 2020 to 2024, about 334 a year. Spread over the route, that is 17.5 deaths per 100 route miles each year, against 9.5 for the Interstate system as a whole. Only four Interstates over 100 miles have a higher rate.

Florida accounts for 588 of the deaths, and the five counties with the highest counts are all on its Atlantic coast, led by Palm Beach and Broward. Pennsylvania's 42 miles through Philadelphia match Florida's rate at about 31 deaths per 100 miles a year. Maine, with long rural stretches north of Bangor, has the lowest rate on the route at 3.4. Yearly deaths peaked at 349 in 2022 and fell to 302 in 2024.

Bridges on I-95

The 2025 National Bridge Inventory lists 2,044 bridges that carry the I-95 main line, and half of them were built in 1967 or earlier. Forty-five rate Poor, about 2 percent. Massachusetts has the most at 10, then Pennsylvania with 8 and Connecticut with 6.

On June 11, 2023, a tanker truck fire under I-95 in Philadelphia brought down a section of the northbound lanes. A temporary roadway reopened the route twelve days later.

Tolls on I-95

FHWA's toll inventory lists 16 facilities on I-95 as of January 2023. A northbound trip from Baltimore to New York pays at the Fort McHenry Tunnel, on the Maryland and Delaware stretches of the JFK Memorial Highway, on the New Jersey Turnpike and at the George Washington Bridge. Farther north the New England Thruway, a short New Hampshire turnpike and the Maine Turnpike charge again.

The express lanes in South Florida and Northern Virginia are optional and priced by demand, so the rate changes through the day. Virginia's lanes have grown since the inventory: a 10-mile Fredericksburg Extension opened in August 2023. FHWA files the Pennsylvania entry under the turnpike's Northeastern Extension; since 2018, I-95 has used the turnpike's Delaware River Bridge, tolled westbound. The mileage column is the length FHWA gives for each facility.

I-95 auxiliary routes

Eight three-digit routes branch from I-95, and the same numbers repeat from state to state. I-295 shows up in 11 states and the District of Columbia as several separate roads, from the Jacksonville beltway to the route through Portland, Maine. Georgia, South Carolina and New Hampshire have none.

How I-95 was finished

I-95 was designated in 1957, but it did not run as one unbroken Interstate until September 2018. That month a new interchange with the Pennsylvania Turnpike near Philadelphia closed the last gap.

Some of I-95 was built as toll roads before the 1956 highway act created the Interstate system. The Maine Turnpike opened in 1947 and the New Jersey Turnpike in 1951, and both still charge tolls. The Richmond-Petersburg Turnpike, authorized in 1955 and opened in 1958, stopped collecting them in 1992. In Northern Virginia, the Springfield Interchange rebuild finished in 2007, and across the Potomac the 10-lane Woodrow Wilson Bridge replacement was completed in 2008.
