Interstate 95 in Maryland is a major highway that runs diagonally from northeast to southwest, from Maryland's border with Delaware, to the Woodrow Wilson Bridge, briefly entering the District of Columbia before reaching Virginia. The route is one of the most heavily traveled Interstate Highways in Maryland, especially between Baltimore and Washington, D.C., despite alternate routes along the corridor, such as the Baltimore-Washington Parkway, U.S. 1, and U.S. Route 29. Portions of the highway are tolled.

Between the Delaware state line and the Baltimore City line, I-95 is known as the John F. Kennedy Memorial Highway.


Counties traversed

From south to north, I-95 traverses the following counties in Maryland:

Route description


Capital Beltway

Interstate 95 enters the state of Maryland concurrent with Interstate 495, the Capital Beltway. The roadways, four lanes in either direction, travel together over the Woodrow Wilson Memorial Bridge and touch down in Prince George's County west of Forest Heights. I-95/I-495 immediately encounter the southern terminus of Interstate 295, known as the Anacostia Freeway, a route that serves downtown Washington D.C. and connects to the originally planned alignment of I-95 through D.C., Interstate 395. Just beyond I-295 the two routes interchange with MD 210, a major north–south route into southern D.C.

The two Interstates continue along the Capital Beltway, interchanging with various local highways such as MD 5 (Branch Avenue) and MD 4 (Pennsylvania Avenue) on either side of Andrews Air Force Base, which the Beltway travels very close to near its northern edge. Turning north past the MD 4 interchange, the Beltway runs through Glenarden, interchanging with MD 202, US 50/secret Interstate 595, and MD 450, the latter route offering access to the New Carrollton metro station and the New Carrollton metropolitan area.

Turning northwest the Beltway enters Greenbelt Park, intersecting the Baltimore-Washington Parkway in the northeastern edge of the park. Just after the B-W Parkway the two routes interchange with MD 201, which connects to the southern terminus of the B-W Parkway at US 50 (New York Avenue) near the D.C. line. Now turned fully west, the Beltway runs through the northern edge of College Park, interchanging with the College Park metro station's access roadway and US 1.

Beyond the US 1 interchange, I-95 encounters its own route at the College Park Interchange, and separates from I-495 within this interchange. I-495 continues west, alone, on the Capital Beltway to Interstate 270, while I-95 turns north onto its own planned alignment. The interchange includes access to a Park and Ride.

Between the Beltways

Traffic is congested on I-95 southbound in Baltimore.

Running northeast, I-95, still eight lanes wide, passes through Beltsville, interchanging with MD 212 near the community. The highway, completed in 1971, runs through undeveloped land and a long highway construction zone (as of 2008) where the new Intercounty Connector toll road (MD 200) will connect (as of 2011 or 2012) before interchanging with MD 198 just west of Laurel. Passing over the Patuxent River just south of the Rocky Gorge Dam, the route enters Howard County and promptly interchanges with MD 216. North of the MD 216 interchange, the route encounters its first rest area in the state of Maryland, with each carriageway served by its own facility. Continuing northeast, I-95 intersects MD 32 at a modified directional cloverleaf. Within this interchange, I-95 grade-separates, with the northbound carriageway passing over MD 32 and the southbound carriageway passing under MD 32, allowing left exits from both of the latter's carriageways to merge into the left lanes of I-95 without conflict.

North of this unusual interchange, I-95 encounters MD 175, the main access route into Columbia, at a less-radical directional cloverleaf interchange. After the MD 175 interchange comes the MD 100 interchange, providing access to Ellicott City, US 29, and Interstate 70 to the west, and the Baltimore-Washington Parkway and Interstate 97 to the east. Just beyond this interchange, I-95 encounters three more of its auxiliary routes within Maryland: Interstate 895, which splits at a directional wye within the Patapsco Valley State Park, just south of the Patapsco River; Interstate 195, a short spur to Baltimore-Washington International Airport, and Interstate 695, the Baltimore Beltway, a full-circle beltway around Baltimore that offers a full freeway bypass of the city and that connects to Interstate 70, Interstate 83, and Interstate 97. Traffic not authorized to make use of either of the direct (tunnel) routes through Baltimore is encouraged to use the eastern half of I-695, which crosses the Patapsco River via the Francis Scott Key Bridge.

Within Baltimore

After interchanging with I-695, I-95 enters the city of Baltimore. The route, completed in 1985 with the opening of the Fort McHenry Tunnel, provides direct access to downtown Baltimore via Interstate 395. West of the southern terminus of I-395, the route intersects the northern end of the Baltimore-Washington Parkway, the first freeway route to connect Washington D.C. with Baltimore. Skirting the southern edge of Fort McHenry, the route crosses the Patapsco River via the Fort McHenry Tunnel, then turns north to serve East Baltimore, crossing over and paralleling Interstate 895. The two routes eventually merge with one another just after I-95 crosses the city line to the south of Rosedale.

John F. Kennedy Memorial Highway

I-95, once again eight lanes wide, now travels out of Baltimore on the John F. Kennedy Memorial Highway. The route is eight lanes wide from the northern terminus of the Baltimore Harbor Tunnel Thruway (Interstate 895) as far as MD 24, and six lanes wide from there to the Delaware border. The highway interchanges with Interstate 695, the Baltimore Beltway, at a unique double-crossover interchange.

The route serves various towns to the northeast of Baltimore:

I-95 crosses the Susquehanna River on the Millard E. Tydings Memorial Bridge, named for a long-time political figure in Maryland who died in 1961. The bridge collects tolls for northbound traffic only.

Interstate 95 finally exits Maryland near the town of Elkton, entering Delaware.

Service areas

Just as in Delaware, the northern segment of I-95 in Maryland has service areas in the median that serve both directions of traffic. This dates back to its days as a two-state toll highway. Between the Delaware line and the Baltimore City line, two service areas are available - Maryland House, opened in 1963, at milepost and (between exits 80 & 85) in Harford County, and Chesapeake House, opened in 1975, at milepost 97 (between exits 93 & 100) in Cecil County. As of 2009, the MdTA is engaged in a process to identify a contractor to re-develop the two service areas, which are considered out-dated and worn.[2] There is also a rest area between Baltimore and Washington, D.C., located in Howard County. Unlike the above two rest areas, which are located in the median, this rest area is located on the shoulders, with separate facilities for each carriageway.

Auxiliary routes

Interstate 95 in Maryland has a nearly full quiver of auxiliary routes:

An older version of the I-95 shield as used in Maryland.

Northeast Freeway

Under the original plans for Interstate 95 in Maryland, the route would not have followed the eastern half of the Capital Beltway from the Woodrow Wilson Bridge to the College Park Interchange. Instead, it would have exited the District at New Hampshire Avenue (MD 650), following the Northeast Freeway, and after passing through Northwest Branch Park, junctioned I-495 at the College Park Interchange, integrating seamlessly with the existing segment of I-95 at that interchange. This route was canceled in 1977, and I-95 rerouted, after the District government canceled the North Central Freeway, which would have linked to the Northeast Freeway at its southern end and carried I-95 deeper into the District.

Unbuilt interchanges

I-95 has at least four unbuilt interchanges along its route, with three located within the city of Baltimore. Traveling northbound, the first interchange encountered is the College Park Interchange, the site of the northern crossing of I-95 and I-495 and the northern end of the Northeast Freeway. This interchange, while technically incomplete, was modified in late 1986 to bring it fully into service; today, all parts of the interchange are in regular use.

The other three interchanges are located in the city of Baltimore: the planned eastern terminus of Interstate 70; the planned southern terminus of Interstate 83; and the planned southern terminus of the Windlass Freeway. All three unbuilt interchanges incorporate interchanges with local roads.

Changes in jurisdiction

Originally, there were five changes in jurisdiction over maintenance of Maryland's segment of I-95. Between the Virginia state line and the Baltimore city line, the route is maintained by the Maryland State Highway Administration. Within Baltimore, jurisdiction went from the city to the Maryland Transportation Authority (MdTA) and back to the city. Between the city line and Exit 67 (MD 43) the route was again maintained by the Maryland State Highway Administration. North of Exit 67 to the Delaware state line, the route is maintained by the MdTA.

Now, between the southern Baltimore city line (near Exit 49, the southern I-695 interchange) and the Delaware state line, the route is maintained entirely by the MdTA.[3] The Maryland State Police and the Maryland Transportation Authority Police share police duties with the MSP patrolling from the Northern Baltimore City/Baltimore County Line to the Delaware state line and the MdTA Police patrolling from exit 49 to exit 64(Beltway to Beltway), and toll revenue from the two transportation facilities on this segment finance the maintenance and expansion of the route.

Major events

  • On January 13, 2004, a tanker truck carrying flammable liquid fell off of the southbound ramp from the Harbor Tunnel Thruway to I-95, landing on the travel lanes and causing a massive explosion, crushing several vehicles and killing four.[4] Despite this, no damage was done to either highway and both were reopened early in the morning on January 14, 2004.[5]
  • On October 16, 2004, a sudden hail storm just north of Baltimore caused a string of 33 accidents, involving at least 130 vehicles, in an 11-mile (18 km) stretch of I-95. Both northbound and southbound lanes were closed down. The northbound lanes were reopened seven hours later, and the southbound lanes required a further 12 hours to clean.[6]
  • On January 16, 2007, an exhausted truck driver lost control of his tanker truck, causing it to overturn on the northbound carriageway near Maryland House in Harford County. The route was closed for a time when leaks were discovered in the tank, which was carrying a corrosive alkaline material; the outermost right lane remained closed until 15:00 that day.[7]
  • On October 4, 2008, at around 2:00 am, a tanker carrying acetone overturned on the southbound lanes south of exit 85, closing down both the northbound and southbound lanes for over eight hours.[8] According to State Police, the tanker leaked acetone and other flammable liquids after overturning. Four others were also involved in the crash and were taken to the University of Maryland Shock Trauma Center in Baltimore.[8] Both the northbound and southbound lanes reopened at around 11:00 am on the same day.[8]
