History


20th century


Initial construction

The Baltimore County Planning Commission first conceived the Baltimore Beltway as a county-level roadway project in 1949; by 1953, the state took over the project due to slow progress at the county level. The project was included as part of the
Interstate Highway System The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System, or the Eisenhower Interstate System, is a network of controlled-access highways that forms part of the National Hi ...
by 1956, increasing the speed of construction due to federal funds available. The first part of the Baltimore Beltway was completed in December 1955 between MD 25 (Falls Road) and the Harrisburg Expressway (present-day I-83). In 1956, the next portion of the road between the Harrisburg Expressway and MD 45 (York Road) opened. Several more segments of the Baltimore Beltway would be built in the following years, with the section from MD 168 (Nursery Road) to the Glen Burnie Bypass (present-day I-97) opening in 1957; the portions from MD 45 to MD 542 (Loch Raven Boulevard), MD 7 (Old Philadelphia Road) to US 40 (Pulaski Highway), and from MD 168 to US 40 (Baltimore National Pike) opening in 1958; the segment from MD 2 (Ritchie Highway) to the Glen Burnie Bypass completed in 1960; the portion from US 1 (Belair Road) to MD 7 finished in 1961; and the portions from MD 542 to US 1 and from US 40 to MD 25 completed in 1962. At this time, the original length of the Baltimore Beltway, from MD 2 in the south clockwise to US 40 in the northeast, was fully completed and opened to traffic, providing the first Interstate-grade bypass of Baltimore and the first beltway in the US built under the Interstate Highway System. A segment of the road completed in 1973 ran from MD 10 to MD 2, heading toward the Outer Harbor Crossing.


Windlass and Patapsco freeways

From the junction with I-95, the Baltimore Beltway was planned to extend southeast along the Back River Neck peninsula, turning south to cross the Back River near the Essex Skypark airport, then heading towards the present Outer Harbor Crossing. Part of this alignment was completed as I-695 to the south of US 40 in 1972, then as MD 702 (Southeast Freeway), extending to MD 150 by 1975. However, the section of the Baltimore Beltway between south of MD 150 to west of the Back River crossing was not built, requiring it be rerouted on portions of two freeways not originally planned to be part of it. The first was the Windlass Freeway ( MD 149), a route planned to run from I-95 at Moravia Road northeast to

with MD 702 to a point less than to the southwest where I-695 makes a sharp turn from west to south. From here, the Windlass Freeway would have continued to its southerly terminus at I-95. This sharp turn is half of what would have been another directional T interchange (which was to have become exit 37), marking the northern terminus of the Patapsco Freeway, the other freeway incorporated into the Baltimore Beltway. The Patapsco Freeway was planned to connect the Windlass Freeway to the originally-planned Baltimore Beltway. Completed in 1973, the planned Patapsco Freeway is now part of I-695. The wide median in I-695 south of exit 41 (Cove Road) is where the unbuilt beltway would have intersected the Patapsco Freeway after crossing Back River to the east, making this the southern terminus of the Patapsco Freeway. Continuing southeast, I-695 rejoins the original alignment of the beltway. Ramp stubs for the planned Windlass Freeway are present at the proposed west end at I-95 and Moravia Road, and, at the present west end at the Southeast Freeway (MD 702), the partially built junction with the proposed Windlass Freeway.

The planned junction of the Windlass and Patapsco freeways, now the point where I-695 makes a sharp turn from west to south, just to the north of where it crosses the Back River, was originally built with provisions for extending the Windlass Freeway to I-95, but this has since been reconfigured as a sharp curve on I-695.


Outer Harbor Crossing and further upgrades

The Outer Harbor Crossing is the name given to the segment of the Baltimore Beltway maintained by the MDTA. It consists of the segment of I-695 between exit 40 (MD 151) and exit 2 (MD 10), which included the Francis Scott Key Bridge. The route was originally planned as a two-lane freeway on a four-lane right-of-way, with a two-lane outer harbor tunnel across the Patapsco River. When the tunnel was advertised for construction in 1970, the bids were so high that the decision was made to construct a four-lane bridge instead. The bridge was to feature two-lane approach roads on both sides. Construction on the Outer Harbor Crossing, including the bridge, started in 1972 and was opened on March 23, 1977, completing the full Baltimore Beltway. The bridge was named the Francis Scott Key Bridge in honor of

21st century

The beltway was dedicated in honor of former Governor
Theodore McKeldin Theodore Roosevelt McKeldin (November 20, 1900August 10, 1974) was an American politician. A member of the Republican Party, McKeldin served as mayor of Baltimore twice, from 1943 to 1947 and again from 1963 to 1967, and as Governor of Marylan ...
in May 2005. During his term, McKeldin was responsible for constructing the Beltway and other state highways. Most Marylanders still refer to the highway as the "Baltimore Beltway", "695", or (mainly among Baltimore metro area residents) simply "The Beltway", like its Washington, D.C. counterpart. In March 2009, construction began on the reconstruction of the bridge that carries MD 139 (Charles Street) over I-695. The bridge is decorative, featuring ornamental street lights. As part of the MD 139 project, the interchange was reconstructed, and the traffic circle at the MD 139/I-695 ramps was removed and replaced with a traffic signal. This project cost $50 million (equivalent to $ in ) and was completed in 2012. At exit 33 (I-95/John F. Kennedy Memorial Highway), both highways had crossed over themselves so that through traffic was on the left side of the road with left-hand entrance/exit ramps connecting the crossover sections. This interchange was replaced in 2014 by a more conventional flyover ramp interchange as part of the I-95 expansion project under construction since 2007, eliminating the left-turn ramps and I-95's double crossovers. The ramp from northbound I-95 to eastbound I-695 was completed in September 2008, the ramp from westbound I-695 to northbound I-95 was completed in October 2008, the ramp from northbound I-95 to westbound I-695 was completed in November 2008 (eliminating the left-hand exit), and the ramp from eastbound I-695 to southbound I-95 was completed in May 2009. The ramps from southbound I-95 to both westbound and eastbound I-695 were completed in June 2009 and the ramp from westbound I-695 to southbound I-695 was completed in July 2009 and the ramp from eastbound I-695 to northbound I-95 opened in August 2009. In addition to rebuilding these ramps, the project also adds four ramps to service the

Francis Scott Key Bridge collapse

On March 26, 2024, the Francis Scott Key Bridge on I-695 collapsed after a ship collided with the bridge. The incident killed six construction workers and forced traffic to be rerouted to Interstate 895. Following the collapse, the section of I-695 between MD 157 (exit 43) and MD 173 (exit 1), including exit 44, was closed.


Future

There are long-term plans to add new lanes to I-695 to ease traffic congestion along the northern and western parts of the route between the two interchanges with I-95. These plans would widen the sections between I-95 and I-70 on the west side and between the

and I-95 on the north side. Work on the widening project began in 2020. In addition, there are plans to add a fourth lane between the ramps to I-795, ending the disappearing fourth lanes in this section. A multiyear project to replace the
