The south end of Interstate 295 was originally located at a cloverleaf interchange with the Capital Beltway. It included a roadway stub for an unconstructed extension of the freeway southward toward Indian Head. Eventually 1.7 mile long ramps were constructed between I-295 and MD 210 (Indian Head Highway) at Oxon Hill. Opened in 1990, these ramps are not inventoried in the Maryland Department of Transportation (MDOT) Highway Location Reference (HLR) log as either I-295 or MD 210.
Indian Head, which is located in Charles County to the south, is connected to the Capital Beltway and I-295 along MD 210. Construction from Fall 2016 to Fall 2020 converts a 1.8 mile section of Indian Head Highway into a limited access highway.
The cloverleaf interchange joining I-295 with I-95/495 (Capital Beltway) was upgraded to a multi level systems exchange during the Wilson Bridge Reconstruction Project in the mid-2000s. Maryland DOT/SHA modified signs during that work on Interstate 295 southbound to read “MD 210 South – Indian Head” in place of “I-295 South – Indian Head.” Additional work completed in 2009 added ramps with newly constructed National Harbor Boulevard to the south.
Baltimore-Washington Parkway extends north from MD 201 (Kenilworth Avenue Freeway) through Prince George’s County to Fort George G. Meade, Jessup, Thurgood Marshall Baltimore-Washington International Airport (BWI) and Cherry Hill in the city of Baltimore. Maintenance of the limited access highway is split between the National Park Service (NPS) and MDOT.
The entire Baltimore-Washington Parkway was posted as Interstate 295 from January to July 1969. However, the cost of upgrading the parkway to modern design standards was prohibitive and not funded by Interstate funds. In the same year, the parkway Interstate mileage was reallocated to several proposed highways within the Washington Beltway. Many of these proposed freeways within the beltway were never constructed. With the completion of parallel eight-lane Interstate 95 in 1971, plans for further upgrading the parkway to modern standards were shelved.3
The parkway pre-dates most of the Interstate system; it was constructed between 1947 and 1954. The first section completed was at the north end. Signed as MD 295, the state-maintained section north from MD 175 into Baltimore opened in 1952. The NPS section from MD 175 south to U.S. 50 opened on October 22, 1954.3
