D.C.


Suitland Parkway links southeast Washington, D.C. with Andrews Air Force Base at Maryland 4 (Pennsylvania Avenue) near Forestville. The highway carries four lanes overall along a 9.35-mile controlled-access route. Several interchanges and a handful of at-grade intersections lie along the route. Like the George Washington Memorial and Clara Barton Parkways, the Maryland section is maintained by the National Park Service.

Suitland Parkway begins at a signalized intersection with Maryland 4 (Pennsylvania Avenue) near its interchange with Interstate 95. Departing westward, the parkway first interchanges with Patrick Avenue at the north gate to Andrews Air Force Base. From there the route continues west underneath Interstates 95 & 495 (there is no direct access between the parkway and Capital Beltway).

Originally constructed during World War II by the Bureau of Public Roads (now the FHWA), Suitland Parkway was built to link the military facilities of Bolling Field Air Force base with Camp Springs (Andrews A.F.B.). Opened December 9, 1944 the parkway later became part of the National Capital Parks system, which preserves the forest and rural scenery along the route. This designation led to Suitland Parkway inclusion in the National Register of Historic Places on June 2, 1995.

Suitland Parkway continues west and north to a three-quarter cloverleaf interchange with Maryland 458 (Silver Hill Road). National Park Service maintained sections of the road include brown signs with Clarendon font in most places. However replacement signs feature Arial font and some signs, such as those for the Maryland 5 interchange, are simply missing. Just before the Silver Hill Road interchange is an at-grade intersection for Meadowview Drive and the Meadowview subdivision. Meadowview is only accessible via the NPS-maintained Suitland Parkway.

Suitland Parkway gains an urban feel upon crossing the District of Columbia line at the Southern Avenue overpass. Sign standards decrease within Washington, with substandard guide signs for the ramps to Alabama Avenue, Sheridan Road and Martin Luther King Jr. Avenue. Pictured here is the approach to the Sheridan Road slip ramp for MLK Jr. Avenue.

The roadway is used by commuters and visitors alike. Connections with South Capitol Street to the north provide a direct route into downtown Washington and the United States government center. Additionally drivers bound for the new Washington Nationals baseball park can use Suitland Parkway from the south, as the new stadium lies along South Capital Street north of the Frederick Douglass Memorial Bridge.

A modified cloverleaf interchange joins Suitland Parkway, South Capitol Street / Douglass Memorial Bridge, and Interstate 295 (Anacostia Freeway). Suitland Parkway merges with South Capitol Street ahead of the Douglass Memorial Bridge.


South Capitol Street travels north from the Interstate 295 interchange with Suitland Parkway at Anacostia Park. The route utilizes the Frederick Douglass Memorial Bridge across the Anacostia into south central Washington. Following a four-lane boulevard, South Capital Street first passes by the new Washington Nationals stadium site before diving below M Street. Four blocks north of the M Street overpass are ramps to the Southeast Freeway (Unsigned Interstate 695) directing motorists to Interstate 395 north and south.  

South Capitol Street touches down at a signalized intersection with Potomac Avenue at the north end of the Douglass Bridge. Construction is well underway at the Washington Nationals ball park, with opening day slated for March 30, 2008. The stadium will seat 41,000.

Looking northward along South Capitol Street at P and O Streets, adjacent to the new Nationals baseball stadium. Two years ago this scene existed underneath the South Capitol Street viaduct.

$27 million construction involving the Frederick Douglass Memorial Bridge continues with an expected completion of April 2008. Work already completed includes the removal of a 400′ viaduct section (between Potomac Avenue and O Street) at the north end of the bridge and lowering of the north approach of the bridge to blend the span into the surrounding area. This work is part of an urban renewal project centered around the new Nationals ball park. An intersection with Potomac Avenue on the north side of the bridge begins the new urban boulevard leading north. Before this was completed, an industrial style viaduct carried motorists northward into a blighted area. The bridge carries an average of 77,000 vehicles per day.

A study is still underway on the overall replacement of the 1950-built Frederick Douglass Memorial Bridge with a new signature span. Design concepts include some elaborate draw and swing spans on cable-stayed and arch bridges. Details of the study are available at South Capitol Street Bridge Study and JD’s “Near Southeast” DC Redevelopment blog.

South Capitol Street sinks below M Street on the approach to Interstate 695 and the United States Capitol complex. Ramps ahead join Interstate 695 west at its interchange with Interstate 395.

Today’s thoughts involve reflections on the Interstate 95 corridor between Florida and the northeast U.S. The reviled freeway in some cases, Interstate 95 suffers from overrunning by travelers headed to/from Florida, a number that increases significantly every year. Respective DOT’s are trying to keep up with growth with various expansion and interchange projects throughout the 800-mile drive from Daytona Beach northward to Washington, D.C. Profiled below are some of the construction projects we’ve encountered over the last few weeks. 

Interstate 95 is rather docile in Volusia County south of Interstate 4, but north of it is a different story. The influx of traffic from Orlando and its array of resort areas puts a crush of traffic on the freeway between Daytona Beach and Jacksonville. Surprisingly not all of this corridor is yet to six-lane capacity. St. Johns and Volusia Counties are already six-lanes, but Flagler County is not. Therefore crews are out working on the expansion of Interstate 95 to eliminate the bottleneck between Interstate 4 and Interstate 295. From the FDOT website, expansion of the 18.6-mile stretch in Flagler County began on March 14, 2005. Completion date is unclear.

In a related project pertaining to the Interstate 95 corridor, upgrading of the Florida 9A (Future Interstate 295) diamond interchange with Florida 202 (J. Turner Butler Boulevard – JTB) is also underway. Florida 9A provides an eastern bypass of downtown Jacksonville as well as a commuter route for southeast Jacksonville. The substandard interchange between the two freeways is the only thing preventing the eastern beltway from becoming part of the Interstate 295 corridor. Upon completion of the $80.5-million project, high-speed flyovers will shuttle motorists between Interstate 295 and the JTB. Work began in July 2005 with a 2009 completion date anticipated.
