The elevated ramp under construction in the foreground is the B-610 bridge that will be the 2-lane express flyover ramp (the I-95 southbound through route) from the Beltway Inner Loop (from Wilson Bridge) to I-95 south. The B-610 bridge is 4,870 feet long.

In the center of the photo is the B-613 bridge that is part of the relocated Beltway Outer Loop roadway. The B-613 bridge is 1,395 feet long. The relocated Beltway Outer Loop roadway opened to traffic a week before this photo was taken.

Phases 4 and 5 of the SIIP included extensive construction of sound barrier walls along the western, southern and eastern edges of the interchange and approaches.

Notice in the lower right of the photo, the new realigned 2-lane ramp from I-395 southbound to I-495 westbound, and the original ramp (now closed) to the left of the new ramp. The ramp was relocated to provide space for the larger interchange complex.

The Beltway Outer Loop roadway was relocated in the interchange area, inboard of its original location west of the interchange, to provide roadside space for wide high capacity ramps to be built between the Outer Loop and Shirley Highway (I-95 and I-395), without needing expensive right-of-way acquisition of many adjacent homes and apartment buildings; and outboard of its original location east of the interchange, to provide median space for the pair of elevated ramps with the flyover bridges that connect the I-95 through traffic movements between the I-95/I-495 Beltway and I-95 Shirley Highway.

The original Outer Loop bridge over Shirley Highway remained in place with one lane open to carry the loop ramp traffic from southbound I-395 to the Beltway Outer Loop, until the 1-lane flyover ramp from southbound I-395 to the Beltway Outer Loop (toward Wilson Bridge) opened to traffic in October 2005.

Phase 5 of the SIIP involved widening the Beltway west of I-95, relocating the Outer Loop of the Beltway in the I-95 interchange area, and realignment of the ramp from I-395 southbound to I-495 westbound, and widening the Capital Beltway from I-395 westward to near VA-620 Braddock Road. Phase 5 was placed under construction in August of 2001, and was completed in May 2004 at a cost of $95.5 million. 

Phases 4 and 5 of the SIIP included extensive construction of sound barrier walls along the western, southern and eastern edges of the interchange and approaches. Notice the sound barrier walls under construction along the edge of the interchange.

Southbound mainline roadways and ramps have been relocated to provide space to build the southern part of the 2-lane express flyover ramp (the I-95 southbound through route) under construction from the Beltway Inner Loop (from Wilson Bridge) to I-95 south. The elevated ramp under construction is the B-610 bridge that will be that 2-lane express flyover ramp. The B-610 bridge is 4,870 feet long.

Notice in the middle of the photo, the temporary roadway for the Beltway Inner Loop which passes under the southbound I-95 flyover bridge under construction. About 1/4 of a mile of the Inner Loop roadway is being reconstructed for the transition to the flyover, and the temporary roadway is carrying the traffic while the reconstruction is underway.

In the distance is the Beltway bridge over the CSXT and WMATA railroads, and beyond that is the VA-613 Van Dorn Street interchange with the Beltway.

The bridge in the mainline of the Beltway, passes over the 2-track CSXT railroad mainline (which carries freight trains, Amtrak trains, and Virginia Railway Express commuter trains), and passes over the 2-track WMATA Metrorail Franconia/Springfield Route (Blue Line trains). The pre-existing pair of 4-lane bridges is being replaced by a pair of longer bridges that will each have 7 lanes. The new Outer Loop bridge has been constructed, and Beltway traffic is temporarily operating there with 4 lanes each way while the pre-existing Inner Loop bridge is demolished and a new Inner Loop bridge is being built. The replacement of these bridges was tedious due to railroad regulations that limited construction to only a few hours per day. The new bridge (B-635) has 4 spans, one over each railroad, and two to provide storm drainage.  The B-635 bridge is 507 feet long.
