Woodrow Wilson Bridge Project Photos - January 2006

The following 75 photos show various aerial views of the I-95/I-495 Woodrow Wilson Bridge (WWB) Project construction, including the new Potomac River Bridge construction, the Virginia U.S. Route 1 Interchange construction, the Washington Street Urban Deck construction, and the Maryland Interstate 295 Interchange construction.

These photos were taken by the Virginia Department of Transportation, and are posted here with their permission. Roads to the Future utilized PhotoDeluxe Business Edition to sharpen and brighten and to align all of the photos. Click on the photo to get a large version of the photo. In later versions of Netscape and Internet Explorer, you probably will need to use Full Screen mode (the F11 key can be utilized to swap back and forth between Full Screen and Regular) to see the full size of the large photo without browser-induced image shrinkage. The large photos have sizes ranging from 80 to 328 kilobytes, with most of them being under 218 kilobytes. With a broadband or network Internet connection each photo will download within seconds, but with a dial-up Internet connection it will be somewhat slower.

The following 37 photos were taken on January 9, 2006, by the Virginia Department of Transportation.

The delta piers on the approach spans are being constructed via the precast segmental method, whereby reinforced concrete segments are cast in a fabrication yard, and assembled on the pier foundations and post-tensioned with steel cables that pass through channels in the piers. The arches are held in place by temporary steel cables until the reinforced concrete cross-member links the two arches. The bridge's steel beams and roadway deck are constructed across the top of the piers.

The metal structure that runs lower-left-to-center, is the cage of steel reinforcing bars ("re-bars") that will form the core of the concrete median barrier that will separate the 3-lane express roadway from the 3-lane local roadway.

I believe that this and the following set of photos that were taken from above the bridge, were taken from the under-construction new drawbridge Operator's Tower.

This is a telephoto view of the top of one of the delta piers. Notice the reinforced concrete cross-member that connects the two arms of one delta pier. The holes in the concrete structure that have steel cables sticking out, are channels through the arms and cross-member for post-tensioning steel cables which will be installed and tightened with hydraulic jacks so as to effectively make the series of segments into one reinforced concrete structure.

The following 38 photos were taken on January 28, 2006, by the Virginia Department of Transportation.

U.S. Route 1 Interchange construction, looking north across Hunting Creek and the I-95/I-495 Capital Beltway, with Alexandria on the north side of the Beltway. This photo was taken from over US-1, and the new ramps can be seen on either side of US-1. The two new southerly ramps connecting the Beltway to US-1 (Outer Loop to US-1 southbound, and US-1 northbound to Outer Loop), were opened to traffic in August and September 2005, respectively.
A new temporary ramp taking motorists from the Outer Loop of the Capital Beltway (I-95 North) to US-1 North into Old Town Alexandria opened on October 25, 2005. This temporary ramp is a temporary bridge, as it connects one bridge to another. It connects the partially-completed permanent new bridged Beltway Outer Loop local roadway, to the pre-existing US-1 bridge, with a new temporary traffic signal between the ramp and US-1. The pre-existing loop ramp for this movement was a bridge structure, and it was demolished afterward.

The Woodrow Wilson Bridge is to the right. The new ramp from US-1 northbound to the Outer Loop of the Beltway, can be seen in the foreground of the photo, and this bridged ramp has a separate pedestrian/bicycle trail on the east side of the bridge, and the trail carries pedestrian/bicycle traffic between US-1 south of Alexandria and Washington Street and the pedestrian/bicycle trail which will cross the Potomac River on the new Woodrow Wilson Bridge to pedestrian/bicycle trails in Maryland.

Mount Vernon Memorial Highway runs from the right bottom of the photo, upward past the apartment complex where the Mount Vernon Memorial Highway becomes Washington Street, and Washington Street crosses the Beltway and goes into Old Town Alexandria. The Beltway runs left-right across the center of the photo.

Looking west along the Beltway, showing construction of the Washington Street Urban Deck in Alexandria VA, and the U.S. Route 1 Interchange in the distance. The new highway's retaining walls close to the buildings are complete, and the Washington Street Deck has been completed over the future local and express Beltway Outer Loop roadways. The west end of the Woodrow Wilson Bridge is visible in the bottom of the photo. The Beltway detour roadway has been completed and traffic was shifted to it. Some of the Hunting Towers Apartments are visible in the left of the photo. This is what it looked like just before the tie-in construction started -- WWB-Aerial-Jun1705-1. With the Beltway traffic shifted out of the way, now construction can proceed on the northern half of the Washington Street Deck, to complete the whole deck.

U.S. Route 1 Interchange construction, looking south along U.S. Route 1 which goes into the distance, with the Beltway running left-right. The original U.S. Route 1 Interchange had a considerable amount of bridgework across areas of water and low-lying land, with a long bridge on US-1 and bridges on four of the ramps. The original interchange opened to traffic in 1961, with a modified cloverleaf design with a semi-directional flyover ramp connecting southbound US-1 to northbound I-95/I-495 (to Wilson Bridge), and with a collector-distributor (C-D) roadway intercepting the two loop ramps on southbound I-95/I-495.

The new ramp is nearing completion, that will replace the original semi-directional flyover ramp connecting southbound US-1 to northbound I-95/I-495 (to Wilson Bridge), and there will be a temporary tie-in between the ramp and northbound I-95/I-495.
