Woodrow Wilson Memorial Bridge
Washington, D.C.

Work on the project began in 2000
and is scheduled for completion in 2008

Woodrow Wilson Memorial Bridge

Located in Washington, D.C. is a 6,000-foot long replacement structure for the original Woodrow Wilson Memorial Bridge.

The twin replacement structures feature deck widths of up to 148 feet utilizing a unique structural system that mimics the arch bridge at other points along the Potomac River.

The concrete v-shaped piers are designed to be built using the pre-cast segmental method. There are four steel girders which sit atop each V-Pier and support a reinforced concrete deck. The 175-foot navigation channel is spanned with an eight-leaf double bascule structure.

  Maryland Department of Transportation
  State Highway Administration

• Contractor: Potomac Constructors, LLC – Maryland Approach Joint Venture of Edward Kraemer & Sons, American Bridge, & Trumbull Corp.

• Type: Segmental Concrete V-piers.

• Erection Method: Temporarily Stayed Cantilevered V-Piers

• Services Provided: Construction Engineering including design of erection equipment and temporary supports for erection of V-pier segments, lift rigging and hitch design, integrated segment shop drawings, design of work trestle and temporary piers and bulkheads.

Troup-Howell Bridge

The new Troup-Howell Bridge, a $38.7 million signature project for the New York Department of Transportation, will be a triple-member steel arch bridge that rises 70 feet above the road surface. When complete, it will also be the widest three-member pure arch bridge in the country. Edward Kraemer & Sons, Inc. is constructing the main span over the Genesee River and the 7 approach spans as a replacement to the original cantilevered multi-girders structures built in 1953. The structure upgrades an important transportation link in the city of Rochester in addition to dramatically changing the city skyline.

The new structure follows the same alignment as the existing bridge. Traffic will be diverted to half of the existing structure while the other half is demolished and the new structural steel is constructed. This involves erecting two of the three arch ribs on a series of temporary props, installing hanger strands and floor beams, and casting a concrete deck. Once complete, traffic will be diverted to the new arch structure and the remaining existing structure demolished. The third arch can then be erected and remaining floor beams and concrete deck completed.

Maumee River Bridge
Toledo, Ohio

Work on the project is scheduled
for completion in June 2006.

Maumee River Bridge

At a construction cost of $220 million dollars, the I-280 Maumee River Crossing is the largest single construction project in ODOT history.

When completed in late 2006, this cable-stayed, precast segmental Signature bridge will carry six lanes of Interstate 280 across the Maumee River in Toledo, and will replace the Craig Memorial Bridge, one of the few remaining lift-span bridges which remains on the U.S. interstate system.

Route 123 Over Occoquan River

Archer Western Contractors began construction the twin, 360m bridges over the Occoquan River in 2003. Each bridge includes a conventional precast bulb-t approach structure.

The main span is constructed using spliced, post-tensioned bulb-t girders. As such, all of the girders are erected on temporary falsework and post-tensioned together to be self-supporting.
