Crews have put the finishing touches on six white arches across the Anacostia River.

The arches are part of the new Frederick Douglass Memorial Bridge. Set to open late next year, it replaces the existing bridge that carries South Capitol Street from the Anacostia neighborhood to near Nationals Park in Navy Yard.

Just after noon on Thursday, a crane hauled the last piece of into place in the middle arch. A tree stood on the final piece, an old construction tradition that signals “topping out” the highest structural element on a project.

It’s a milestone for the project, which was announced in 2012. Construction began in 2018, on the bicentennial of the namesake abolitionists’ birthday. But, due to inclement weather, there was no ceremony to celebrate the completion—just the view from a live cam through the rain.

Mayor Muriel Bowser, Congresswoman Eleanor Holmes Norton, District Department of Transportation Director Jeff Marootian, and Federal Highway Administration Division Administrator Christopher Lawson were previously scheduled to speak.

In a press release, Bowser said the arches are a beautiful new addition to D.C.’s skyline and a tribute to Douglass.

“The new Frederick Douglass Memorial Bridge represents a bold step forward to build an even more connected DC where residents on both shores of the Anacostia are sharing in the economic prosperity this project will bring,” Bowser said.

The six-lane bridge is one lane wider than its predecessor. The 70-year-old span of the same name is just 100 feet away and carries 77,000 vehicles a day. Constructors will now begin work on paving the bridge deck. The finished bridge will also have two piers that will appear to float in the river and four pedestrian overlooks, according to DDOT. In addition, it will have wider bike and pedestrian crossings.

The $441 million bridge and the accompanying infrastructure, including a reconstructed interchange at I-295 and Suitland Parkway, is the largest DDOT construction project since the department was formed in 2002. The entire South Capitol Street Corridor project cost more than $1 billion.
