A test installation of a levee has closed part of 17th Street in Northwest, D.C, Friday, according to the National Park Service.

NPS has closed 17th Street between Constitution Ave NW and Independence Avenue SW until about 4 p.m. Drivers, pedestrians and cyclists are being asked to find alternative routes.

This is an annual closure and is necessary to make sure the levee can be erected properly when there is high water, NPS said in a release.

A National Parks Service spokesperson said the idea was hatched after flooding in June 2006 damaged to the Department of Justice Building, the National Archives and the IRS building, among others in the Federal Triangle.

The US Army Corps of Engineers operates the levee. It is maintained by NPS.
