District and federal officials plan to dedicate a new Ninth Street NE Bridge Tuesday morning, one of five projects along the New York Avenue corridor that have bedeviled commuters along a major east-west route linking the city with the Maryland suburbs.

Mayor Vincent C. Gray, District Department of Transportation Director Terry Bellamy and Federal Highway Administrator Victor Mendez are scheduled to appear at a ceremony Tuesday morning marking the replacement of the 70-year-old bridge. City officials said the old span “had far outlived its service life.”

Construction began in 2009 and was originally scheduled to be completed in spring of this year on the bridge, which provides a link between New York and Rhode Island avenues, across Amtrak and CSX tracks.

New York Avenue commuters, however, still have to contend with the bridge rehabilitation just west of Florida Avenue. That project isn’t scheduled to be completed until 2013.
