Extensions to Bladensburg Road were debated again in 1908, and failed. The right of way was purchased in 1914, and property owners along the street route assessed for construction. But no construction occurred. An extension was proposed to South Dakota Avenue NE in 1925 (after land was purchased to found the United States National Arboretum), but these proposals were not acted on. Construction on New York Avenue Extended finally began in September 1930. The $231,000 ($ in dollars) project created a roadway long from Florida Avenue NE to Bladensburg Road NE. There were no intersections with side streets, and only 4th Street NE merged with it. New York Avenue Extended opened on November 2, 1931.
