Construction of the 1890 bridge led to extensive new development east of the river. As the bridge was being built in 1889, a consortium known as the Bliss-Havemeyer Syndicate purchased of land in the former East Washington Heights development. They built a number of roads in the area, and landscaped the plots along Pennsylvania Avenue SE, Alabama Avenue SE, and Branch Avenue SE with gardens, orchards, pavilions, and shade trees. In 1903, Colonel Arthur E. Randle formed the United States Realty Company, bought out the Bliss-Havemeyer Syndicate properties, and founded the settlement of Randle Highlands. In 1902, Randle won approval from Congress to lay streetcar tracks across the Pennsylvania Avenue Bridge. By 1905, he had extended his line down Pennsylvania Avenue SE into the new Randle Highlands. The streetcar line over the bridge spurred extensive new development east of the river. Randle began selling lots in Randle Highlands at a brisk pace in 1903. He made so much money that by 1905 he formed the development of "North Randle Highlands" (now the neighborhoods of Dupont Park, Penn Branch, and the lower portion of Greenway), which extended to Massachusetts Avenue SE. In October 1906, "The Washington Post" called Randle's developments "among the largest real estate enterprises ever successfully carried through in the District."
