Notes:Arlington Avenue

Source:Weslager: "If you hail a cab in downtown Pittsburgh and ask the driver to take you to Beltzhoover or Allentown, he won't remind you that your destination should properly be referred to as the Eighteenth Ward. He will whisk you across the Smithfield Street Bridge, left on West Carson Street, and up cobbled Brownsville Avenue, one of the city's oldest and steepest streets, now called new Arlington Avenue. At the top of the hill you will intersect Warrington Avenue, the main street of the two former boroughs."

Source:Allentown, p. 27: "Brownsville Turnpike Road (1852) was renamed Pittsburgh and Brownsville Turnpike (1872), Brownsville Avenue (1901) and on May 12, 1927, it became Arlington Avenue. This was the northern section of the main road to Brownsville, Pennsylvania. Brownsville Road was a branch of the National Highway from Philadelphia to Wheeling, West Virginia."
