The early work of construction on the city’s grand P.O. at the southeast corner of Third Avenue and Union Street was confounded by they city’s decision to regrade Third Avenue the distance from James Street to Pine Street where Third was interrupted and prevented by Denny Hill. The lowering of Third Avenue resulted in the addition of new ground floors for many of the businesses and homes facing Third Ave. Here at Union the new P.O.’s planned front doors facing Third were accommodated with steps t hat reached well into the sidewalk. This sidewalk extension can be found above the trolley approaching Union Street in the right corner of in this photograph.
