The Third Avenue Elevated once ran through East Tremont, linking it with Manhattan all the way down to Chatham Square, in what is now Chinatown. The decaying wooden house at 772 East 182nd Street was likely built around the same time as the elevated, in the first few years of the 20th century. After the city suspended the elevated service in the 1950s and ’60s, the area began to slide into abandonment and poverty. But the neighborhood is slowly rebounding with the arrival of small, market-rate construction projects. Yesterday, new building applications were filed for a seven-story, 18-unit development that would replace the old house at 772 East 182nd Street, just west of the Bronx Zoo.
