West Farms, in the central Bronx, has long been neglected and forgotten by the city. Robert Moses rammed the Cross Bronx Expressway through the area half a century ago, isolating a broad swath of working class communities from the rest of the borough. And the Bronx River, which splits the neighborhood in two, was contaminated by industrial runoff and filled with trash until community groups began cleaning it up the late ’90s. But developers are finally starting to look closely at the working class, black and Latino neighborhood. Mikjor Shllaku, who heads a plumbing company next door in Van Nest, hopes to build a seven-story apartment building at 2015 Vyse Avenue.
