The Grand Concourse (also known as the Grand Boulevard and Concourse) is a 5.2-mile-long (8.4 km) thoroughfare in the borough of the Bronx in New York City. Grand Concourse runs through several neighborhoods, including Bedford Park, Concourse, Highbridge, Fordham, Mott Haven, Norwood and Tremont. For most of its length, the Concourse is 180 feet (55 m) wide, though portions of the Concourse are narrower.
The Grand Concourse was designed by Louis Aloys Risse, an immigrant from Saint-Avold, Lorraine, France. Risse first conceived of the road in 1890, and the Concourse was built between 1894 and 1909, with an additional extension in 1927. The development of the Concourse led to the construction of apartment buildings (a plurality of six-story high-class semi-fireproof elevator apartment houses was perceptibly interspersed with buildings that ranged from a more affordable tier of five-story New Law walk-up apartment houses to a handful of taller fireproof apartment houses comparable to those on Manhattan's luxury thoroughfares) surrounding the boulevard. By 1939, it was called "the Park Avenue of middle-class Bronx residents". A period of decline followed in the 1960s and 1970s, when these residences became dilapidated and the Concourse was redesigned to be more motorist-friendly. Renovation and redevelopment started in the 1980s, and a portion of the Grand Concourse was reconstructed starting in the 2000s.
