As one of the nation’s oldest cities — founded in 1638 — New Haven has changed many times and in many ways over the years. Among the areas of the city that have changed significantly over the past few decades are Downtown New Haven, the area around Wooster Square, the Dixwell Avenue commercial district and Long Wharf. New construction also is rising — at long last — on the longtime parking lot that once was the New Haven Veterans Memorial Coliseum before it was demolished in 2007. Dixwell Avenue — the Main Street of the city’s Dixwell and Newhallville sections, with a storied history as a mid-20th Century jazz mecca and center of African American commerce and culture — is another part of New Haven that has seen some of its major past efforts at revitalization, including the Dixwell Plaza shopping center, run their course and become targets for redevelopment.
