Over more than half-a-century, Elm Street has been resurfaced several times; street lane stripes have been relocated; sidewalk lamp posts have been moved and added; trees, bushes and hedges have grown; and some traffic sign locations have been changed, relocated or removed. On November 22, 2003, the 40th anniversary of JFK assassination, the city of Dallas approved construction project plans to restore Dealey Plaza to its exact appearance on November 22, 1963. The first phase of the restoration, which spent $700,000 for repair work and plumbing along Houston Streets, was completed on November 22, 2008, the 45th anniversary of JFK assassination.
