On January 11, 1999, Postiglione was struck in a hit-and-run by a passing motorist as he was exiting his truck to repair a catch basin at this location.[1] He died of his injuries 11 days later.[2] His murderer had never been identified. On October 20, 2000, Mayor Rudy Giuliani signed legislation renaming the traffic triangle at the site of the hit after Postiglione.[3]
The acute end of the triangle contains a small monument for Postiglione donated by his labor union, DC 37 Local 376. Within the triangle is a single tree, surrounded by shrubs. On the Horace Harding side of the park is a bus stop on the eastbound Q17 and Q88 routes.
