New York's Coney Island has opened its first new roller coasters since the famed Cyclone was built in the 1920s.

Mayor Michael Bloomberg helped launch four new thrill rides Wednesday. They're known collectively as the "Scream Zone."

The rides operate alongside the Luna Park rides that opened last year.

They're part of the city's renewal plan. The amusement park by the Brooklyn boardwalk had fallen into disrepair over the years.

The city has contributed more than $6 million toward the cost of the new rides for Luna Park and Scream Zone.

The mayor predicts this summer will draw the biggest number of visitors to Coney Island in more than a half century.
