Kennywood amusement park announced plans for a new multimillion-dollar roller coaster to open next May.

The steel roller coaster, yet to be named by the park, will launch riders from 0 to 50 mph in less than three seconds using magnetic propulsion technology known as a linear synchronous motor.

The 65-second ride offers two, 90-degree ascensions and drops, three inversions, a corkscrew and multiple "cliffhangers" -- which leave riders feeling weightless at the top of a hill. Riders will be immediately launched into a vertical 95-foot climb rather than a traditional slow climb up the first hill.

The 2,100-foot track will replace the Turnpike ride, which has been in its spot near the park's entrance since 1966.

"Guests aren't saying goodbye to the Turnpike, just saying 'see you later,' " public relations manager Jeff Filicko said in a press conference at the park today. The park will bring the Turnpike back sometime after the 2010 season to a different location.

The new ride's location is also the location of Kennywood's first roller coaster, the Figure Eight -- later known as the Gee Whizz Dip the Dips -- built in 1902.

The Turnpike's last day will be this Sunday, after which crews will begin planning construction for the new coaster.
