A rider died and four others were hurt Monday on Goliath at Six Flags Over Georgia. Six Flags then closed nine similar hypercoasters at six parks.
Carowinds in North Carolina closed Fury 325 and Thunder Striker.
95 mph top speed makes Fury 325 the fastest closed ride.
Police identified the man as Hassan Jihad Ibn Kariem, 42, of Atlanta.
Eight of the nine closed coasters were built by Bolliger & Mabillard.
Why it matters: The closures hit flagship rides at parks across the U.S. and Canada during fall operations. The cause of the Georgia incident is still unclear.
Bolliger & Mabillard also built Goliath in Georgia.
La Ronde in Montreal shut its own Bolliger & Mabillard coaster.
