A late December visit to Six Flags Over Texas shows the rapid progress being made on the demolition of the La Vibora bobsled roller coaster. The last of its kind, La Vibora had operated at the park since 1986. Its removal is part of new investment, which is highlighted by a record-breaking dive coaster to open in 2026. We also check out how other rides are affected by the demolition, including the Six Flags Railroad.
