Spiral (bobsleigh, luge, and skeleton)

Twenty years since the Nagano Olympics was hosted, various equipment like the electronic display board, refrigeration and lighting systems are needing to be replaced due to obsolescence and wear.

During construction, rocks and trees that were dug up were used as materials to build settling ponds and a retaining wall to prevent landslides.

About 40,000 saplings, mainly beech and oak, were planted two per square meter, as part of the environmental stewardship committed during the Winter Games.

[1] To help with ice making techniques, Nagano Organizing Committee officials recruited Ralf Mende, who works for the bobsleigh, luge, and skeleton track in Altenberg, Germany[5] to train staff to make proper ice.

[1] Mende and his crew worked 18 hours a day during the 1998 Games to ensure track thickness was 2–3 cm (1–1 in) of ice.

[5] There are a total of 56 sensors located throughout the track to maintain constant ice temperature and thickness.
