Transitions between road types that required two transition blocks, plus two block variants.

Included:

• Tech to Dirt 2x
• Tech to Ice 2x
• Dirt to Bump 1x and 2x
• Dirt to Ice 1x and 2x
• Bump to Ice 1x and 2x

This set also includes clip removers based on the road to flat blocks. These aren't required though, given the game's clip design (the items will cover up the clips if clip removers are not used).
