I never knew they had those slopes either (must be the rarest parts in that style). On a side note: That same Jeremy set was my very first exposure to the TOMY road system, as that was before I got the Ultimate Set.
Even though the TrackMaster road has the same style of connection as the track, it is slightly wider and therefore can't connect.
