Interstate Speedway is a 3/10 mile black gumbo high-banked oval located north of Jefferson, South Dakota. This track is sometimes refered to as Interstate 29 Speedway.
The track is in a state of transition, as a new promotor is taking over for 2006 while the previous promotors move to Park Jefferson Speedway on the south side of Jefferson. The official web site is still (as of 1/4/2006) owned by the old promotors. No word on what the new promotor will do for a website (if anything.)
