The Indianapolis Motor Speedway (IMS) announced plans
for the inaugural Red Bull Indianapolis GP motorcycle
race, the first event of its kind to take place since 1909.
To accommodate the event, IMS needed to modify the
existing 2.6 mile road course, which required Dry Run
Creek to be rerouted.
The Speedway was in need of a structure to enclose the
creek beneath the new race track. Critical to the project,
however, was the timeframe in which the structure needed
to be completed. Delivery and installation would need to
begin the first week of September. IMS also required that
installation of the structure be complete by the end of October, so racetrack paving could begin
before winter weather set in.
The Speedway was originally looking at a twin concrete box for the enclosure, and hydraulic
modeling was even performed on the option. However, IMS soon saw that its tight time constraints
would not be conducive to a precast or cast-in-place option. Contech proposed an aluminum structure, which could be fabricated, delivered, assembled and installed in time. Use of an
aluminum invert instead of a cast-in-place foundation would also provide time savings.
The twin structure was produced in about one month. Both boxes have two elbows to
accommodate a necessary curve. The majority of the structure will have a parking lot over top of it,
while a portion will support a section of the bike track. IMS planned for all of construction inside the
facility to be complete in time for Opening Day of the 2008 Indianapolis 500 in May.
