The former Studebaker Proving Ground is located eight miles west of South Bend, IN on Indiana State Road 2, or Western Avenue on 850 acres.  Built in 1926, during the last two years of World War Two, it was a contracted test track for the US Army Ordnance Department and many non Studebaker military trucks and halftracks were tested at this location. 

The US Army Ordnance Department signed a contract with Studebaker on March 29, 1943 for the use of the facility as a military vehicle test ground.  The US Army Corps of Engineers immediately came in and converted the grounds for the military testing which began on June 20,1945.  As the war started to wind down, the contract was terminated on June 30,1945, and the Proving Ground returned to Studebaker for civilian testing.

 Bendix, another company based in South Bend, took possession of the Proving Grounds on June 1, 1966 after Studebaker went out of business.   Not long afterwards Bendix donated 175 acres of the original 850 acres to St. Joseph County, which is now known as Bendix Woods.  Today the proving grounds are still in operation, but owned by Bosch.  

The Studebaker Proving Ground looking south, southwest.  At the center bottom are the garages, which are still there and retain the "S" for Studebaker on them.  Just to the right is what is known as the Clubhouse.  The "S-t-u-d-e-b-a-k-e-r" sign was originally spelt out by 20,000 pine trees and was done in 1937 by the Civilian Conservation Corps.  Each letter is 250 feet tall and the sign extends for a half a mile.  The intent, when conceived in 1937, was to make it the world's largest sign.  Today, if one looks at a satellite photo of the Proving Ground, the tress still spell out "Studebaker".  SR 2 is at the bottom of the photo.

This early photo appears to be an open house, with tents and cars parked on the grounds.  In this case one is looking northeast with SR 2 being at the top of the photo.  The garages are on the right and the clubhouse on the left.

The Clubhouse today, looking south, southwest.  Behind the building are the trees that spell out "Studebaker".  The Clubhouse was originally built to house employees of the Proving Ground that did not want to make the long trip back to South Bend each evening after work, especially in the winter when SR 2 was not plowed by the state highway department.  In reality, the employees made the trip and the clubhouse was under utilized for its original purpose.   Author's photo.

During WWII, it served as a barracks for the US Army officers that were stationed at the Proving Ground.  Today the building is a Nature Center for the park and can be visited.

Looking east through an opening in the fence that divides the park and the Proving Ground, one can see the garages Studebaker built with the "S" for Studebaker on them.   Author's photo.

Looking northwest.
