Changes

Construction on Test Track’s interior track began on March 4, 1996, with the exterior finished 25 days later. Although construction of was continuing on schedule, problems with the attraction’s tires (which could not withstand the rigor of the ride) and the computer system, led to major setbacks. Despite this, on October 28, 1996 a single car test run was held. On February 14, 1997 the show instillation was complete; however when May rolled around Test Track was still not open. In fact the only change that guests could see was that the "Opening in May 1997" sign was changed to "Opening Soon".

By 1998 Test Track was still not open, but the concept art and videos shown in the Test Track Preview Center were updated. Guests also began to see Test Track merchandise available at a cart outside of the pavilion, as well as throughout the rest of Epcot. Finally, in December of 1998 the ride was complete. At this time, the large mural on the outside of the building was removed, and soft openings for guests and cast members began. Although complete, Test Track broke down frequently, and took a long time to restart. This pushed back the opening of the attraction once again, this time to March of 1999.

After three years of construction, Test Track was officially dedicated on March 17, 1999. On hand for the event were NASCAR driver Richard Petty and supermodels Christine Brinkley, Angie Everhart, Carol Alt, and Frederique. Musical bands Earth, Wind and Fire and The Spinners played as fireworks flew over Epcot.
