HOUSTON, Texas (KTRK) -- An organization dedicated to saving the Astrodome appears to be headed back to the drawing board after years of failed proposals to redevelop the iconic stadium. The Astrodome Conservancy is asking companies to submit ideas for "adaptive reuse and redevelopment" of the Astrodome. Eyewitness News reached out to all four Harris County commissioners for comment on the Astrodome's future, but didn't hear back.
