A train line temporarily serving the Phoenix metropolitan area was named for her. After a series of floods in February 1980 damaged many bridges crossing the Salt River, traffic was in a state of gridlock. In response, a temporary commuter train line was started between the cities of Phoenix, Tempe, and Mesa, using existing freight track and Amtrak trains. The train line was named the "Hattie B." in honor of the governor and first lady's involvement. The line was cancelled as soon as bridges were restored, but it was credited with creating more interest in public transit for the Phoenix area.[14]
