Initially, the organization formed in 2002 was called the Highway 3 Economic Development Association. In 2016 the name was changed to reflect the goals of the organization to the "Highway 3 Twinning Development Association". 


On behalf of southern Albertans, the Highway 3 Twinning Development Association will promote and work proactively and constructively with Provincial and Federal governments for the purpose of twinning Highway 3 from the British Columbia border to Medicine Hat at the earliest possible date!
