As a metropolitan area grows, changes, and ages, so does transportation in the region. Transportation, in turn, affects the economy, the environment, safety, and more. That’s where Metropolitan Planning Organizations (MPO) come in to play. Federal law requires that urbanized areas with populations of 50,000 or more have an MPO to carry out metropolitan transportation and programs. The Mid-Region Metropolitan Planning Organization, or MRMPO, is the MPO for the Albuquerque Metropolitan Planning Area.
