Understanding Fort Worth's geography
Why Fort Worth's drive times defy radius math.
DFW International Airport's vast footprint creates a dead zone in the northeast quadrant — sites in Alliance or Keller see their northeastern isochrones end at the airport perimeter, which eliminates Coppell and Irving from their trade area despite those cities being only 12-15 miles away as the crow flies. The Trinity River floodplain through downtown adds minor bridge-delay constraints that clip the SE isochrone for Sundance Square-area sites.
The Alliance Town Center area along I-35W at Heritage Trace Parkway is Fort Worth's fastest-growing franchise corridor, serving the booming North Fort Worth master-planned communities and the industrial/logistics workforce around Alliance Airport. TCU/Hulen corridor on the south side and the Burleson/Crowley US-174 corridor to the south are emerging markets where residential growth has clearly outpaced franchise supply.
