Why the North Side Is Its Own Journey
Broken Arrow is large enough that getting across it is a real consideration. The city stretches several miles north to south, and the north side sits closer to the expressway and to Tulsa than to the older centre of town.
That means north-side residents often default to driving into Tulsa for services, because the expressway makes it easy. For dental care that is usually the longer trip rather than the shorter one, once you count the traffic at the Tulsa end.
