One road
Andover to the table runs 6.5 miles on a single street.
Andover sits 6.5 miles from the door by road, and nearly all of that is 21st Street. Point the car west, stay on 21st, and The Shops at Tallgrass shows up on the north side about a fifth of a mile before you reach Rock Road. Allow 12 to 19 minutes, depending on traffic. No interchange, no frontage road, no exit number to keep in your head — you get one instruction and it lasts the whole way.
It sounds like a small thing and it isn't. A drive with four decisions in it costs you attention even when it's short, and it costs you more of that on the way home, in the dark, with your shoulders finally loose. This one asks for none. And a first visit needs no rehearsal — if you've driven into Wichita for groceries, you've already done the hard part, which is knowing which street to be on.
The band is wide because the drive really does swing. Its low end is the run where the lights fall your way, its high end is the run where they don't, and almost all of that gap shows up in the last stretch, not out on the open road. The 21st and Rock arrival guide covers the turn into the lot, the suite number and where to leave the car once you're there.
