Friday is the last day for KAT's Farragut Express route.
The Knox Transit Authority approved cutting the route at its meeting this month.
The route has dedicated riders, but it couldn't boost its usage by 50 percent, which was the Town of Farragut's request.
Because of that, the Town of Farragut cut its funding for the route, and KAT chose to end it.
KAT says it is common for support for express routes to fluctuate.
"Express routes are very dependent on what the price of fuel is, or the perceived high or low price of fuel. And right now the price of fuel is perceived to be very reasonable. And so we tend to sort of fluctuate on our express routes based on that," said KAT's Belinda Woodiel-Brill.
Some of the current riders have been riding the express since the route started back in 1999.
