Task: Question Generation
Input (English): In Topeka, I-70 intersects a child route, I-470, twice. The second time it is intersected, the Kansas Turnpike merges, making I-70 into a toll road. This is one of only two sections of I-70 that are tolled (the other is along the Pennsylvania Turnpike), with the maximum toll distance costing $17.50 as of 2016. I-70 carries this designation from Topeka to Bonner Springs. It is the eastern terminus of the turnpike, and from there to 18th Street and extending on to the Kansas eastern border, the highway is free.
Output (English): are there tolls on i-70 in kansas?
