Collin County Toll Roads Often Mean an NTTA TollTag

Collin County driving often means NTTA toll roads. The Sam Rayburn Tollway reaches from Business 121 near the Dallas/Denton county line to US 75 in Collin County. The Dallas North Tollway reaches Plano, Frisco, and Prosper.

Payment works two ways. TollTag customers get lower rates. Drivers without a TollTag get a ZipCash bill by mail at the higher rate.

If you commute through Frisco, Plano, Allen, McKinney, or the US 75 and SH 121 area, set up toll payment early. Bills follow the vehicle record, so an old address or recently sold vehicle can make a small toll harder to unwind.
