State Highway 121 in Collin, Dallas and Denton Counties


The State Highway (SH) 121 project is a 25.9 mile toll road that will run through Collin, Dallas and Denton counties from McKinney where SH 121 intersects with U.S. 75 west to Lewisville near the Tarrant County line.

In addition to developing and operating SH 121, the NTTA provided a payment of $3.3 billion at financial close to TxDOT; the Regional Transportation Council (RTC) will decide how those funds should be used for additional road projects throughout north Texas.
