The 1.5-mile, $175 million Tomball Tollway Phase 2 extension will span six lanes just north of FM 2920 to the Harris County line at Spring Creek. The project is expected to begin construction in January 2017 and should be complete in early 2019, said John Tyler, Harris County Toll Road Authority deputy director of engineering.

The next section of Phase 2, which will extend six lanes from Spring Creek to the area near Woodtrace Boulevard in Pinehurst, could begin construction in mid-2017 and should be complete in early 2019, said Danny Perez, Texas Department of Transportation Houston District public information officer.

TxDOT is constructing the remainder of the 24-mile Hwy. 249 extension in two segments—Phase 3 runs from near Woodtrace Boulevard to FM 1774 near Todd Mission and Phase 4 is from FM 1774 to Hwy. 105 near Navasota.

Phase 3 will be constructed as a four-lane tollway, and Phase 4 will include two lanes with an intermittent passing lane. Pending a public hearing in Grimes County, the segments could open as soon as summer 2019, Perez said.
