Segments H and I-1 are an environmentally approved 37.5-mile, four-lane, controlled access toll road with intermittent frontage roads from US 59 North (the Eastex Freeway) near New Caney to US 90 near Dayton to I-10 East (the East Freeway) near Mont Belvieu through Montgomery, Harris, Liberty, and Chambers counties.

Construction is anticipated to begin Fall 2017 and anticipated to last three years. On March 28, 2017, the Texas Transportation Commission determined the proposal submitted by Grand Parkway Investors provides the apparent best value to the department.
