Segments F1, F2, and G total approximately 37 miles in length and run through Harris and Montgomery Counties. The project consists of over 9 million cubic yards of earthwork, more than 100 bridges and associated drainage, as well as utility infrastructure. The overall Grand Parkway is a proposed 180-mile highway crossing seven counties in the Greater Houston Area.

Segment F-1 is a 12.1-mile, four-lane, controlled access toll road with intermittent frontage roads from US290 to SH249 through northwest Harris County. Segment F-2 is a 12.2-mile, four-lane, controlled access toll road with intermittent frontage roads from SH249 to IH45(N) through northwest Harris County. Segment G is a 13.5-mile, four-lane, controlled access toll road with intermittent frontage roads from IH45(N) to IH69(N)/US59(N) through northeast Harris County and southwest Montgomery County. The three segments were delivered as a single design-build project that began construction in July 2013 and opened to traffic in March 2016.
