Texas State Highway 99 - Future Construction

Future Construction

The next section that will be constructed is Section E, most likely followed by either Section F-1, F-2, or G. All of these sections are located northwest and north of Houston. Section E will run from the northern terminus of Section D north to US 290. Section F-1 will start at the end of Section E and end at the intersection with State Highway 249. Section F-2 begins here and terminates at Interstate 45. Section G starts at the end of Section F-2 and travels to US 59.

Future sections of the Grand Parkway will most likely be built as tollways in conjunction with the Harris County Toll Road Authority to speed up the loop's completion. Western sections of the Grand Parkway have been mentioned as possible bypass routes for the Houston section of the proposed Interstate 69 extension to the United States–Mexico border.
