Six segments of the planned 184-mile Grand Parkway (State Highway 99) loop circling the Houston metro region are now open, and drivers can travel nonstop through the northwest side of Houston from I-10 near Katy to I-69/US 59 north of Houston. In addition to helping alleviate traffic congestion in some of the area’s fastest-growing communities, the Grand Parkway provides additional hurricane and emergency evacuation routes for the greater Houston area. Once completed, the Grand Parkway’s 11 segments—designated A through I-2—will travel through seven counties.
All tolls are collected electronically on the Grand Parkway. TxTag, EZ TAG, TollTag, K-TAG, PIKEPASS, and METRO HOT Lanes Toll Tag are all accepted. Please keep your toll tag installed on your windshield and ensure your account information is up to date, including your license plate number, so that toll charges can be correctly applied to your account.
