Eight segments of the planned 107-mile Grand Parkway System are now open, which is part of the SH 99 Grand Parkway Project, a planned loop circling the Houston metro region. Drivers can travel nonstop on the SH 99 Grand Parkway System through the northwest and northeast areas of Houston from I-10 near Katy to SH 146 in southwest Baytown. In addition to helping alleviate traffic congestion in some of the area’s fastest-growing communities, the SH 99 Grand Parkway System provides additional hurricane and emergency evacuation routes for the greater Houston area. Once completed, the planned SH 99 Grand Parkway Project will consist of 184 miles and 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. Need a tag? Sign up with Harris County Toll Road Authority (HCTRA) at hctra.org.

Tag toll rates correspond to Electronic Toll Collection (ETC) toll rates. Tag toll rates effective 1/1/2025. Non-Tag toll rates are calculated by applying a 50% surcharge over the TxTag/Tag rate. The 2-axle Non-Tag toll rates are rounded to the nearest cent. The remaining 3+ axle toll rates are calculated using the 2-axle rates multipled by the N-1 formula, where N is the number of axles. Additional fees apply for Non-Tag transactions. Non-Tag toll rates effective 4/1/2025.
