While for many years, the Hardy Toll Road never had the traffic that the HCTRA envisioned it would need to turn a profit, the Sam Houston Tollway has more than made up for the lost revenue. The high profit margins on the Sam Houston Tollway allowed the authority to construct its third and fourth toll roads, the Westpark Tollway and Fort Bend Toll Road, both of which opened in 2004. Both of these toll roads have termini in Fort Bend County and are run in conjunction with the Fort Bend County Toll Road Authority. HCTRA also operates managed lanes that run along the median of I-10/Katy Freeway between SH 6 and I-610 that opened in April 2009. The most recent project of HCTRA is the Tomball Tollway, which was completed in phases between 2015 and 2019.
