I want to know the answer to the following question:
What is the type of freeway system that serves Houston?
All the background I'm provided with is that "A proposed highway project, State Highway 99 (Grand Parkway), will form a third loop outside of Houston, totaling 180 miles in length and making an almost-complete circumference, with the exception of crossing the ship channel.". Is that enough to answer the question?
Answer: no
