Houston is often criticized for lack of long-term planning, particularly due to its lack of zoning which allows organic growth.
Reports reveal that Houston's third beltway, Grand Parkway, was initially planned back in 1961 when the city's population was much lower at 1.2 million people.
The construction of the Grand Parkway began in 1994 and is still ongoing to complete the longest beltway in the US, covering more area than the state of Rhode Island.
Houston's success may be attributed to its macro-scale planning approach that looks far into the future while allowing flexibility and minimal micromanagement.
