As Hurricane Rita was making its way through the Gulf of Mexico in 2005, the projected path was towards the Houston and Galveston, Texas area. An evacuation was called for parts of Harris and Galveston counties. Which is where the cities of Houston and Galveston are located.
The way evacuations are “supposed” to work, the areas that are nearest the Gulf of Mexico are evacuated first. Which is Galveston, and lower Harris county. That is how its supposed to work in theory. In reality, how does one of the largest cities in the USA evacuate? They dont. There were stories of people spending 18+ hours on the highway and not even going 10 miles.
There are 2 major highways going north out of Houston – HWY 59 and HWY 45. Going east and west, there is Interstate 10, 1960, old HWY 90 and 105. HWY 105 is north of the Houston area. It goes from Beaumont, through Cleveland, Conroe and finally hits HWY 6.
