A couple of reasons I can think of include:
High voltage overhead cable is much cheaper than underground cable
Easier to reconductor (upgrade current carrying capacity)
Easier to find faults

What is the spark plug voltage?
Spark plug voltage is high tension voltage, needed to jump a spark between the plus and minus poles. Needed tension is about a minimum of 10.000 Volt between the poles.
Does voltage on ground mean open ground?
Voltage on ground can mean an open ground. It can also mean (high) current on ground, due to a ground fault such as reversed neutral and ground.
Why are power lines that move high voltage tall?
Because the line conductors are uninsulated, and must be kept at a safe distance above ground level.
What is the minimum value of high voltage?
Well, the word "high" can have different meanings in various work-areas. To an electronics specialist, "high" voltage can be anything above 5-10 V. To a home-electricity-technician, "high" voltage is anything above 50 V. To an electricity-company-technician, "high" voltage is anything above 230 V. It is better to ask for a clarification each time you here the term "high voltage".
Is the drain wire in medium to high voltage applications considered a neutral or ground?
ground
What two features of a high tension cable are designed to ensure electrical safety?
High-voltage cables are usually placed high above the ground. Also, where the cables touch the posts, special insulators are used.
What is a group of dry cells connected together with their positive poles pointing to the same direction?
"series" ... high voltage
Is the temperature of the air high above the ground above or below 0?
ABOVE
What is a group of dry cells connected together with their positive poles pointing to the same direction called?
"series" ... high voltage
What is the meaning of high voltage?
Its arbitrary AND situational ... but most commonly means any voltage above 600 volts.
How do you make a homemade high jump?
You Just Get Two Very Strong Poles (or sticks) stick them into the ground and then tie a thick string across the two poles (or sticks) and then you have your homemade high jump set
How high above ground are you from the Space Needle's observation deck?
The observation deck is 520 feet above the ground level.
