McKinney, Texas is building a $70m high school football stadium

McKinney, Texas, a city of nearly 162,000 people just north of Dallas, is poised to make history for building what may be the costliest high school football stadium in the nation. The price tag? A cool $70 million.

The price of McKinney's new stadium was already astronomical in May, when the New York Times reported estimates had risen to $63 million. Last week, American School and University reported costs had hit a new high of $70 million — and the stadium isn't even scheduled for completion until 2017. The new stadium will replace one built in 1962.

One supporter of the project told the Times she believed the new stadium would host events and attract visitors to McKinney, saying it would bring "thousands and thousands of people coming into our city and spending their money here in our city."

The Texas city was also in the news back in 2015, when a video showing a McKinney police officer body-slamming a 15-year-old black girl at a pool party went viral, spurring outrage.
