PHOENIX (KPHO/KTVK) - Crews began demolishing the first of hundreds of Ahwatukee Foothills homes in the path of the new South Mountain Freeway Thursday morning...near 24th Street and Pecos. Most had no choice but to leave, but despite the arrival of bulldozers, a few homeowners say they still aren't moving.
For more than 20 years, the Arizona Department of Transportation has been acquiring the right of way for the South Mountain Freeway, including homes and businesses that could be in the way.
Some people who live in these neighborhoods have repeatedly tried to stop the project from going forward. Nearly 200 vacant properties currently owned by the state will be cleared from the area in advance of freeway construction, which is scheduled to start next summer.
