West of the White Tank Mountains in Buckeye, there's a 30-mile, four-land highway that connects Interstate 10 in the south to Bell Road in the north. It was once seen as the key to city growth, anchoring dozens of future master planned communities and some 300,000 anticipated residents.

This week's episode of Valley 101, a podcast from The Arizona Republic and azcentral.com, digs into the rich history of Sun Valley Parkway.
