There's a lot of anticipation and excitement about improvement projects coming to Valley freeways after Maricopa County voters approved Proposition 479 last year. The extension of a half-cent tax to fund transportation projects in the Phoenix region means important work will start as soon as next year, building on decades of coordination between ADOT and MAG on freeway construction and improvements.

That's why we're thrilled to have John Bullen, Assistant Executive Director and Chief Transportation Officer with the Maricopa Association of Governments (MAG), join us for this week's episode of On the Road With ADOT. While ADOT will build the projects, MAG manages the funding and scheduling of the improvements under its Regional Transportation Plan.

Listen in as John talks with host Doug Nintzel about what the future holds for enhancing Loop 303 at and around Interstate 17 in the North Valley, , the area around Loop 303 and US 60 (Grand Avenue) in the Northwest Valley, I-10 widening south of the Valley, State Route 347 within Maricopa County and much more. It’s an interesting discussion about how voters have invested in the Phoenix area’s modern freeway system.
