Highways and roadways impact Valley drivers on a daily basis. Valley 101 listeners often submit questions to the Arizona Republic's podcast team to dive into these topics.
In this week's episode of Valley 101, a podcast from The Arizona Republic and azcentral.com, we’re answering three of those questions. 
We'll take a brief dive into the history of Arizona toll roads, a look at the future of Interstate Highway 11 and then how Loop 202 South Mountain Freeway has impacted the Valley.
In this episode you'll hear from: 

Laura Douglas, a communications project manager with the Arizona Department of Transportation

Philip Vandermeer, an emeritus professor of history from Arizona State University

Eric Anderson, the executive director for the Maricopa Association of Governments.
