Back when Norfolk, Va., journalist and author Earl Swift was kind enough to participate in a mighty fun Belligerent Q&A here at the blog, I promised a more serious craft talk with him would follow.

This is it, starting below, and it couldn’t come at a better time.

His new film, in which anthropomorphic cars engage in an international spy adventure, has earned nearly $287 million at the international box office. This, despite the regrettable preproduction death of Paul Newman and the doubly regrettable continued involvement of Larry the Cable Guy, whose every utterance is the tonal reproduction of the sound a banshee makes when kicked in the throat. Oh, wait.

Yeah, I’m think of that new Pixar money grab. Swift wrote a terrific book that is 100 percent Larry the Cable Guy free.

His The Big Roads: The Untold Story of the Engineers, Visionaries, and Trailblazers Who Created the American Superhighways, had its latest strong review in The New York Times this weekend.

Swift, formerly of The Virginian-Pilot newspaper, is also author of Journey on the James, Where They Lay, and The Tangierman’s Lament and Other Tales of Virginia. The Big Roads also has received favorable reviews in The Washington Post and The Wall Street Journal.

And, by way of full disclosure, Swift and I are friends. Without further ado …   

Q: Can you talk about how (The Big Roads) came about? What got you interested in the interstate system as a history?

Well, I’ve always loved road trips, and I’ve always been a bit of a techno-geek; I could identify most airliners by name, model number and manufacturer by the time I was ten, and could ID close to every tank used in World War II at 11 or 12. I could name pretty much every country on a globe, too. Some kids play sports; I memorized cubic yards of weird, arcane, seemingly useless crap.

I was fascinated to learn, at about the time I was perfecting my knowledge of tanks, that the interstate system boasted a numbering protocol, and I made it my business to commit some of the principal routes and numbers to memory. This was completely extraneous to my needs: I was years from getting my driver’s license; even when I got it, knowing such stuff came in handy only once in a very great while. Mostly, it occupied brain space that I would have done well to reserve for other matters. Calculus, for instance.

Fast-forward 30 years, and I’m watching a TV meteorologist serve up the morning weather, and I notice that his map of the Lower 48 has been reduced to its barest essentials—a few cities, the boundaries of the various states. And lastly, the interstate highways. At one point, any national map would have included principal rivers and mountain ranges. No longer: It features no topography at all.

It strikes me that I’ve come to see the country the same way, as a grid of high-speed roads. And that ushers a chain of mini-epiphanies: In the supermarket, I realize I can buy fresh asparagus and clementines and strawberries the year round; that a widescreen TV sells for about the same price in North Platte, Neb., say, as it does in New York; that Virginia Beach, the ultimate bedroom community, a quiltwork of subdivisions that covers a couple hundred square miles, was swamp and truck farms until the 1970s. Superhighways — the efficiency and ease of movement they offer — are the reason for all.

Not long after, I’m talking to an editor at Houghton Mifflin, an incredibly smart and gifted guy named Eamon Dolan. He’s been reading a proposal of mine in which I’ve pitched an entirely different book, and suggests that I instead tackle the interstates. It occurs to me that I’ve been preparing for the story. So I say: ‘OK.’

Q: There’s a great deal of history that coincides with your present-day reporting in Journey on the James, Where They Lay, and now (to some extent) this project, as well as some of your narrative features for The Pilot. What is it that draws you to history?

Living in Virginia, and especially in Norfolk — which has been settled since the 17th Century, and where every piece of property has been used and reused several times over — it’s hard to ignore the notion that our individual stories are part of a greater, never-ending narrative, and that each individual story is affected by those that came before and reverberates in some way to affect what comes after.

I find it reassuring, this idea that we’re all connected through time — that the environment in which we pass our days in 2011 is no accident, but the sum of human enterprise over centuries. And that each of us, however big or small our lives might seem, leaves a mark.

Q: This clearly was a very research and reporting-intensive project. Would you please talk about how you began this process? How did you determine where to gather records, and what was that process like?

In that it was Eamon’s idea, I had to figure out what the story was — like most Americans, I assumed that the interstates were a product of the Eisenhower administration, and that they were largely a civil defense project. It took about 18 months to figure out that they really dated to the 1930s, and were based on ideas that harkened a lot further back than that.

I started by reading everything I could get my hands on that had been published before, from Caro’s The Power Broker to Phil Patton’s Open Road to Jane Fisher’s Fabulous Hoosier. From there, I moved on to academic journals, then magazines. I was well aware that a book about an inanimate object, no matter how huge or compelling that object might be, wasn’t going to fly, so most of that early research was aimed at identifying a handful of characters through whom I could tell the object’s story.

Eventually, I had four main players. Carl Fisher, a wild man from Indianapolis, would get things started: In 1912, he proposed the first coast-to-coast motor road, the Lincoln Highway, and in so doing inspired the creation of a primitive, mostly dirt web of privately sponsored ‘auto trails’ in the teens and early twenties — the country’s first interstate road network. Thomas MacDonald, a preternaturally uptight engineer who led the U.S. Bureau of Public Roads, turned that network into a rational, numbered system in the late 1920s, then oversaw the research and assembled the policy that yielded the concept of interstate expressways in the late 1930s. Frank Turner, MacDonald’s quiet, teetotaler protégé, took that concept and translated it into concrete and steel in the 1950s and 1960s. And Lewis Mumford, a writer and amateur urban planner, was among the first proponents of what we now know as limited-access superhighways, then evolved into their harshest critic — and in both roles helped shape what we got.

I fleshed out all four through their papers, which are kept by university libraries scattered around the country, and through their families, who supplied me with letters, photos and such. I wound up with more than 10 cubic feet of papers.

I didn’t settle on the last main character, a Baltimore homeowner named Joe Wiles, until six months before I finished the first draft. I knew I needed a character who represented the thousands forced from their homes when interstate highway construction ventured into America’s cities, but considered several cities as the setting for that drama before settling on Baltimore. Even then, I had another character in mind — Barbara Mikulski, now a U.S. senator, who by reputation helped lead the fight against the concrete juggernaut. The senator’s staff repeatedly promised that I’d get face time with her, and repeatedly failed to deliver. That turned out to be a favor to me: My research was to show me that her leadership of the fight has been overstated. In her place, I chose Wiles, who was in the thick of Baltimore’s ‘Road Wars’ from the start.

Q: I’ve always been impressed at your early research. What I mean is, you seem to have always done a lot of homework before picking up the phone to do interviews or heading to a location to report or pull records. Can you talk about preparation and planning in reporting?

Interviewing is an organic process. The more you know, the better your questions will be, and the better your subject’s answers will be — which will yield better follow-up questions, and enable the two of you to get into territory you’d never reach if you, the reporter, came into the conversation knowing nothing.

But beyond that, it’s a question of respect. You’re asking somebody to give you something you want but don’t have. It establishes that you value that gift, and that you’re serious about putting it to its fullest possible use, when you’ve done your homework beforehand. Fail to do it, and you broadcast to your subject that he or she is of little importance to you.

I’ve heard some journalists say they don’t prep ahead of an interview because they don’t want to be ‘tainted’ by research. I think anyone who suggests that winging it beats preparation is a fool.

Q: Could you talk about how you organized the narrative? Did you do a lot of outlining? Did you plan out the ways you foreshadow some of the events that take place later in the narrative, such as the events in Baltimore, or does that tend to take shape naturally?

I did do a lot of outlining. I’m a bit of a freak for structure: I believe that it dictates whether a story works. The skeleton is key: Pretty words are all well and good, but they’re like nice skin — they can’t obscure the presence of ugly bones.

This book’s structure morphed substantially over the three drafts I took it through. Initially, I had all five main characters making their first appearances early on, and kept the narrative threads braiding through the whole story. My editors at Houghton, who were terrific, suggested that instead I should introduce each character at the point at which he reached prominence. I wound up with a hybrid of the two structures, in that I had some of the characters make cameos ahead of their full-on entries.

At one point, I was all but committed to using Washington, D.C., as my setting for the freeway revolt. I liked the idea that the protests there occurred within sight and earshot of the guys pushing the highways into town. But Baltimore came to make more sense to me, because it was the example that the Bureau of Public Roads used, back in the 1930s, of a city that would benefit from the interstates — and as things turned out, it’s one of the few major cities in the country that is not penetrated by them.

Q: You demonstrate very clearly that Eisenhower was not the father of the interstate system, and that thought is a kind of mythology. Was this something you understood going in, or did it come in your research? Have you had any feedback on this aspect of the book? It seems like something that would be widely known to engineers, let less so in popular memory of the interstate system.

I didn’t understand it going in; the research made it plain. It’s funny: A good many highway engineers know of Toll Roads and Free Roads, the 1939 report that served as a rough draft for the interstates. They know of Interregional Highways, the report that amounts to an actual blueprint of the system, and in response to which Congress authorized the network in 1944. Still, if you were to ask them, whether employed by the federal government or the states, who is most responsible for the system, a bunch would answer, ‘Eisenhower.’

Q: The placement of this discussion isn’t exactly a revelation, as it is mentioned briefly early on (7), but it’s meat comes roughly 150 pages in, after you have demonstrated the fathers of the system – “career technocrats” – laying out the groundwork. That was an interesting choice that seemed very natural when I reread the selection in the context of the earlier chapters. Then you reinforce it at least two or three times by noting Ike’s absences on major policy events involving the highways.  Can you talk about how you determine what information supports what is a fairly major point, and how you decided to lay it out within the text?

Insofar as this is the story of how the highways came to be, and not a hatchet job on Ike, I didn’t see much need to burden the reader with an opening rant over his being given unjust credit for the interstates early on. I laid out the story in a fairly straight, chronological line, and built a case for who really authored the system simply by relating their acts in the order they occurred; by the time you come to Ike, it’s quite apparent that he’s arrived too late to play a substantial role.

Q: One cost of the highway system in urban areas was the removal of people in slums and struggling neighborhoods to make way for roads. You mention this issue throughout the book, even stressing that urban renewal efforts involving highways target neighborhoods but fail to address the human toll. One of you most compelling examples of the human cost is in Baltimore, where the effect of a planned highway is shown through a middle class black community. What led to this choice? What was it about Joe Wiles and the Rosemont community that led you to use them to illustrate a larger point?

The main argument for Baltimore, from a storytelling standpoint, is that it was the hometown of Herbert Fairbank, who wrote the bulk of Toll Roads and Free Roads and was the ideological brains behind the interstate system. Fairbank used Baltimore in the report as an example of a central city wasting in blight, choked by traffic on colonial-era streets, and losing population and influence to its suburbs—then proposed that encircling the city with a beltway and penetrating its heart with a spray of radial expressways might not only unclog its arteries, but provide a handy tool for clearing slums.

Baltimore was thus the first city of the interstate age, the test case. For my purposes, it was all to the better that it’s also a pretty cranky place, and that the interstates envisioned for it were met with 30 years of protest so harsh that the plans were ultimately abandoned.

Q: Were you aware of Thomas MacDonald and the role he played shepherding the interstate system before you worked on the book?

I’d never heard of the guy.

Q: Though you discuss the shortcomings of engineers behind the system, and unintended consequences of the system, you seem to have an appreciation for Frank Turner, who lost property to a highway and simply accepted that his parents would have to move for a road project – and never used this fact to gain favor or understanding in his role with the system. And then there’s a really poignant moment toward the end of the book that I don’t want to spoil for those who have not read it. Turner, as much as anyone in the book, seems fully realized as a character within the narrative – yet he is someone dramatically different and perhaps harder to bring to life than a showman and businessman such as Carl Fisher. How did you find these stories in your reporting and decide how to deploy them?

As you suggest, Fisher was easy—the guy was a total maniac, each of his ventures bigger and scarier than the last, his every word grist for the newspapers. He was way beyond a risk-taker; he could be downright reckless. That said, he was no dummy, and he had great instincts. I had a lot of fun digging into his past.

Writing about someone who lives a comparatively quiet and careful life is always tougher. Frank Turner was especially so, because he was so damn good — a man whose heart was almost always in the right place, and who didn’t think too much of himself, and who was a loving and responsible husband and father, and who was good at his job and decent to the people who worked for him.

Lucky for me, he left a hell of a paper trail, along with three children and a large number of friends and colleagues I was able to interview. He also sat for several long interviews, the transcripts of which were in his papers at Texas A&M. They were invaluable.

Creating a real character out of him — and of Thomas MacDonald, for that matter — relied on inculcating the reader with an engineering mindset. I hope I was able to pull that off. Engineers get a bad rap as overly sober, numbers-driven, careful. The best of them are, in fact, enormously creative. They’re puzzle-solvers.

Q: I understand you have some magazines stories in the works, as well as another book. Will you please talk about what you’re working on?

I’m halfway through a book about a local man named Tommy Arney, and his struggle to restore an old car. There’s a lot more to it than that, but I don’t like to talk up a project until it’s farther along. I have another book in the outlining stage that’s completely unrelated to cars or transportation — it’s set in the Deep South in the 1910s and 1920s.

Besides that, I’ve been writing for Popular Mechanics and doing a lot of radio interviews. Not least, by any means, I’ve been finishing an MFA in nonfiction at Goucher College; I’ll be heading up to Baltimore to collect my degree in August. What a great program. I’m going to miss it.

After that, I hope, I’ll be back to writing full-time.
