Highways – loosening our collective belts

Even as the national discussion turns toward whether we are overbuilding highways, based on inflated state traffic numbers, in North Carolina those questions are rarely heard. Last month the state’s largest city, Charlotte, population 800,000, where I live and work, saw the June 5 opening of the final leg of its loop highway.  It’s called Interstate 485 but it doesn’t touch another state, or even another county.

When the road was first discussed in the 1960s, the idea was to open more land for development, because in these parts, the growth-is-good mindset has not had much nuance to it. While the local news media saw headlines such as Last I-485 segment will be boon to locals, we at the UNC Charlotte Urban Institute, where I work and direct the PlanCharlotte.org website, decided to look deeper.

We’ve published some interactive maps that show just how much of the county’s development has been shaped by the outerbelt highway here. A couple of images are reproduced below but find the interactive and zoomable versions at this link.

 In coming weeks we’ll map population growth and traffic counts at the interchanges.

Obviously this is a fast-growing metro area, and growth was going to arrive regardless of where we put our freeways. The questions were: Where was the growth going to go? Can the highway capacity keep up with the demand created by the new development?

 The answer to the first question is now obvious. The growth flooded to the highway, leapfrogging closer in areas that even today lack for investment.  Would even more growth have leapfrogged into adjacent counties without I-485, or would the lack of the highway access have kept the development closer to the core? Who could tell?

The answer to the latter question remains unclear, although I certainly have my doubts. Even before the final link of the loop opened June 5, last December the first leg of the highway, which opened in the 1990s, was expanded from two to three lanes each direction, at a cost of $83 million.

It’s still clogged.

High growth city = poorer city?

I came across an intriguing new study, courtesy of the HoustonTomorrow website, which headlined it, “Fast metro growth =lower incomes: Study links poverty, growth.” The study itself, “Relationship between Growth and Prosperity in 100 Largest U.S. Metropolitan Areas,” by consulting firm Fodor & Associates, looked at the fastest-growing and slowest-growing U.S. metro areas 2000-2009, and looked at per capita income, unemployment rate, and poverty rate. It found that faster growth rates were associated with lower incomes, greater income declines, and higher poverty rates.

Charlotte-Gastonia-Concord and Raleigh-Cary were among the fastest-growing metros the study looked at – no surprise. The report’s writers say it throws some cold water on the often-stated belief on the part of many elected and business officials that growing fast is an automatic route to prosperity.

One caveat: In a quick skim of the report I didn’t see enough data to tell me whether it had taken into account the fact that many of the fastest-growing cities in the South and the West were poorer to start with, and the slower-growing cities in the North and Midwest were places with higher pay (manufacturing, unions, etc.) but less economic growth, hence less population growth. In other words, does the study show causality or just correlation? If any academics or others have time to pore through the report and offer an analysis, it would be welcome.
