Which transportation projects are the smartest investments, and which are the most ridiculous boondoggles? The Sierra Club has put together a solid list in a new report titled “Smart Choices, Less Traffic: The 50 Best and Worst Transportation Projects in the United States.”
The Sierra Club evaluated each project based on five criteria, including its effects on oil use, the environment, public health, land use, and the economy. A glance through the list quickly reveals both who is innovating for the future and who is wasting staggering sums on backwards projects, with most of the good ones originating from local governments and transit agencies, and the worst coming from state DOTs.
“Old highway spending habits die hard,” write report authors Rachel Butler, Ann Mesnikoff and Megan McLean. “U.S. transportation policy is largely getting it wrong.”
The list of “worst” projects is dominated by 1950s-style mega-highways and road expansions, the cost of which frequently reaches into the billions. Among the lowlights is Dallas’s Trinity Freeway, which costs an astounding $222 million per mile. Also notable is Phoenix’s proposed $2 billion South Mountain Freeway, a pricey eight-mile sprawl generator, which, the Sierra Club reports, hasn’t gotten past the planning stages due to lack of public support. Another worthy “worst” is the Interstate 5 widening in north San Diego County, which would widen the road to 12 lanes for the go-for-broke price of $4.5 billion.
Seattle’s Alaskan Way Viaduct — a Big Dig-style buried highway — is also singled out in the Sierra Club’s Hall of Shame. This project, which won out over the idea of replacing a damaged elevated highway with an at-grade boulevard, barely runs two miles but is expected to cost more than $3 billion. Another national embarrassment is I-269 in Memphis — the city’s second outerbelt — which the Sierra Club describes as “mainly a real estate development scheme.” Florida’s proposed 150-mile Heartland Expressway, through some of the state’s last undeveloped natural environments, wins mention as well — not only because FDOT has come out and said it can’t afford the $5.6 billion pricetag, but because it is ethically suspect as well. One of the central advocates is a state senator who, as a major land owner on the corridor, also stands to reap a windfall from its completion.
