That’s what the headline of this Post piece about a study in support of widening of the Beltway—-with a $5.8 billion price tag—-should have said.

Instead, reporter Ashley Halsey III doesn’t tell us until the third paragraph that this seemingly-objective non-profit is backed by the construction industry, which if you ask me makes any study in favor of spending on its priorities pretty suspect.

Here’s the gist:

In a report released Wednesday, TRIP (or The Road Information Program) says Maryland’s recovery from the recession and its future economic viability depend on investment in relieving congestion and improving mobility.

Maryland’s transportation system has significant deficiencies that could prevent the state from reaching its full economic potential,” the report says. “Maryland’s economy and quality of life could be adversely affected if its transportation system cannot provide for the efficient movement of goods and people.”

The cost of the top 10 projects TRIP listed amount to almost $13.7 billion.

Of course we need to invest in transportation infrastructure. But you know what’s a lot cheaper, more effective, and better for the environment than building new roads? Putting housing and jobs in places that are already served by them, and improving transit to take people out of individual cars. It would’ve been nice if the Post had seen fit to balance the views of an industry group with somebody who could look at the region’s transportation issues a little more objectively.
