Seeking the Next Interstate System, This Time Without Asphalt

The construction of the interstate highway system defined the
landscape of late-20th-century America. What will be the transformative
infrastructure of the 21st century?

As Noah Kazis wrote on Streetsblog NYC
a couple of days ago, the American Association of State Highway and
Transportation Officials (AASHTO) would like to think that it will be —
the interstate highway system.

But people who don’t pour asphalt for a living have some other ideas. Portland Transport pointed us to a post on Richard Florida’s blog
in which he listed some ideas his readers had on the subject of
change-making infrastructure for the future. They included high-speed
rail, a universal broadband network, and denser, more walkable
communities.

All of which sound pretty good. But it remains to be seen if any of
those solutions have the kind of political muscle behind them that the
highway lobby has enjoyed for the last half-century.

What do you think the defining infrastructure project of the 21st
century will be, or should be? Are such grand projects even possible in
the current economic and political climate?
