What will the United States be like in 20 years when today’s toddlers are in college or trying to land that first job or maybe thinking about starting a family?

The answer will depend to a great extent on decisions we make now about the American infrastructure.

This came to mind as I was reading about yet another closure of the problem-plagued San Francisco-Oakland Bay Bridge, which is more than 70 years old. In 20 years, will today’s toddlers be traveling on bridges and roads that are in even worse shape than today’s? Will they endure mammoth traffic jams that start earlier and end later? Will their water supplies be clean and safe? Will the promise of clean energy visionaries be realized, or will we still be fouling the environment with carbon filth to the benefit of traditional energy conglomerates and foreign regimes that in many cases wish us anything but good?

The answers to these and many other related questions will depend to a great extent on decisions we make now (even in the midst of very tough economic times) about the American infrastructure. We’re trundling along in the infrastructure equivalent of a jalopy, with bridges rotting and falling down, while other nations, our competitors in the global economy, are building efficient, high-speed, high-performance infrastructure platforms to power their 21st-century economies.
