The current emergence of a proposal to widen Interstate 270 and Interstate 495 has encouraged me to share my vision of what I believe is a smart alternative to highway widening. I call it “skyways, not highways.” The idea is to build up, not out. Building roads over existing highways makes more sense than widening roads to 10- or 12-lane highways for the following reasons:

(1) Money can be saved by eliminating the need for environmental studies and hearings.

(2) Money can be saved by not having to clear land: cutting down trees, buying property in order to clear it, using expensive heavy equipment.

(3) Negative environmental impacts could be greatly reduced.

Although building up rather than out has its own expenses, I believe money can still be saved based on the above.

You are neglecting the additional cost of a raised highway.


Indeed. Roads tend to be heavy. And I have seen raised highways in San Francisco and Austin taken down. People never liked them. Perhaps we should work to let people and jobs be closer together and stop this daily migration.
