It didn’t take long. Just weeks after Amazon’s announcement that my work neighborhood, Crystal City (aka National Landing), would be its new HQ2, the demolition — and the detours — began.

First, my cut-through was cordoned off, which made my walk from Metro to office less diagonal and hence longer. Then one whole stretch of sidewalk was blocked, a pedestrian walk constructed in the bike lanes, and the whole lot of it painted white.

Now I wait at the light and cross to the other side of Crystal Drive so that I’m strolling on a pavement-stone sidewalk that runs alongside apartment buildings where a few brave pansies still show their yellows and purples.

This is not just a construction zone; it is the construction zone. A transformation that will continue for years, and will, I imagine, outlast my presence in these environs.

There’s a tinge of excitement in it, I’ll admit. It’s not unlike the neighborhood I grew up in, full of two- and three-bedroom bungalows being built as quickly as the hammers and saws could make them. The sound of construction, the sound of new life.
