Every night while we’re asleep a crew is racing against the clock to repave Reagan National Airport’s main runway. It’s a nightly show as hundreds of workers and construction vehicles race to finish before the day’s first flight takes off.

Work started in April and will take two years, with a pause in the winter months. National Airport’s runway was last repaved over a decade ago and it’s near the end of its life because of wear and tear.

At many other airports, this repaving process isn’t too big of a deal. At Dulles, for instance, they could close one runway and have three others to use.

But National doesn’t have that luxury. It’s landlocked and has one main runway and one secondary runway that are suitable for large aircraft. They need them both open every day
