They redid the deck of the bridge behind our house.
The highway was closed for about 2 months and it looked like a pretty extensive rework of the decking and surface.
Traffic on our road, the best alternative to the highway, went up dramatically until there was an accident on our road, then they changed the constructions signs to make it appear that both our road and the highway were closed.
I went outside one night and noticed it was extremely quiet outside. It took me a few minutes to realize that the silence was a complete lack of traffic.
Now the bridge is over and everything is back to normal, but it was strange how nice "abnormal" was.
