Biiiiig concrete thang

I am on I-90E, on my way home from picking up my father at Yaddo and visiting a friend from the NHC Summer Institute. The trip there was uneventful, and I had an excellent time in Saratoga Springs. On the way back we encountered, in rapid succession, two trucks carrying gigantic concrete I-beams, probably for some sort if overpass construction. For some reason, they were traveling in the left lane, at about 50 MPH, slowing everyone down, especially because each of them was traveling in a convoy of two police cars and two maintenance vehicles. It reminded me of the scene in The Dark Night when they are transporting Dent to the prison in the police convoy. Except no one was firing a rocket launcher at the trucks. Considering the speed they were going at, it probably won’t be long, though.
