Boomin Bridges

I just heard the Westwood bridge get blown up. I live about 15 or so miles away from it, so I thought it was maybe thunder, but looked outside and it was clear as a bell. Then maybe I thought it was a sonic boom. The boyf called and asked me if I heard the boom way out here and I said yes, and he said it was the bridge being demolished. (He was working in town so I imagine it was WAYYY louder out there!)
It is being torn down to make way for a new one. It was an old large bridge and has been there for a long time. These photos were taken last year.
