I drove across the bridge on Monday the 24th and I just happened to notice that the north side was locked. I didn't know that they kept it closed.
I drove across the bridge again on Monday the 1st and I saw people walking on the north side, so I had a hunch that they'd closed the south side. I wasn't paying attention on the way back so I didn't check closely. I guess my hunch was correct.
At least they didn't close it in the spring or summer.
