Terrible news. We have been to Tempe many times over the years, as one of our daughters and her husband attended ASU. We stayed at the Courtyard, which is only a couple of blocks from the bridge, and I took my morning runs in that area. Sad that at least one of the spans of the bridge has been lost and I hope that the lake has not been polluted. The only good news is that it appears no lives were lost. I would imagine that it will take quite a bit of time to do the necessary repairs and reopen the line.
