I drove over the replacement bridge on January 16, and noticed the old bridge had recently been demolished. YouTube videos show the bridge being demolished on January 10, 2017. Antlers Bridge: 1941-2017

Just drove through here yesterday and the new bridge pilings are already up on both sides of the river. Even the new alignment of the freeway has been cut and concrete poured although it's not open to traffic yet and won't be for a while. The signs announcing the project are claiming a 2014 completion date.

Being designated "historic" does not protect a bridge and indeed dozens if not hundreds of National Register eligible bridges are demolished annually nationwide.

This bridge has a high degree of aesthetic value. I am uncertain of its National Register status. However, National Bridge Inventory inspection data suggests that only the deck of the bridge needs to be replaced, while the super and sub structures of the bridge should be rehabbed. Such a solution would save taxpayer dollars in addition to retaining an attractive bridge.

Are you kidding me? You call this bridge historic? It's just an old bridge needing to be replaced as is being done. If it were truly "historic" it wouldn't be removed when the new one is finished. Seems like people are trying anything to make news and or money.
