Checked Vdot tonight and it states replacement and to be complete June 2021. Sad really would think rehabilitation of such a small and low bridge would be easy and cheaper than a replacement

Let's hope they do the same fantastic job as they did on the Stones Keep Bridge! (Last 4 pics)

Signs up stating June 29 2020 bridge will be closed.

barricades are at the end of the road but have yet to be placed to block the road this week. Do no know if this is a bridge replacement or repair/restoration like the nearby bridge in Elliston-Lafayette. I shall keep an eye on what is going on with this bridge

I would call them outriggers.

Is the bracing here note worthy, I do not believe I have seen this before. Is it acting as an outrigger or a vertical? Or both?
