This bridge is an uncommon application of a concrete T-beam, which never enjoyed as much popularity for small to medium spans as steel stringers did in the Vermont context. Originally the main bridge into town from the west along US route 5, this bridge was given extra ornamentation with light posts and a Balustrade railing, giving travelers a lovely introduction to the town.

The bridges use waned significantly after Route 5 was re-routed in 1975 when the Interstate system came through, making this bridge only used for a dozen homes on a dead-end road. Over the years the light-posts disappeared and the railing crumbled, giving the bridge its current decrepit look.

This must have been a classy bridge when built. I hate to see the old ones from this era allowed to decay.

Glad I was in the neighborhood to give this one a quick documentation. A replacement bridge is being built alongside it, with it looking to be getting close to done. Demolition of this bridge will probably follow soon after.
