News article about the 2016 rehabilitation for this bridge:

https://charlottenewsvt.org/2016/06/17/extensive-seguin-brid...

Looks like their are some concerns to be had about this process. They'll be increasing the weight limit for the bridge by 2 tons, which while written off by the project manager as not an "appreciable amount" (its a 40% increase), is necessitating a complete rebuild of the floor system, and replacement of the upper chord with wider ones. Also with the process they'll be removing the roof, which presents the opportunity for damage to occur (including possibly the incredibly unique elliptical lateral bracing system).

I did appreciate the fact that they got Jan Lewandoski (who did the '94 rehab and who has a solid reputation for in-kind authentic rehabilitation) to comment for the article, and I share the concerns he mentions with the project.
