MIDDLEBURY — The rail tunnel construction project in downtown Middlebury this summer spawned a burst of design creativity from Addison County architects and builders in the “Bridge 20/20” outdoor architecture exhibit. Organized by Town Hall Theater as a fundraiser, five firms designed and built large models of whimsical bridges that were constructed and erected around the larger construction project.
The Addison Independent featured photos and a story about four of the bridges earlier in the summer, before the fifth “bridge” was built. Pictured here is that fifth construction: “Terra Caelum,” designed and built by TruexCullins on the town green next to the Episcopal church across from the post office.
Also referred to as the “Earth/Sky Bridge,” this construction is a maze-like structure.
On its Facebook page TruexCullins described its design inspiration thus:
“The obelisk is an ancient form that symbolically connects the earth to the sky. This structure explodes and deconstructs the facets of the traditional monolithic obelisk, creating an interior space. Once at the center of the space, all that can be seen is the earth below and a patch of sky above … the walls creating a bridge between.”
The other bridge models in the architecture exhibit include two in the Marble Works Riverside Park, one created by Goosewing Timberworks and Smith & McClain and the other by Vermont Integrated Architecture and Nop’s Metal Works; one next to the Stone Mill Building in Frog Hollow created by Silver Maple Construction; and one made by Salamander Construction and sited in Storrs Park near Twilight Hall.
Like earlier THT public art projects, the five bridges are being auctioned for people to have delivered to their home after the exhibit ends on Oct. 16 — proceeds will benefit the theater. 
The auction is going on now. Each bridge has a sign with a number to text. The “Better United” website, accessible by texting the number on the signs, features each sculpture and its bidding activity. Winning bidders will be determined this month.
