Here's what I posted on ATC's trail updates page. This comes from a combination of sources.
The Iron Bridge (mile 1492.2 from Springer) over the Housatonic River north of Falls Village is officially closed to pedestrian traffic at least until mid-November. A temporary roadwalk will bypass Falls Village on the west side of the Housatonic River.
Hikers should follow the signs along the road. Northbound directions: at the junction of Rts. 112 & 7, follow Rt. 112/Lime Rock Road west 0.9; turn right (north) on Dugway Road and follow it 2.2 miles north to where it ends at Falls Mountain Road and rejoins the white-blaze route at the west end of the closed iron bridge. This route is 0.5 longer than the 2.6-mile white-blazed route and bypasses all the services in Falls Village.
If you go into Falls Village you will have to retrace your steps back to Rt. 112 to pick up the A.T. again, as there is no way back to the west side of the Housatonic once the A.T. crosses to the east north of Rt. 112.
I'm somewhat familiar with this area since I section-hiked the same relo when the bridge on the south end of town was closed to hikers a few years ago in the fall. (I've inserted a photo that shows the start of the relo at the south end).

It's a very pretty roadwalk--I've attached a few photos below. I also day-hiked parts and scouted it out by car when I was driving back from another section-hike in New Hampshire last summer, but if anyone more knowledgable about the area has any suggested edits, please post them here, and I'll update ATC's page as well.
