Closed for months? Only because government is going to “fix” it.
Atlanta. 2017. Interstate 85 bridge collapse.
https://en.wikipedia.org/wiki/Interstate_85_bridge_collapse
Homeless jerks with a campfire ignited many, many spools of fiber optic conduit stored under an elevated section of I-85 a little north of Midtown Atlanta, between the I-75 split and GA 400. Destroyed a section of the elevated highway, some of the supports.
Government got a contractor on board to replace who had huge incentives for a fast replacement, then got out of the way other than ensuring quality of construction. 43 days after the event, I-85 reopened.
