Just making a note: this 1981 bridge over I-90 just west of Big Timber has a hog wire fence atop the usual jersey barrier. I've never seen hog wire on a bridge before, let alone on one on an Interstate highway.

The Billings Gazette reports that a bridge built across the Yellowstone River in 1931 along old US 10 (paralleling I-90 between Reed Point and Columbus) has been closed due to fears of imminent collapse.

--- Quote ---Montana Fish, Wildlife & Parks closed a 200-yard stretch of the Yellowstone River east of Reed Point Monday because an old highway bridge is in danger of collapsing into the water.
The Montana Department of Transportation informed FWP this week that the Twin Bridges Road bridge is close to failing.
About half of one of the bridge piers located in the main channel of the river has been scoured away, said Stephanie Brandenberger, a bridge engineer for MDT.
... The bridge was built in 1931. The concrete and rebar footings are original, so they've lasted for 90 years as the Yellowstone River battered them with debris and high water.

Yikes. :-o :-o :-o I don't like the look of the eroded concrete showing the rebar. They better figure out how to at least rebolster the structure or get a new one in place soon. Good call by MDT to shut it down before any vehicle crossed it and fell into the freezing cold Yellowstone.

I have a feeling MDT is just going to tear it down. The bridge allows access to a couple houses and ranches along a short stub of the old highway between the river and interstate. It would be easier and cheaper for MDT to work with Montana Rail Link to allow them to use the railway access road under the interstate.

Major overhaul of dangerous I-90 bridge in Yellowstone County scheduled for fall
--- Quote --- It’s called the 1-90 Yellowstone River project, and it will mean big improvements to an approximate 2.6 mile stretch of the interstate between the 27th Street exchange and the Lockwood exchange, adding a third lane in each direction.
