Heavy rains during the 1964 Christmas Flood brought water raging down Mosby Creek with the resulting force
cracking the lower chords of the bridge.
Four years later, heavy snow falling in the Willamette Valley caused the roof bracing gave way and the entire roof caved in.
Repairs to the bridge made it usable again and it carried a 20-ton limit until it was bypassed in the mid-1980s by a concrete span.
The Stewart Bridge was officially retired in 1987, with one of the approaches removed, fumigation of timbers, and installation of a
wire fence inside a portal for safety of pedestrians.
In the 1993-95 biennium, the Lane County received a grant of around $48,000 from the Oregon Covered Bridge Program to restore the bridge.
