[Note the powerline towers. HistoricBridges explains: "One additional overlooked detail to note about this bridge is it had unusual riveted towers on top of the truss which held electrical wires. This was an unusual feature, and since the towers appeared to be riveted and original, they were a significant and unique historic detail."]

"The Glasgow Bridge was five-span through truss bridge over the Missouri River on Route 240...It was built in 1925 and rehabilitated in 1986. Its main span was 343.7 feet [104.8m] and its total length was 2,243.5 feet [683.8m]. It had a deck width of 20.3 feet [6.2m] and vertical clearance of 14.8 feet [4.5m]. It was narrowed to a single lane in its final few years (with stoplights on either side) before being closed and replaced in 2008-09. The new bridge reopened in September 2009 and the project was completed in autumn of that year."

"Thu, 24 Sep 2009 11:27:16 GMT — The Missouri Department of Transportation has re-opened the Missouri River Bridge at Glasgow. The bridge has been closed since August of last year [over a year] for structural repairs. That forced commuters either to take a ferry across the river, or drive hundreds of miles out of their way to get to the other side."

MoDOT did an economic impact of the closure. The traffic volume was 1,198 vehicles per day. [MoDOT]

Only the superstructure was replaced. The original piers were reused. Reusing the piers would explain why this $14m project closed the bridge for over a year.
"The main river span is a three-span continuous parallel flange steel plate three girder superstructure system. The approach spans were also steel plate girders."

[I wonder how long it took to clear the navigation channel.]
The girders were 9'2" (2.8m) tall.

MoDOT did document the bridge before they blew it up.

A good view of a high-voltage power line tower. Note that a lower voltage power line was cantilevered from the side. The railroad bridge on the right is still standing.
