US 70 Mountain Fork River, McCurtain County

Built in 1948 by Oklahoma Paving Co., this 5-span structure carries US 70 across the Mountain Fork River in style! Above, in this through shot, you can quite clearly see all five spans: three 100-foot long Parker pony trusses, and two 210-foot long, 10-panel Parker-K truss through trusses. All spans are of steel with riveted connections and concrete decks. These decks are 28 feet wide and feature wide curbs.

Below, a close view of the trough spans. As you can see, the portal bracing has been greatly altered, as evidenced by the cut angles and plates. However, the modification appears to have gained nearly 2 feet of clearance, enough to have kept this bridge standing. Note the double lacing on the upper chords and endposts.

Below, close  of the west through span. It looks like the abutment is resting on rock.


Above, looking west with the pony spans again in the foreground, This bridge is in overall good shape, and is not loadposted.
