This bridge's main span of 700 feet makes it one of the longest simple truss spans ever constructed. The second longest simple truss span in the world when completed, it is only 20 feet shorter than the Metropolis Bridge that Modjeski had designed six years earlier. The Metropolis Bridge was the longest simple truss span in the world when built. It is also noteworthy for its association with Ralph Modjeski, one of the most famous bridge engineers in the 20th Century. The Michigan Technic reported that it this bridge cost $1,250,000:

Same as BH 60224.
There is a valid approach to preserve this important historic
bridge(REF. The Secretary of Interior's Standards with Regard to Repair, Rehabilitation, and Replacement Situations,endorsed in " FINAL REPORT A MANAGEMENT PLAN FOR HISTORIC BRIDGES IN VIRGINIA".
The approach -Rehabilitate the bridge to carry an HS 20 (36 tons) economically and as quickly as possible.
Nobody has noted how significant this bridge is so I added a statement of significance. At 700 feet its one of the longest simple truss spans around.
A bridge in Nenana... over the Tanana... makes me want a Banana... ;-P
