Harry B. Edwards should get a lot of credit for building the following six cast and wrought iron, bowstring arch truss bridges in Indian Territory along the Beale Wagon Road during a six-month period beginning in the latter half of 1859.

Beale's Trusted Friend Harry B. Edwards
I have wondered how E. F. Beale got the six iron bridges noted above built so quickly for his Beale Wagon Road to the Pacific. The six bridges were located along a 180-mile stretch of his survey while passing thru Indian Territory (IT) in early November 1858 as Beale was working his way all the way back to California by 1859. The bridges were prefabricated in Philadelphia during middle 1859, disassembled, shipped by steamboat to Fort Smith, all installed back along the Beale Wagon Road in IT by late 1859 (except for Poteau, but it got done as soon as the local politics could be resolved). There was no telegraph connection yet to the West. So “How did Beale get it done?”
The answer seems to be that Beale recognized that he would need to solve this “hurry up” problem, and chose his trusted friend Harry B. Edwards of Chester, Pennsylvania for such a daunting task. Edwards must have had the construction and iron work experience (back in Pennsylvania) necessary to successfully accomplish the task, because he did.
Beale got Edwards to join his survey and construction team in Fort Smith in late October 1858. Then Edwards worked with Beale on siting and sizing up each iron bridge as they worked their way west in IT in early November. Edwards was still with him on November 5 when Beale decided to build (as it turned out) his last iron bridge, the one across Little River at Edwards Trading Post (Aird’s Place). As Beale moved on further west along the ridge line between the Canadian and Little Rivers, he recognized the land was becoming drier and that only the re-crossing of the Canadian lay ahead (from Marcy and Whipple’s surveys) which might need an iron bridge. He sent a scouting (pioneer) party ahead to find the best Canadian crossing site--near Slaughterville. Beale soon decided not to bridge it, so he considered the site-selection for iron bridges done. On November 15, 1858, Beale ordered Edwards to return back east and superintend the design, fabrication and construction of the six iron bridges that had been selected, as noted above. The next day, November 16, Mr. Edwards headed back from Beale’s camp near Slaughterville (near Choteau’s Old Trading Post) to begin his Iron Bridge building—a job well done.
