Deep Cut Lake Road Bridge #46
Posted March 14, 2018, by Dana and Kay Klein

County 70 A Steuben County NY has 7 bridges over Big Creek. ALSO a couple over Big Creek Road which has 2 or 3 over Big Creek and is crossed by 70A. Run directly parallel. Have cut through there and noted plethora of bridges, notable only cause of density. Have ascertained pre 1930 many of these were bowstring ponies!Added an 8 mile stretch, next time through there will look for old abutments

Question: Is anyone familiar with another area that has a stretch on bridges on one road over such a short distance? It is only .8 miles between DCL # 46 and DCL # 50. DCL # 44 is only about a mile to the east. I think this little jog should be seen by all!

Yes... Given that the shift from building stone abutments to those made from concrete happened at the turn of the century, I would say there is a very good chance that the foundations are from the railroad.

Two possible scenarios I have envisioned are:

*The road was developed ca. 1900-1910 with the through truss and the pinned pony having been built at that time. The other 2 sites may have been crossed with temporary structures until the riveted ponies were constructed about 1920.

*The road wasn't developed until about 1920(1921), with the 2 riveted spans being built then and the other 2 bridges being moved in from other locations. Given the nearby proximity of US 50, it is certainly feasible that bridges may have been available with road upgrades around that time period.

So we agree on this much. The railroad right of way was not available for the road until 1899 at the earliest. Some of these bridges may date before that but if that is true they were moved to the new road on Beaver Creek. The stone bases for the abutments were likely from the railroad bridges before 1899.

I believe the dates for these spans are all wrong...

The 2 riveted ponies are listed as 1890 which is 2 or 3 decades too early for riveted structures. The 1921 date would seem to be more appropriate. The pinned pony could date to 1921, but is likely a decade or so older. The through truss is also listed as 1890, but the use of angles for the lattice in the portal bracing is more akin to a bridge from around 1910.
