Comparing the 1889 map to the 1916 and later maps, I think there is a strong possibility that the original country road alignment was Nielson to Woodard road, and that the large looping curve past the Springdale Job Corps Center was actually originally constructed for the CRH. Adding to this suspicion is the fact that the original bridge at Stark Street had the same name as Nielson Road. Hopefully a deeper dive into the OHC reports will shine some light on this issue.
Of course, it is also clear that the 1889 map is lacking a lot of detail, so this is by no means a definite conclusion, but I do think it is likely.
