On a somewhat [un]related note,
Mapmikey just posted a link to the WVDOH Factbook:
https://gis.transportation.wv.gov/gti/Factbook/Appendix_B.pdfThe lack of information about roads and bridges in this document doesn't surprise me. On the other hand, this document shows how important the removal of tolls from bridges is to West Virginians (and probably a lot of other folks, also). However, West Virginians still remember some of their toll bridges fondly by name (even long after the tolls have been removed). Locals still call them the Winfield Toll Bridge and the Dunbar Toll Bridge (and even some still say West End Toll Bridge for the now US-52 crossing of the Ohio River). And the Lions Club in St. Marys still have a Toll Bridge Fundraiser, even though tolls on the old St. Marys Toll Bridge were removed in 1946 and the bridge was closed and dismantled after the Silver Bridge Disaster (its twin sister).
Anyhow, after the removal of tolls on the Dunbar Toll Bridge, I believe that this leaves two privately-owned toll bridges in West Virginia. This one in Newell and a smaller Oldtown Toll Bridge (technically in Maryland) crossing the Potomac River near Green Spring. We should correct the assertion from the owners of the Oldtown Toll Bridge that it is the only private toll bridge crossing a state border. That doesn't even come close to importance of the Newell Toll Bridge.
Fun geographical fact: The Newell Toll Bridge goes east to cross into Ohio. (Let me cross-post this one into the Geographic Oddities thread).
