This imposing Pensylvania truss bridge seems to have carried a now-abandoned interchange between the Erie RR and the B&O RR. The track running underneath it is a Norfolk Southern line running on the north side of the Mahoning River which, from historic maps, seems to have been an old Erie RR line. There is a CSX line running on the south bank of the Mahoning River which seems to have been an old B&O RR line. The abandoned section of track that included this viaduct seems to have split off from the B&O line just west of Market Street, then crossed the Mahoning River a couple of times (also on abandoned bridges) before meeting the Erie RR near a (now-abandoned) steel mill just north of Division Street.
