Information About Bridge Contributed By Bob Dover

Near Fallston, on the border between Baltimore County and Harford County, Maryland. A few miles north of Interstate 95, about 15 miles northeast of Baltimore.


Rural, in woods inside Gunpowder Falls State Park.

Joppatowne/Mountain Road exit from I-95. No parking available, but traffic is very light, and you can pull over on a shoulder and get to the bridge without too much trouble.

Little Gunpowder Falls

Current Status:
One-lane bridge, wood deck, carries traffic on Bottom Road, a narrow, winding two-lane road through the State Park, at the intersection with Guyton Road.

No decorations or date plaques on bridge.

None known. The bridge is located within a State Park, and substantial development which would increase traffic needs beyond the bridge's capability is unlikely.

HistoricBridges.org Discussion

This bridge has the roadway-facing lacing on its vertical members, something that Wrought Iron Bridge Company often used (when other companies oriented the lacing facing the portals), and it has the typical cast iron brackets upon which the now-missing portal-mounted builder plaques were once located. However the plate style portal bracing is something that is otherwise unheard of among the surviving works of this company. It is not known why it was used on this bridge. One is led to believe it is original, given the plaque mounts are attached to it.
