Information About Bridge Contributed By Bob Dover

Phoenix, Baltimore County, Maryland. A few miles east of Interstate 83, about 20 miles north of Baltimore and 20 miles south of the Maryland/Pennsylvania state line.


Rural, amid woods, farms, and distant single-family houses on large lots.

Shawan Road/Hunt Valley exit from I-83. 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.

Carroll Branch

Current Status:
One-lane bridge, wood deck, carries traffic on Carroll Road, a narrow, winding two-lane road, at the intersection with Philpot Road.

Plaque on truss over roadway provides the date of 1879. There is also a very slight decoration using a circle design in the upper corners of the truss.

None known. However, the bridge is not currently preserved or in a park. It does support traffic, and further suburban development in the area could potentially increase traffic needs on the bridge. The bridge is documented in "Historic Bridges of Maryland" by Dixie Legler and Carol M. Highsmith.

HistoricBridges.org Discussion

The builder of this bridge is likely related to Gilbert and Smith of Gettysburg, Pennsylvania given the unusual pipe struts that this bridge shares with the John Eisenhowever Bridge, as well as the Gilbert name. Nelson refers to Thomas M. Nelson who later formed the more prolific company Nelson and Buchannan (and also acted as agents for Pittsburgh Bridge Company).

Its 1879 construction date makes it a very old example of a pin-connected Pratt truss.
