ADDITIONAL INFO:
During years surrounding 1900, Allegheny County, under the direction of County Engineer Charles Davis, was busy throughout the county building stone arch bridges of a simple and similar design. This bridge exhibits the more common design features of the County's stone bridges. The design and construction details match many others still standing elsewhere in the county.

The 1876 Hopkins "Atlas of Allegheny County" shows Jno. McIntyre's home just to the north of the intersection of McIntryre Rd and Allison Rd.

The 1876 map also shows McIntyre Rd and Turner Rd as a more or less continuous road, but the present course of Gibsonia Rd in place only to the west. All traffic crossed the McIntyre stone bridge. Travel to the east was by way of an older road, Reichenbach Rd, roughly along the path of the recently-built Havencrest Rd. Reichenbach Rd (also spelled Reichenbaugh on the 1876 map) recrossed the West Branch of Deer Creek to meet Middle Rd to the east of Deer Creek.

Other nearby bridges on the newer section of Gibsonia Rd were constructed in 1960.
