Old Harford Road, one of the oldest rights-of-way in central Maryland, is a southwest-northeast thoroughfare bisecting the Parkville, Maryland area of Baltimore County. The road is a continuation of Old Harford Road in Baltimore City, and extends from the northern city limits of Baltimore to near the Big Gunpowder Falls north of Cub Hill. Old Harford Road, like Joppa Road, likely began as an Indian trail that later was adopted by early settlers to convey farm products to the port of Baltimore.
Putty Hill Avenue begins one block prior to Goucher Boulevard, and continues for approximately 4¼ miles up until Walther Boulevard. At this point, going straight would bring the motorist onto Rossville Boulevard. But a left onto Walther, followed by the next right, would bring the motorist to an older section of Putty Hill Avenue, which continues a few blocks parallel to Rossville, and after Belair Road, changes into Ridge Road. It has been written that the area known as "Putty Hill" (i.e., that area surrounding the intersection of Belair Road (U.S. Route 1) and Putty Hill Avenue) took its name from the consistency assumed by road surfaces in the area during rain storms.
