Small Structures on Maryland's Roadways, Historic Context Report
The "Small Structures on Maryland's Roadways, Historic Context Report" contains an historical overview of the development of Maryland's roadway system, focusing on small roadway structures less than twenty feet/ 20-feet long; a discussion of the types of small structures found on Maryland's roadways; and guidance for assessing the state's small structures for eligibility for inclusion in the National Register.
These structures may resemble a bridge, but are less than twenty feet long. There are two periods of significance for small highway structures. First, the early nineteenth century is associated with early turnpikes and the National Road.
Second, the period from 1912 to 1933 is associated with the Maryland State Roads Commission's development of "Standard Plans" which allowed easy construction of concrete structures over almost any body of water in the state.
The state stopped using the standard plans in 1933, which concludes the period of significance for many twentieth century small structures.
