007C00099N Pinnacle View Road over US-25 E Bell County Concrete tee beam 1958 This structure is located in Cumberland Gap National Park and is a curved, non-standard bridge that was designed in response to the surrounding environment.
014C00005N Lon Dowell Road over CSX Railroad Breckinridge County Steel stringer/multibeam or girder 1956 This is a uniquely designed railroad overpass that is supported by steel piers. The timber deck is typical of this bridge type.
038B00038N US-45 over IC (SOU) Railroad Fulton County Concrete continuous tee beam 1954 This bridge is an early example of the use of the continuous concrete beam, which is rarely seen in combination with a decorative railing in KY. It also spans a major railroad line on an important US highway.
039B00019N KY-1130 over Cruz Branch Creek Gallatin County Concrete culvert 1951 Unique railing, not standard
039B00020N KY-11 over Craigs Creek Gallatin County Concrete culvert 1951 Unique railing, not standard
043B00044N KY-54 over Short Creek Grayson County Concrete tee beam 1947 This is a group of three bridges constructed as part of a larger highway project. They reflect the post-war construction boom and are early examples of this trend. Very few bridges were built during WWII due to labor and material shortages.
043B00046N KY-54 over Spring Fork Grayson County Concrete tee beam 1947 This is a group of three bridges constructed as part of a larger highway project. They reflect the post-war construction boom and are early examples of this trend. Very few bridges were built during WWII due to labor and material shortages.
043B00047N KY-54 over Big Slough Grayson County Concrete tee beam 1947 This is a group of three bridges constructed as part of a larger highway project. They reflect the post-war construction boom and are early examples of this trend. Very few bridges were built during WWII due to labor and material shortages.
044B00010N US-68 over Green River Green County Concrete continuous tee beam 1951 This bridge is an early example of the use of the continuous concrete beam, which is rarely seen in combination with a decorative railing in KY. It also has deep girders. It also spans a major river on an important US highway.
054B00042N US-41 over drainage ditch Hopkins County Concrete culvert 1955 This bridge displays a railing that may be unique to KY. At 7 spans, it is also the longest box culvert structure in the state and is unusual in that other bridge types are normally more economical for spans of this length. The long, low design reflects a response to the geology and hydrography of the overflow ditch.
072B00020N KY-453 over Barkley Canal Lyon County Steel stringer/multibeam or girder 1946 This bridge was built as part of the development of Lake Barkley. It is an early example of the use of a haunched continuous welded steel plate girder, economical for long spans. Bridges of this type later exhibited structural problems due to welds and many have required replacement or major repairs.
096B00018N US-27 over CSX RR-CR 5011-Kennedy B Pendleton County Steel continuous stringer/multibeam or girder 1946 This bridge spans a major rail line on an important US highway. It is an early example of the use of the continuous steel beam in KY, though not the earliest. It also has decorative piers, something seen in many bridges built when passenger rail was common. It was also designed in 1945, the cut off year for the Program Comment.
097B00046N KY-3195 over Leatherwood Creek Perry County Concrete tee beam 1946 This is the only single lane bridge in KY with this railing type. It is a non-standard design, as most concrete highway bridges were designed to accommodate two lanes wide enough for modern vehicles. It was also designed in 1945, the cut off year for the Program Comment.
097B00082N Memorial Drive over Memorial Drive-KY-15Bus Perry Steel stringer/multibeam or girder 1950 The Hazard Relief Route was built to relieve congestion caused by 9000 cars a day that travelled on Main St. and was typical of post-war highway projects. The Memorial Dr. underpass over the bypass was built at a pre-existing curve surrounded by dense housing necessitating a superelevated, skewed design. The use of I-beams in such a configuration is unique and the design clearly responds to locational constraints. It also has a decorative, standard handrail that follows the curvature of the deck. The bridge was featured in a 1952 highway department pamphlet.
107B00005N KY-73 over W Fk Drakes Creek Simpson County Concrete tee beam 1954 Part of park
111X00002N IC-8036 N over service road Trigg County Concrete slab 1968 This is the Lake Barkley State Park Lodge entrance bridge. Edward Durell Stone, an internationally known mid-century architect, designed the Lake Barkley Lodge and this structure. Aesthetic details include patterned concrete piers and a non-standard metal railing. Stone also helped design the Verrazano Narrows bridge in NY, along with many famous buildings. This appears to be the only other example nationwide of his design applied to a bridge.
