The Tank Farm Loop near Kellyville and a 1926 truss bridge near Chelsea, both on older alignments of Route 66 in Oklahoma, were added to the National Register of Historic Places, reports the Associated Press.
Here are the details of the Tank Farm Loop.
Roadbed section beginning approximately 0.6 mile west of the I-44 overpass west of Kellyville in Creek County. Total 1.6 mile section of 1926 PC paved alignment bypassed in 1938. An excellent example of first-generation paving which crosses several different terrain features. Known by many Route 66 hobbyists as the Tank Farm Loop because it passes through a former oil field.
