1931 McBee Rainbow Bridge over Holston River in Mascot, TN

(Archived Bridge Hunter; Bridge Hunter; Historic Bridges; Satellite)

The 785' (239m) long bridge has a main span of 222.5' (68m). "This bridge is among the largest rainbow arch bridges in the country. However this is not the only thing that makes it stand out; it is also extremely massive with enormous arch ribs. Among rainbow arch bridges it is also extremely rare for its skew. The bridge is a tied arch or bowstring type rainbow arch. It retains excellent historic integrity and appears to be in good condition despite heavy traffic including truck traffic. The bridge is the only rainbow arch bridge in Tennessee." [HistoricBridges]
