| ArchivedBridgeHunter_1853 "Sixth bridge at this location, derives its name from the third bridge, a chain suspension bridge. First bridge built by Timothy Palmer for Georgetown Bridge Co., wooden covered bridge opened 1797, rotted and collapsed 1804. Rebuilt by Georgetown Bridge Co. in kind, washed away by flood after six months. Third bridge opened 1810, chain suspension span 136' long, 15' wide designed by Judge James E. Finley of Uniontown, PA, swept away by flood 1812; fourth span damaged 1815 by floods; fifth span built 1840 and also destroyed by flooding.

| Bridges Now and Then posted "Chain Bridge spanned the Potomac River in northwest Washington near Tenleytown. The crossing was heavily defended by earthworks (Fort Ethan Allen and Fort Marcy across the Potomac in Virginia and several artillery batteries on the high ground in Washington DC, including Kemble, Parrott, and Vermont." c. 1865. (Library of Congress) [A lot of comments disagree that this bridge is Tenleytown. Please access the "posted" link for corrections. I'll let you judge if the Library of Congress is wrong.] |

I imagine that a steel girder bridge of that magnitude would have been bleeding edge in 1938. Most 1930s bridges are steel trusses.
