M Street Bridge (Washington, D.C.)

[2] It was replaced by a heavy wooden drawbridge in 1800, as Rock Creek was wide and deep enough that sailing ships needed to transit the bridge at that time.

The United States Commission of Fine Arts (CFA), the agency tasked with reviewing architectural projects in the capital, under Charles Moore opposed the design because it did not conform with the other park bridges, which were designed to harmonize with their surroundings.

The designers attempted to compromise by encasing the bridge in concrete and adding ornamentation.

"[2] Moore also objected that adding ornamentation would not satisfy the bridge's fundamental design principles perceived as lacking.

This situation led to the passage of the Shipstead-Luce Act in 1930, which gave the commission legal authority to enforce their decisions.
