There's a historic marker at that intersection: Presented to the citizens of the State of Alabama honoring our brother George Washington our first Masonic President and in commemoration of 200 years of freedom under our constitutional form of government.
Also at this intersection is the Alabama State Capitol Building, one of the few state capitols listed on the National Historic Register,the scene of social revolutions since the middle of last century.
The Capitol's portico is marked with a bronze star showing where Davis was sworn in as the first (and only) president of the Confederate States of America in 1861.
I figured Bainbridge started here because it is 000 while the other is 500, but Constance blows us away with her research. An interesting post Steve. Good clear shot of the signs.
