31 – 33 Washington Ave. 21-70
Washington Ave. was constructed in 1889 and named on the Centennial of George Washington’s visit to Andover in 1789. Constructed over farm land of Charles O. Cummings, house lots were then sold off to residents and developers. By 1906 eighteen new homes had been built. Interesting to note that five new owners, Tyler, Lewis, Gray, Stiles and Caldwell were House Carpenters and Cummings and Wardwell were developers at each end of the avenue.
Aug. 30, 1889 Andover Townsman p. 4 - The new street, Washington Ave. is progressing rapidly, and from all appearances it is likely to be a good piece of road. The ledge at the Elm Street end had been blasted sufficiently, and the men are now engaged cutting down the ground above the grad and filling in the lower places. Quite a piece stretching from Summer Street is ready for the finishing touches.
October 25, 1889 AT – The new street Washington Ave. is beginning to look like a very good piece of road. The top dressing of red spring gravel is being put on.
