1891 Map of Washington’s Street Lamps Tom GoDCers Love Maps Thu Aug 22nd, 2013 1 Comment This is an interesting and unique map … probably not one you’ve seen before. It shows all the underground cables, mapped in 1891. At the time there were only 321 electric lamps, mostly along major thoroughfares, with close to 5,000 gas lamps. 1891 map of street lamps Source: Library of Congress Amazon.com Widgets email Tags 1890s, street lamps ET No street lamps near my house. Not surprising really. What was interesting are all the street lamps on E leading up to the cemetery which is pretty much in line with the fact that one of the first streets on the Hill to be paved was E because it led to the cemetery and paving held up better with all the carriage traffic and heavy caissons.
