Streetcars
Up until 1913, streetcars were operated on Cincinnati Hill by the Tulsa Street Railway Company. The City of Tulsa decided that it was too dangerous a location to operate streetcars with the machinery the company was using at the time. The section on Cincinnati Avenue between Second and Third Streets has a slope of 6.33. In wet conditions the cars frequently slid down the hill. A sharp bend at Second Street made this particularly dangerous. A case was brought to the Corporation Commission of the State of Oklahoma by local citizens demanding that the City of Tulsa reinstate the service. This was denied.
