I believe I saw this referenced earlier in this thread in getting the streetcar to Price Hill, but why not run a short tunnel under the location of the old incline? Less than a half mile tunnel could start at W. 8th/State and emerge at W. 8th/Grand then either continue running up W. 8th to Elberon or turn and head up Grand to Warsaw. This could make for an easier entry into the neighborhood than either Warsaw or Glenway and access all that residential in the Incline District. It would be similar to the Sunset Tunnel in San Francisco.
