The Incline

I have been doing some research on the area and found something interesting, the Duluth Incline.   The Incline ran on 7th Ave. W. from Superior St to Skyline Dr.   It dates from about 1891-1939.  In some versions the trolley cars were large enough to hold a horse and carriage.  For some time it was the only and safest way to the top of the hill.  It was also motivated by development at the top of the hill.  There is a bar downtown that gets it name from this.
