Its main thoroughfares are West Marginal Way S. (northwest- and southeast-bound), S. Cloverdale Street (east- and westbound) and 14th Ave. S (north-and-south).

South Park was served by three mayors in its four-and-one-half years of existence as an independent town: S. J. Bevan (1902–1903), G. C. Lingenfelter (1903–1905), and A. G. Breidenstein (1906–1907).

On March 23, 1907, a second vote for annexation was 181–36 in favor and on May 3, 1907, South Park became part of the City of Seattle.

It replaced a bridge built in 1929–31 that had been listed on the National Register of Historic Places but was found to be in very poor condition by the 2000s.

This brick road—one of the few remaining in Seattle—constitutes the northernmost portion of a road that once led from South Park to Des Moines, Washington; eight blocks south of the Duwamish, today's Des Moines Memorial Drive branches off of 14th Avenue S. leading uphill into unincorporated King County, the area commonly referred to as Boulevard Park.
