In 1903 the Alberta streetcar line spurred the growth of this then-suburban neighborhood. Over the next decade, as the population of Portland doubled, Alberta thrived and its business district would mirror those streetcar districts throughout the city. In the 1940s, as the automobile took over, redlining created a thriving multicultural neighborhood that would become known for art, jazz, great food, and a tight community. We'll explore this now hip neighborhood, its ice cream, coffee, art, history, and find out what makes it so special. One hour, 1.25 miles (2 km).
