If you've ever wondered why Moraga Avenue is named that, this article helps explain it. Moraga Avenue becomes Thornhill Road, which originally continued uphill through Sobrante Road over the top, then down hill through what's now Huckleberry Botanical Preserve. Did you know there was a Shepherd Canyon tunnel and a Pinehurst Freeway planned? A land 'war' in Redwood Canyon in the 1870s? #history #mccosker #ContraCostaCounty #AlamedaCounty
