This is the detail map for Stockton from the 1956 official California highway map. This map was on the rear side of the map along with detail maps for other California cities. US 50 no longer reaches Stockton, with the McKinley Avenue portion of the route now county highway J3. US 99 is now the California 99 freeway. California 4 is now mostly rerouted along a freeway in Stockton, and California 8 is now California 26. California 88 is the only route on this map that hasn't changed.
