A reader sent a link to this site and I thought it would be of interest to all of you. This site, produced by the National Park Service (NPS), has detailed maps showing the routing of various national historic trails. Of interest to California, it shows the National Old Trails Highway (US 66), El Camino Real (US 101 for the most part), Old Spanish Trail, and a few others. Come check it out!

San Diego’s Mission Valley has changed quite a bit over the last century. It has gone from farms to condos. Dairys to grocery stores. Dirt roads to major freeways. In 1947, the first iteration of the current State 163 / I-8 interchange was completed as shown here. Left on and offramps were the order of the day. Challenge Dairy’s San Diego headquarters can be seen in the upper left corner of the interchange. Additional changes to the junction took place in 1959, 1978, and 1991. All of these bridges have been replaced but their legacy remains today with the outer ramps on either side of the 8.
