The new road is great. I take it a few times every month. The route I take is 330 miles from Solana Beach to Penasco crossing at the east crossing in Mexicali. It is 440 miles from Penasco to San Diego crossing in Sonoyta. Very easy drive, just a few things to watch for...as you come into San Luis there are 2 Pemex stations, across from each other, you make a left on the dirt road directly past the Pemex on your left then make another left onto the pavement which takes you a T in the road where you make a right. Then in about 2 minutes you will come to a stop where you make a left onto highway 2, the toll booth is then just ahead (12 pesos). From this point you are about 45 minutes to the east crossing in Mexicali. Heading towards Mexicali you will exit at the sign for the airport and then follow the directions to the airport as you get closer you will be able to see the control tower at the airport. At the airport stop sign you will make a left go about 10 miles and as you come into Mexicali there will be an intersection with a traffic light and a Circle K. Make a right at that intersection and then simply follow that road which will take you directly to the Mexicali/Calexico East crossing in about 5 minutes. There is a Sentri lane, Ready lane and about 10 or so regular lanes to cross. When you cross the border you will just follow the road to Interstate 8. It may sound a bit confusing but it is actual a very direct route. If you zoom in on the link in Google maps and follow the route you will clearly see the directions.
