The commute from Escondido to San Diego is not easy right now at rush hour, but in a year or two, it will be much better.
Currently there are two reversible car pool lanes from Highway 56 to 163 in Miramar, but there are going to be four car pool lanes from Escondido to 56 by the end of the year, and Caltrans is going to make it four lanes from 56 to 163 also. There will be 3 lanes going south in the AM, and one lane going north, and for the afternoon rush hour, the lanes will be reversed.
Single riders will be able to purchase Fastrak so they can get in the car pool lanes also. When the four additional lanes are completed from Escondido to 163, the commute should be very easy.
