When asking direction to a specific address, as follows, what do the underlined parts exactly mean? Thank you very much!
Take 680 South towards San Jose. Highway #680 is a road in the northern part of the state of California in the US. One can travel on this highway north or south. The directions are to drive south on this highway. San Jose is mentioned because it is a major city and the signs will have that name on them. The directions are not to drive to San Jose but to drive in the direction (towards) of San Jose.
Take the 101 Exit South towards Los Angeles. This direction is not so clear as the previous one. If it was written, "Take the 101, exit south towards Los Angeles", it would mean to drive on highway #101 and then exit (leave) this highway and go in the direction (towards) Los Angeles. The way it is written, "Take the 101 Exit..." means to drive on some highway and leave that highway when you see Exit 101. The comma, or the lack of, makes a huge difference here.
Take the Bernal Road Exit...
