You're gonna take 25 South to Las Cruces. You can pick up 10 West from there.
We take the A14 to Birmingham and then pick up the M5.
I guess the take means to choose a road and start to drive on it. What exactly does the pick up mean in this context?
I've found one definition:
pick up: find and take a particular road or route. "they veered left and picked up the road which ran alongside the river"
So what's the difference between take and pick up here?
