Civil Engineers are (unjustifiably, in my opinion, being one myself) at the bottom of the totem pole in comparison to chemical, mechanical, electrical, nuclear engineers, etc. , and salaries generally reflect that to some degree. Even when you look at our own PF Engineering Forum, you will see that Civil Engineering is not one of the sub-forums, primarily because there seems to be not much interest in that field from members.
Civil Engineers can be quite marketable without a dual degree or masters degree. Often the masters degree gets you a better starting salary doing the same work as non-masters graduates, but with sometimes more rapid advancement if you prove yourself worthy to the assigned tasks. If you want to take another 2 years of courses in another engineering discipline to go along with the CE degree, I think ME or EE would be your best bet, if so inclined, but whether or not that increases your opportunities is unknown. Civil/Electrical combo types would be most welcome to Electric Utilities, but EE courses are not easy in comparison to CE courses. Not to say that CE courses are a gut, of course.
