There is only one ABET-accredited online degree in Civil Engineering in the USA. It is offered by University of North Dakota. Study requires short-term trips to Grand Forks, ND, for labs and seminars.

Engineering and online degrees don’t mix. That’s not to say that such degrees aren’t available. . . but they’re generally a bad idea. Employers will also not think too much of them.

What I’ve always heard is that even people who graduate from traditional programs where there’s a lot of hands-on experimentation/trial and error still don’t know much about the real practice of engineering (just the raw knowledge) until they’ve been on the job a while to learn what they don’t teach in class. For one, the laws of physics only work right if you can fully characterize the system. . . and that’s basically impossible outside a textbook setting. If you’re never forced to wade through a bunch of knowledge to figure out what you really need when you’re staring at some physical object that’s not doing what it’s supposed to, I’d be a little concerned.
