What professional qualification certificates do road and bridge engineering and technology majors need to take?

I also graduated from road and bridge technology, and I have been working for three years now, so I can say that I am most qualified to answer your questions. It depends on whether you graduated from school or not. If the school does not recommend textual research now, it is useless to take the exam. I also graduated from the road and bridge major, and it is useless to take an advanced certificate at school. If you have time, learn more about word, excel and cad, and learn professional courses well. Don't think that college courses are useless, but you will know that college courses are still useful in the future. If you have graduated now, the construction company can take the second-class constructor for two years and the first-class constructor for four years, and the first-class constructor can be the project manager of large-scale projects. If you are interested, you can also take an examination of safety engineers, quality inspection engineers, test and detection engineers and so on. Design institutes can test architects and structural engineers in the future, and the supervision must be a supervision engineer. Typing is not easy, I hope everyone can choose a satisfactory answer.
