What are the colleges i get for civil engineering for my rank 70000

Your rank is bit high. I would recommend you to take admission only in some top institute and if you dont get admission in any top institute then it is suggested you to check for other better options such as Delhi University, Lovely Professional University, BITS, Pune University.

With this rank you can hope of these kind of colleges, please check the link below https://www.shiksha.com/jee-mains-college-predictor But you can try for admission in some good private universities to get a branch of your choice. Good luck.
