Tollgate in Bei-jing

This is a tollgate in Bei-jing. I do not know where it really is. Why? My sister's husband drove and I just needed to sit in back and done nothing. I do not need to know where it is. My sister's husband knew the place we wanted to go. Of course, my sister's home. See the middle blue board which was hanged on the top of rollgate. The meaning of those Chinese words there is Bei-jing. Is this tollbgate so Chinese? Specially enough?
