I'm quite puzzled.
Most vines have heart-shaped leaves (e.g., smilax, bryony), palmate leaves (e.g., hedera), or odd-pinnate leaves (e.g., wisteria, jasmine). AND, most vine leaves alternate along the stem.
In contrast, these are elliptical and opposite. I know most of the common vines on sight, but I don't recognize this one. When I am able (at my other computer), I will look through my database and see if I have a vine with those characteristics.
I don't suppose it could be mock orange (Philadelphus) with unusually large leaves. It doesn't seem likely. Mock orange leaves are closer together and serrated and usually a darker shade of green. Maybe one of the elliptically leaved Loniceras, but I don't think they grow that big. Asian bittersweet can grow quite large and likes to twine, but the leaves are serrated.
Marsdenia leaves look somewhat like this but it's a tropical plant.
