At around 1960 the old road over Haukelifjell in Norway was submerged during construction of a new road and expansion of a hydroelectric power plant reservoir. Severald old brigdes can be found at the site.
Heres a quick teaser while I try to find time to edit the whole thing:
Cameras: GoPro Hero3 Black (timelapse) and Panasonic GH3 with 7-14 mm lens in Nauticam housing (12-35mm lens was used for above water scenes).
