030 - Seven Bridges

Serendipity 1's hit TV show Seven Bridges follows the romantic misadventures of a group of attractive singles living in the fictional community of Seven Bridges. The community sprawls across both banks of the Gellis River and also includes two islands in the centre of the river. The riverbanks and islands are connected by a series of bridges, as shown in the attached image.

Famously, the show claims that it is impossible to cross all seven bridges in one voyage without retracing your steps or crossing the same bridge twice, regardless of where you start or finish - a metaphor for life's missed opportunities.

Last year a proposed spin-off, Thirty-Nine Bridges, set on an archipelago of islands, was briefly mooted before being nixed during development.

Is Seven Bridges correct? Is it impossible to cross all seven bridges, as shown in the attached image, without crossing a bridge twice?

And what about the proposed layout of Thirty-Nine Bridges? Is it possible to cross all thirty-nine bridges without crossing a bridge twice?

NOTE: It is not permissible to partly cross bridges - any crossing of a bridge must begin at one end and finish at the opposite end.
