What would we do without bridges?

I've got a 'thing' about bridges at the moment! Maybe it's triggered by the photo for this month on the calendar I make each year from my own photos:

Lake Tekapo

But I think bridges are even more in my awareness because of the number of bridges I walk or drive over almost every day. The following photos were taken over the last couple of days on walks no longer than half an hour from home .

Without these bridges my life would be much more limited. Some places would be hard to get to; some of my walks would be curtailed; some beautiful locations could only be seen from "the other side of the river" ...

So I've been thinking, how might I be a bridge? Or perhaps sometimes I am without even knowing it. Maybe you are too. For example: A bridge between two sides of an argument, a bridge to connect two people who  haven't met, a bridge from one point of view to a broader perspective, a bridge that will hold someone as they cross an emotional chasm, a bridge to make a long journey shorter and easier...

I appreciate people who have been 'bridges' for me over the years and I hope that I have been, and will continue to be, a bridge for others.
