Hello everyone.

I have to describe is the Severn Bridge, a suspension bridge spanning the River Severn and River Wye in England.
I have found almost all the measurements, except for one: the sag span. I could only find the sag ratio (1/12) but I need to convert this ratio to meters. Can anyone help me with this?

Thank you very much

Then you'll need to find the span distance in meters and apply the sag/span ratio. The main span distance is listed as 3240 feet.
