Perhaps is this a very simple operation (then please forgive my ignorance), but I am not yet sure about how to proceed with this task. I have a vague idea about using euclidian distance for both lines combined with zonal statisics...

The attached figure illustrates the challenge. Any ideas about how to solve it will be highly appreciated.

I would be interested as well to see an experienced user bringing a sound answer. There are several tricks that I could foresee as a casual GIS user, and I will explain them if needed.

Best regards,

PS: what is the scale of your map by the way? After several interactions with ESRI, it seems to me that there is almost no way to perform geodesic computations in ArcGIS and, as there is no global equidistant projection, this is a problem for large scale distance computations. This is an open question to me indeed; I personally perform my geodesic computations with MATLAB and I would be thrilled to open another thread about this point if someone tells me that I am wrong on this PS.
