Creating proximity surfaces for path(s) in time interval 2 and adding these together yield the shortest path(s) through time interval 2.

The shortest path is delineated by the cells with the lowest value(s). The value is the actual cost of using this path. Using the Legend function this path can be derived by changing the color of the cells with the lowest value until a continuous path from origin to detination can be seen.
Here, path 4 is the sought path.
The total cost for the path is 170 + 85 = 235. (Cutoff in time interval 1 plus the cell valuefor the path in time interval 2)
