Consider each possible route from G to D.

For each route what is the minimum weight of the arcs on that route.

Choose the route where that minimum is as large as possible.

E.g. One possible route is GBCD, with weights 14, 8, 2. The minimum is 2.

Find a route where that minimum is as large as possible.

Edit: There appear to be two possible routes.
