  In 1960 Nash-Williams proved that an edge-connectivity of 2k is sufficient
for a finite graph to have a k-arc-connected orientation. He then conjectured
that the same is true for infinite graphs. In 2016, Thomassen, using his own
results on the auxiliary lifting graph, proved that 8k-edge-connected infinite
graphs admit a $k$-arc connected orientation. Here we improve this result for
the class of $1$-ended locally-finite graphs and show that an edge-connectivity
of 4k is enough in that case. Crucial to this improvement are results presented
in a separate paper, by the same author of this paper, on the key concept of
the lifting graph, extending results by Ok, Richter, and Thomassen.
