Nonlocal transport, which goes beyond the Ohm's law, can be a key to understanding systems with topological order or edge states. Here, we report an unusual nonlocal charge transport in the nodal-line semimetal ${\mathrm{ZrTe}}_5$ that occurs in magnetic fields applied along the $a$ axis. Surprisingly, the observed decay length of the nonlocality exceeds $100\mu \mathrm{m}$ and it increases linearly with the sample width. This nonlocal transport is detected not only in the longitudinal configuration, but also in the transverse one as an unusual nonlocal Hall effect. Our findings demonstrate that the nonlocal response can offer interesting insights into topological quantum materials.
