OSRM has supported 64-bit ids since last November:
That said, for memory-intensive applications such as OSRM, the switch to
64-bit ids can imply a massive increase in memory consumption. When working
with extracts (either thematic or geographic), it may prove wiser to filter
the data first; renumber ids into a 32-bit space, using osmium-renumber or
similar; and then run a 32-bit version of the software.
