Just solder alone over a broken trace is not sturdy or stable. Follow Bob’s
suggestion and lay a piece of bare wire over the break and solder it on.

Is there any advantage to attempting to fix the traces over using a
jumper?
Don't use only solder to bridge the traces across the crack.
Scrape off the solder mask on either side for maybe 1/4" or more
and lay a piece of resistor lead or something similar across the
crack then solder to the trace on both sides. In really severe cases,
you could glue something flat like a piece of some old pc board
to this one to span the crack in-between where the traces are to make
it stronger. In most cases just fixing the traces is enough.
