What James Kelly describes is a good repair for premium instruments. Do this repair if you want.
I would not try to close the crack. The soundboard below is also separating and will probably open the joint again as it spreads.
There is only one pin on the speaking side that will be affected and on this piano it will not be of any consequence, therefore I would
fill the gap with epoxy. Tape off either side of the bridge to dam the flow of epoxy. Fill the crack, let it harden and re-notch the bridge
at the notches effected by epoxy. I also see another couple of cracks the use filling. For the big crack, use medium viscosity epoxy
and use low viscosity epoxy for the smaller cracks in other places to prevent the same problem from happening there.
Good luck.

Subject: Cracked bridge
A customer of mine has a number of pianos, including one very old player piano that he likes to tinker with. He knows it's a better candidate for a sledge hammer than a tuning hammer, but he has fun with it. There is a nasty crack in the lower portion of the long bridge (see below). Any suggestions on a somewhat crude method to pull it back together? Filling with glue/epoxy and clamping? I'd appreciate your thoughts about methods and adhesives with the knowledge that this piano will never be close to a refined instrument.
Thanks!
