The beam dump lines in the main diagram are shown outwards-curved so they stay clear of other IPs and match the incoming injectors.

But they actually run straight, after the beam is kicked sideways a little and then down (see detail).

The main diagram is also a reminder that to spread the impact of the bunches on the graphite stops the beam is swept in a curve, as shown in this 25-bunch dump (note that the BTVDD images on the left are just 30m from dump, much further along the path than the BPMDs):
