If you look closely at the White River Junction overhead BGS that PennDOT Fan posted, you should quickly pick up on three of my pet BGS peeves:
1) Cardinal Direction to left of Interstate shield (North 89). This treatment is normally reserved for exit direction signs where the advance signs are left arrow diagrammatic signs, and is intended to give the driver a consistent legend format throughout the entire sign series for the interchange. On an exit direction sign where the advance signs are normal BGS format, this distinction is NOT needed. None of the new advance signs for I-89 installed by NH Bureau of Turnpikes in 2007 (?) are diagrammatic signs, and this exit isn't a left side exit either.
2) Exit Only plate with standard white up arrow to the right. Should be full black on yellow Exit Only banner with black downward arrow over right lane.
3) No exit numbers at Interstate highway to Interstate highway connections. New Hampshire continues to be notorious for this practice, even on newer sign installations such as I-93 to I-89 in Bow and on I-93 to I-293 in Manchester. What's even worse in the case of the diagrammatic signs for I-293, NHDOT placed an "exit tab" on these signs that reads Manchester Airport.
BTW, the northbound advance sign sequences on I-93 for both I-293 and I-89 also highlight another of my pet peeves (which, again, New Hampshire is notorious for). Advance BGS panels (usually at the 2 mile point) on Interstate mainlines that only indicate "Junction" and the route shield, with NO destinations provided.
