Properly signing Cloverleaf ramps

[shadyjay]

So driving around today got me thinking of the different ways that cloverleafs are signed.  Personally, I think Massachusetts does it the best...

Exit # A-B
    Route
Town Listed 1
Town listed 2
   1  MILE

  EXIT #A
  Route  Dir.
Town Listed 1
   1/2 MILE

EXIT #B                   EXIT #A
Route  Dir.                Route   Dir.
Town Listed 2          Town Listed 1
   1/4 MILE                     ->

  EXIT #B
Route   Dir.
Town Listed 2
      ->

Connecticut is all over the place, sometimes with two separate initial signs (such as I-91 North Exit 47, Exit #B 1 1/4 Mile / Exit #A 1 Mile) and sometimes giving no advance notice that there are two separate ramps, until the first ramp separates (I-395 NB Exit 13).  Exit 39A-B on the 'turnpike has them combined on the 1 and 1/2 mile, but gives notice of two separate exits with a EXIT 39A only 1/4 mile sign. 

So is there a MUTCD preferred way to sign these types of interchanges?  How does your state sign cloverleafs?  And, should there be a uniform way to sign cloverleaf ramps?
