photo of road being constructed from two ends that do not meet. 
Either railroad or asphalt road.  Seeing teams from two section
looking at each other in bewilderness.

Maybe this will help?

I couldn't find the one I was looking for that I seem to remember
being entitled "End of the Line". Maybe someone else can find it.

I found a mention of this old cartoon:

"cartoon: misaligned railroad tracks, workers arguing]
This cartoon is from? Frank adams, new cartoon book   "THEN YA JUST UNTWIST" 

Frank Adams lives in our desert, you see, we have some Mountains that
shoot up from the floor of the desert, Frank and his family live on
one of these ship-like mountains. SOme say, he sits with his back
against a pine tree and looks down on us desert folds through a giant
telescope getting fun from our screwball activity, like in this
cartoon.

I've been unable to locate this cartoon or book, so far.

Another cartoon mentioned:

"It's epitomized by another great cartoon?as life's trials often are.
This one shows rail workers from the East and West coming together to
link the tracks, except that they're misaligned a few inches at the
point where they're supposed to join. Someone wasn't paying
attention."

I'm hoping these descriptions may help others in locating the cartoon.
 Finding a photo is proving almost impossible.
