Two things become one, and only the traffic sign apologizes for it.

means To combine two or more things so thoroughly that they function as a single, unified thing.

from From Latin 'mergere,' meaning to dip, plunge, or sink into — like submerging something into a liquid until it disappears beneath the surface. English borrowed it in the 1600s for legal contexts, where a lesser estate or claim could 'merge' into a greater one and effectively vanish into it. The sense widened over time from legal absorption to the general idea of blending anything — companies, lanes, identities — until the seams disappear.
