Case contract

Uppercase, delete periods, split. Two-token phrases RURAL ROUTE / RURAL RTE -> RR and HIGHWAY CONTRACT -> HC are matched before single tokens RR, HIGHWAY/HWY -> HWY, HC, BOX/BX -> BOX. A fused token "RR" + digits splits into RR and the digits. Other tokens pass through; join with spaces.

Why this case matters

Rural delivery lines have no street name; their route and box tokens are the whole delivery address and must normalize identically.
