slip roads
Motorway entry lanes
Slip roads are the short stretches of roadway that connect a main highway to other roads—the ramps you use to enter or exit a motorway or expressway.
The term is primarily British; Americans say on-ramp and off-ramp or entrance/exit ramp.
Traffic backed up on the slip road leading to the M25.
