G20 Series — End of Work Zone / Road Work Guide Signs
Guide Signs · CA MUTCD Part 6, Chapter 6F
The G20 Series marks the downstream end of a temporary traffic control zone, signaling to drivers that normal roadway conditions have resumed and work zone speed limits and restrictions no longer apply. G20-1 (END ROAD WORK) and G20-2 (END CONSTRUCTION) are the standard terminal signs for California TCPs. They are placed at the downstream end of the termination area, just past the last channelizing device or transition.
California Field Use Notes
G20-1 or G20-2 is required at the end of every work zone. Its absence is a common plan-review deficiency. Some agencies prefer G20-1 for short-duration work and G20-2 for longer construction projects, though both are acceptable under the CA MUTCD. When a reduced speed zone ends, the G20 sign reinstates normal speed.
