Highway 100 (Traditional Chinese: 100號國道) is a 4-lane controlled access freeway, running north-south between Highway 505 and McNaughton Line in the Mapleview Census Metropolitan Area. Like a regional road, it is metropolitan-area funded, but it is at an expressway standard. Highway 100 is in the process of being upgraded to a regionally-funded 500-series expressway. It is proposed to be renamed as "Highway 500" in the future.
