As with other districts in the Fraser Valley, Langley uses a Streets and Avenues grid system, where streets run north-south, and avenues run east-west. Not every street or avenue runs straight through to the next road in the grid, in Langley typically every 8th interval is a major road (e.g., 216 St., 224 St., 232 St., etc.; 16 Ave., 24 Ave., 32 Ave., etc.) creating a pseudo-superblock with a less predictable street layout inside, though this is not an absolute rule - in more densely populated areas major roads are more frequent, such as every fourth interval - 64 Ave., 68 Ave. and 72 Ave. in Willowbrook are examples of this.
