In Alberta township surveys, how often is there a north-south road?

In Alberta township surveys, roads are typically established based on a grid system that facilitates land access and administration. A fundamental feature of this system is the placement of roads at specific intervals to ensure practicality and ease of navigation.

The correct answer indicates that a north-south road runs every mile. This is consistent with the standard design of township surveys, where sections of land are often set up in one-mile-square plots. The north-south roads are strategically positioned to allow for accessibility between sections, making it easier for agricultural transport, residential development, and overall land use. This layout is fundamental for land divisions, assisting both the government in managing land and the public in navigating it.

The other options suggest more frequent placements of roads, such as every half mile, every two miles, or every quarter mile. While these are plausible spacing concepts, they do not align with the established pattern of one-mile intervals for every north-south road in the standard grid system used in Alberta's township surveys. Thus, the one-mile interval achieves a balanced approach to accessibility without overcrowding roads, which is vital for rural infrastructure.
