Where are manholes typically located?

Manholes are primarily located at street intersections because these areas are critical for accessing underground utility systems such as sewer lines, water mains, and electric cables. Placing manholes at intersections allows utility workers easy access for maintenance and repairs without disrupting traffic flow significantly. This positioning also facilitates easier navigation for vehicles and pedestrians around the work site, which is an essential consideration in urban planning and infrastructure management.

The other choices may have some relevance in particular situations, but they do not represent the typical standard for manhole placement. Private property may have manholes, but they are designed primarily for public utilities, making street intersections much more common. Utility poles are not necessarily aligned with underground systems, and while there might be manholes near alleys, they are usually more concentrated at intersections to optimize accessibility to the broader network of utilities.
