What spacing should bridge hangers have when ambient temperature is above 32 degrees Celsius?

When ambient temperature climbs above 32°C, cables expand and tend to sag more between supports. To keep sag within allowable limits and maintain proper clearance, the spacing of bridge hangers is reduced to six feet. This closer spacing helps prevent excessive droop that could lead to contact with structures or other cables, while still being practical to install. Spacings like twelve feet would allow too much sag in hot weather, while very tight spacings (two or three feet) would be unnecessary and costly for typical installations.
