there is no specific feature on Google Maps that indicates a "faded blue line." However, Google Maps regularly updates its features and interface, so it's possible that new features have been introduced or that there are variations based on location or user settings.
In general, Google Maps uses different colored lines to represent various types of roads and routes. For example:
- Blue Line: Typically represents major highways or interstates.
- Green Line: Indicates regular streets and roads.
- Yellow/Orange Line: Can indicate secondary roads or roads with slower speed limits.
- Red Line: Often used to show major arterial roads or highways with high traffic volumes.
However, if you are referring to a specific feature or line that appears faded blue, it could be related to experimental features, route options, or user settings that were introduced . In such cases, I recommend referring to the official Google Maps documentation or reaching out to their support for the most up-to-date information on any specific features you're encountering.
