Canada - Fix Duplicated Highways Challenge

Communities Canada

Hello OSM Canada,

We identified highway segments that have overlapping geometry within a 0.5-meter buffer. There are 299 tasks for this challenge: Canada - Fix Duplicated Highways

Overlapping highways can cause:

  • Confusing navigation: Incorrect or confusing directions.
  • Visualization issues: Inconsistent map rendering, such as doubled roads.
  • Data processing errors: Errors due to differences in tagging between duplicated highways.

Most cases can be solved by realigning nodes or portions of highways. In some situations you may need to zoom in closely to see the issue as shown in this example:

If you’re unsure about a complex situation or if there’s outdated aerial imagery or street level sources, flag the task as Can’t Complete.

Reach out with any comments, feedback, or questions about this challenge. Happy Mapping!

Thank you,
David
