TomTom Duplicated Highways Challenge - May 2026

Hi All,

TomTom has more one MapRoulette challenge to share in May for United States - Duplicated Highways with 590 tasks. In this challenge, tasks were created where highways have overlapping geometry within a buffer zone of 0.5 meters. As seen the example below, in many cases, only portions of the highways overlap and need to be disconnected or realigned.

As always you may encounter false positives, so feel free to mark those tasks as Already Fixed or Not an Issue as needed.

Thanks for taking a look!
