Komoot, by design, tries to take you to discover new roads, especially when they are not very busy.
This stretch of secondary road is suggested by default as a connection between Noragugume and Ottana, instead of the (slightly) longer SP33. Unfortunately, the segment has poor pavement (decent only in the first third of the segment) and passes through agricultural land with numerous dogs jumping fences and chasing people. Traffic is present, however, as the second half of the segment serves numerous industrial plants and construction sites (September/2024), with many heavy vehicles going back and forth; aided by the narrow road, the experience is also made more dangerous than the state road, which at this point I highly recommend taking.
