Hi!
From what I read on the "De Lijn" website, these changes are temporary, due to road works ("Nieuwe reisweg tengevolge van aanleggen van fietsstraten." - "Van donderdag 04 augustus 2022 tot woensdag 31 augustus 2022"). Is that correct? In this case, we tend to leave things unchanged, unless there are community members following up closely to restore when needed. This way the map is only temporarily incorrect, instead of all the time after the works have passed.
