Thanks a lot! It's my first time using OSM myself (though I have colleagues at my job that use it a lot more). The reason I tried making a change on this segment is because I saw an new tool done by another organisation that very useful provides an index of the percent of inhabitants living near protected bikeways. I looked at the Brussels Region and my neighbourhood and noticed that a part of Avenue des Bardanes is designated as having a protected bikeway, when I know that isn't true. That's why I tried making a change. Contraflow cycling is allowed and there's probably one or more sharrows painted on the street, but no protected bikeway. 

Anyway - thanks for checking!
