The RAVeL L141 is closed for important road work here. Big barriers, no way to pass. Closed at Rue du Pont and closed at Rue de Charleroi. I placed two pins at each place where there is a barrier. It's been this way for 3 weeks now. Looks like it's going to take a while.

A diversion has been put in place, with diversion signs indicating the way to follow.

When at Rue du Pont, the diversion goes like this:
- Go down Rue du Pont until Rue Emile Hecq
- Turn left onto Rue Emile Hecq
- Go through Place Comte Cornet
- Turn left to follow the street Rue Joseph Milhoux until you reach Grand Route
- Turn left onto Grand Route then Rue de Ways straight ahead
- Turn left onto Rue de France
- Follow Rue de France until Rue de Charleroi
- At some point, Rue de Charleroi leads back to the RAVeL 141

When at Rue de Charleroi, the diversion goes the same but reversed – except the diversion goes through Rue Jean Mintens to reach Rue de Ways, instead of Rue de France (one way street). 

Not sure how to edit it to create a diversion. I'd rather leave it to more experienced users. Thanks
