Garden Walk is two-way

Garden Walk is a two way street for all but the last few metres at it's junction with Victoria Road. At that end there is a cycle bypass to the no-entry. It's a bodge up that only transport planners understand.

I've experienced it myself, but a resident of the street tells me of her frequent problems with aggressive oncoming traffic (mostly van drivers) that barge at her as she rides up the road. When she tries to point out how the street works they don't listen and challenge her knowledge because of her french accent.

I've suggested these two signage solutions...

Blue signs...

Big bicycle markings on the road...
