Intentionally designed to narrow the lane with the intent of slowing traffic and reducing risk to others – eg pedestrians. Same technique used in vehicle lanes occasionally also.

It’s looking good, at least the bits which are completed.

At the moment, few of the traffic signals are working, like MSR and Clarence crossings.

HJR and Waterloo is actively being worked-on, so its currently terrible but that will pass.

Russley Road is going to be awful – I suggested an overbridge or a tunnel, but that’d be expensive.

Whizzing across Elizabeth in Riccarton was kinda neat.

Wheelie bins are a problem, as are drivers that don’t look both ways. There were more cyclists than I’d normally see out, so even when only partwise competed, the bits that are there are already having a positive effect on numbers.

Personally I’ve been riding Blenheim Road for my commute in the past year or so. With minimal on-street parking, it is surprisingly pleasant and fast, though the traffic bears watching so is not a route for the beginner. As a cyclist, I don’t like to stop… gotta keep the momentum up.
