Lower Hutt CBDs roading network. Almost every interesection in Lower Hutt CBD is a roundabout. So in rush hour it is total grid lock, as people enter the round about even though they can't exit it, blocking other entry paths. Even though you aren't supposed to enter a roundabout if you can't exit it.

 

Before the Circles there was 40,000 sets of traffic lights, traffic flows were terrible. The worse issues in the Hutt are the Melling interchange(soon to be resolved, the dopey Saturday market and the Esplanade. Oh and of course Queensgate.
