Ok, very minority interest item here, but given the Dom Post reported on it.
The high occupancy vehicle lanes through Mana should be converted into standard clearways. Two full lanes in the direction of peak flow. Short high occupancy vehicle lanes are ridiculous.
Meanwhile, congestion at Paremata/Mana continues to be relieved by the upgrade from Paremata to Plimmerton that cost $25 million, instead of what politicians were advocating - Transmission Gully at over $1 billion. See they know so well how to spend your money.
