Ask Phoebe: AT traffic flow trial in Parnell

Parnell Rd.

Can you please explain how the traffic-lane changes between St Stephens Ave through to the Ayr St intersection are supposed to have improved traffic flow in this area? Since a single lane of traffic was introduced, from what was previously a merge-like-a-zip two-lane arrangement, traffic now backs up down Parnell Rd and also down St Stephens Ave to the point that the intersection of St Stephens Ave and Brighton Rd is becoming log-jammed. Declan Cahill, Parnell.

As part of the whole-of-route approach for the public transport in the area, Auckland Transport was testing signal options to try to improve traffic flow from other directions.

They found that some changes caused more delays to traffic flow than were acceptable. AT has now amended the signals to help relieve the flow on Parnell Rd.

The Parnell Rd southbound bus lane is not operating yet and the current road markings allow for drivers to continue as before. AT will also put in temporary signs to inform drivers of the new layout and expected completion date.

There are several large vertical wooden panels either side of the railway line just before the Ellerslie train station (southbound) and either side of the Ellerslie bridge over the motorway. Can you tell us what their purpose is please? Mike Protheroe, Auckland.

The Transport Agency is widening the Southern Motorway with an additional northbound lane from Ellerslie-Panmure Highway on-ramp to just after the main highway overbridge. The panels are sound and safety barriers.

The cost of the motorway widening is $12 million. It is due for completion in March next year.

On the rail tracks parallel to Tamaki Drive, near where the road bridge goes over the lines to The Strand, I've noticed a couple of handsome-looking steam locos and wondered if you could tell me if they're here to be restored? Dave Bennett, Auckland.

These engines, originally from South Africa, are the property of Mainline Steam, a privately owned heritage train organisation.

The engines are awaiting removal to a new home, the location of which is still undecided, after the lease on the Parnell site was terminated.

All the restoration is being done by volunteers. For more information on these and other engines visit the website at mainlinesteam.co.nz
