Mount Eden Road is one of our premier isthmus bus corridors, now having a very high frequency. Between 7am and 9am 36 buses depart Three Kings, or nearly one every 3 minutes. Half of all Airbuses also use this corridor giving an extra 3 per hour each way. During the busiest hour there are 22 buses along the corridor, while latest traffic count figures (2006) show there were 1600 cars. With about 50 seats a bus, that means buses carry at least 1100 people, so buses are carrying about 40% of the people in the northern part of Mt Eden Road. Generally in the peak hour these buses are packed with standees, so buses maybe well be carrying half the people in the corridor. Then north of Esplanade Road, Dominion Road buses (except expresses) join Mt Eden Road too, giving an extra 23 buses between 7am and 9am. This suggests the corridor should have full bus lanes the whole way from Three Kings into town. I have already covered the big issues with bus congestion at Newton in a previous post, so I will now focus on the corridor between Mount Albert Road and Newton.
Below is a map of the current bus lanes (green lines), and as you can see they are very erratic (zoom in on the map to see more detail).

While the corridor is 5km long, the sections going northbound only have bus lanes for 2km, while southbound there is only 1km of bus lanes. Therefore only 30% of the corridor has bus lanes, which is hopeless considering the frequency of buses along the corridor. Heading southbound there are none south of Balmoral Road, while northbound none south of Duke Street.
Work to move the corridor towards full bus lanes can be separated into quick wins, short term fixes and medium term fixes as in some areas capital works are required.
There are 2 obvious quick wins.
The first quick win is the ridiculously short timing of the southbound buslane leading to Mt Eden shops. This a roughly 200m section starting at Batgar Road, and finishing where the shops start. It is only a buslane from 4.30pm to 5.30pm, then reverts to parking! This means that a bus leaving Britomart at one of the busiest times of 5.10pm would struggle to make it to Mt Eden before the bus lanes finishes! This should immediately be standardised to the usual time of 4pm to 6pm. However for bus lanes in general I would rather see at least 3.30pm to 6.30pm for evening lanes but that’s another discussion. The short operating hours result in crazy situations like this one taken around 6pm, with one car parked the brief bus-lane.
The second quick-win is regarding the clearways that exist through Mt Eden village (black lines in the map below). There is no reason why these should not be buslanes. The southbound clearway also has silly short hours of operation (4.30pm to 5.30pm again) so this should be extended as well. The northbound clearway is the standard 7am to 9am which is fine for the shorter morning peak. This change would help buses get through Mt Eden faster, and in and out of bus stops much easier.
The short term fixes (3 months to 1 year) are simple extensions of green paint along existing traffic and parking lanes.
Some of the issues encountered with current lengths of bus lanes were highlighted by commentator Steve N in my general bus lane post from February.
“Mount Eden Road/Three Kings route: install inbound bus lane from Three Kings Terminus to Duke Street, to meet existing bus lane. After 0720ish, traffic backs up past Duke Street, including buses – completely negating 5 min frequency.”
So this suggests a northbound bus lane would really aide reliability and speed of the services the whole way north to the city. There is enough width within the kerbs for bus lanes to be added on both sides of the road from Mt Eden village to Three Kings. This bus lane would be very easy to install, as could be done with morning and afternoon parking restrictions and a coat of paint. In some areas the median may need to be narrowed or removed to fit bus lanes on both sides of the road. The only complication is the zebra crossing near Duke Street which may need to be removed. Zebra crossings are not seen to be safe roads with 2 lanes of traffic in one direction. So the only cost would be signalization of these pedestrian crossing, which AT have indicated costs around $100,000.
North of Mt Eden village things are a little trickier as the road is more windy and there are more intersections and pedestrian crossings to deal with. This means lanes need to be wider to accommodate vehicles. Northbound bus lanes can be easily added at least as far as Percy St (where southbound bus lanes start), just by narrowing the median. This looks to be the same for the section between Normamby Road and Mt Eden station. However some areas will require more complex works over the medium term.
The Normanby Road intersection is likely to require the biggest work. There are various islands and turning bays that narrow the road width here, so some capital works are inevitable. I suggest this intersection is in need of major upgrades for pedestrians too. Depsite this being opposite a playground (top right) and the northern entrance to Mt Eden, there are no pedestrian crossings at all. Coupled with the turning lanes, wide curving road and high speeds, this is a very dangerous spot for people crossing the road. I can see it being very difficult for cars to turn in and out Normanby Road at peak times too. Fixing the safety issues is likely to require signalization to add a safe pedestrian crossing point, so signalizing the whole intersection in conjunction with other work and kerbs and islands is likely to be the solution. Careful phasing to give limited priority to Normanby Road will ensure this intersection does not congest Mt Eden Road.
On closer inspection some other areas will also require capital works, such as kerb realignment, especially at intersections such as Boston Road and Esplanade Road. When capital works are done this is a great time to add cycling infrastructure to the corridor as well. Unfortunately like Dominion Road it appears to be difficult to fit quality separated lanes in the corridor as well as bus lanes without major rebuilding works.
So to sum up the volume of buses on Mt Eden Road means it is in need of full length bus priority. Some of the improvements can be done very quickly, however others will need varying levels of capital works. Either way improvements on this corridor can be done for a fraction of the $66 million being spent on the parallel Dominion Road corridor. Auckland Transport needs to come up with a staged implementation plan, showing how Mt Eden Road can move from 30% bus lanes to full length bus lanes over the next 5 years. I would suggest we could could see a big improvement in under a year, and more expensive parts programmed in after that.
