When Upper Harbour Drive fills with cars… blame the bike lane?!

When Upper Harbour Drive fills with cars… blame the bike lane?!

Bike Auckland

[This is a cross-post from Transportblog’s Matt Lowrie, who rides Upper Harbour Drive regularly. We know many of you do too, and would really like to hear your thoughts on this so we can report back to AT and the Local Board.]

Last week, the Upper Harbour Local Board passed a resolution (below) to try and get Auckland Transport to rip out recently installed cycle lanes near the intersection of Upper Harbour Dr (UHD) and Albany Highway. It’s a section of road that I am very familiar with as I use it regularly when I ride to work.

That the Upper Harbour Local Board:

request that Auckland Transport urgently revert to the board with an interim solution regarding the potential to reinstate the second vehicle lane near the intersection between Upper Harbour Drive and Albany Highway, by evaluating options including a shared cycle path and walkway.

The cycle lanes along UHD were installed last year and I’ve previously written about how AT removed the existing broken yellow lines (BYLs) when installing the cycle lanes resulting in locals parking in the cycle lanes. This issue wasn’t unique to UHD but something good came from it with AT agreeing to change their policy and mark BYLs on all cycle lanes.

So what’s the problem this time?

This year UHD has been noticeably more congested this year than it has in the past. On the worst day I’ve seen the slow moving queue was over 2km long* although that’s an extreme – I’ve definitely been thankful to have been on my bike and not caught up in that.

Drivers and residents have been complaining to the local board about the congestion and all have taken a correlation equals causation position on the matter. In their view the problems all stem from the creation of the cycle lanes. You can see the old layout on the Google Maps image below, where for about 200m prior to the intersection there were two lanes, one for each direction.

And here’s what it looks like now from Streetview. The cycleway extends to the intersection. You can still see the old lane markings.

Here’s what the local board chair told our friends at Bike Auckland:

Since the upgrade we have had too many complaints to count and have asked the residents for patience. We met with representatives several months ago, but the issue has only worsened. The peak time queue is at pre motorway levels.

The issue is the merge to one lane meaning cars wanting to make a free left onto Albany Highway have to wait. The police have been involved due to driver behaviour with people reported driving up the berm along the footpath etc. it is unsafe. There are corresponding issues on Albany highway with cars driving straight ahead in the right turn lane to jump the queue but that has nothing to do with the cycle lanes – it is the function of the junction as a whole.

It is noted that since the road changes there is significant additional traffic using it from the several hundred new homes in Hobsonville, Whenuapai and beyond. We have substantial delays on all of our arterial roads but this one has been exacerbated by the on road cycle lane.

What we are investigating is whether we can relocate the cycle lane on to the footpath and reinstate the free left. We do not wish to remove the cycle lane. Neither the footpath nor cycle lane is busy at peak times with commuter traffic but is well used at weekends by recreational cyclists. Over time with the many hundreds more homes planned in the surrounding area the delays will get longer and we will need to look at bus priority measures.

I don’t think it is car vs cyclist in this case but getting the most out of what we have with a population growing almost daily.

Even the local Community Constable is blaming the cycle lanes and pushing for the cycle lane to be removed or able to be used by cars. [Click to read full post]

Below are some observations I’ve made from travelling through here:

  • Northbound towards the commercial area (over 15k jobs) north/east of Albany Highway is frequently more congested than southbound traffic. In the few times I’ve driven to work I’ve also noticed the left turn off the motorway is normally much more backed up than the right turn.
  • I’ve frequently observed cars simply ignore the cycle lane and try and use it as an extra vehicle lane- ultimately they end up blocking the cycle lane.
  • The footpath is too narrow to be a shared path and widening it wouldn’t be cheap and would lead to poorer outcomes for those on bikes or walking (not many). For one it would likely increase the risk for those like myself who are turning right as we would have to cross the slip lane reach the right turn lane.
  • Returning the road to a three lane configuration would also likely require the removal of the westbound cycle lane.
  • If it’s new development which is causing the issue, then any change is only likely to have short term benefits at best before it’s all congested again.

By now, you might be asking, “but didn’t we just build a parallel motorway – why aren’t people using that?” The image below is from Tauhinu Rd which crosses over SH18 at the southern end of UHD. Like UHD it only seems to have become so congested this year.

This changes the question to “why are both of these routes suddenly seem so much more congested than they were last year?”

The answer to that is actually quite simple, and is one of the oldest reasons in the book – roadworks. For some time now Auckland Transport have been working on Albany Highway, and since about the middle of last year that work has focused on the southern section which is the one that most affects traffic to and from the commercial area. Those road works are due to finish later this year. That needs to be completed before any assessment is even considered.

It’s also worth pointing out that traffic isn’t always bad. This was taken last week at the same time and day of the week as the first photos. It was also taken the same day as the image above. The road was empty all the way to the intersection. Perhaps the congestion on UHD was being exacerbated by people trying to use UHD as a rat run to avoid the motorway?

I’ll obviously be watching closely to see how Auckland Transport respond to this request from the local board. It seems to me a case of correlation does not equal causation – and if it is decided that the only way to get bike infrastructure is only if it never impacts drivers, then it will be very much longer and more expensive to make any meaningful progress.

* the 2km long queue appeared to be the result of the drivers rubbernecking at the police stopping drivers who travelled through the intersection illegally.
