Where would you like some Separator Posts?

A few weeks ago we talked about the City Council’s “Targeted Improvements” (or “Quick Wins”) programme that is being rolled out. One of the tools that fits in very well with this programme is cycle lane separators, as previously trialled in a couple of places in Christchurch. Now the Council would like some feedback on where some more could go in.

These seem to work well - so where should we put some more?

If you recall, the intention with these separators is to make existing cycle lanes friendlier to use by actively discouraging/preventing motorists from encroaching on them. Typical locations are:

  1. On the inside of a curve, where traffic cuts the corner
  2. On the approach to an intersection, where left-turning traffic blocks the cycle lane

Following on from the successful trials at two locations, the City Council are keen to identify further locations where problems exist that the separators could improve. From this they want to create a list of candidate sites that will then be assessed for prioritising and implementation.

A combination of low “Riley kerb” and high “flexi-post” delineators was previously trialled but, for now, the intention is to just use the flexi-posts. At some locations, sandblasting and re-marking of cycle lanes will also be needed to achieve desirable widths (the posts do have the effect of narrowing the perceived available cycling width). Current funding this financial year might only achieve about 10 intersections (say, two approaches to each) and maybe another 12 curved cycle lane sites. The amount of funding for these in the 2014/15 year will be reviewed later.

It’s important to appreciate that these separators won’t necessarily be the best option for every location. Complications like parking and driveways for example may make some locations tricky. Ultimately on the Major Cycleway Routes we may be looking for a higher standard of cycleway to attract new riders, e.g. using more physical separation. Flexi-posts are a very cost-effective option to improve the cycling environment, but they may not be a sufficient level of cycleway separation in every case.

Some of the more notable factors that should be considered for suitable sites include:

    • Routes that form part of the planned cycling network in the Chch Transport Strategic Plan.
    • High rates of cycle lane encroachment by motor vehicles
    • No adjacent on-street parking or major accessways
    • Locations predominantly for “everyday” cycling, with good cycle count numbers
    • Sufficient advanced visibility of the separators (so they don’t become a hazard in their own right)
    • An adequate width cycle lane (or available space to make it suficiently wide)
    • Probably not preferred in higher speed environments (say, >60km/h)
    • Ideally not sites that will be reconstructed again soon (e.g. SCIRT works), although they could be an interim pre-cursor to a later Major Cycleway Route.

It couldn’t hurt either if the sites were in locations where they can be very conspicuous to the general public as well (e.g. on busier roads or near major activity centres) – a high profile for cycleway projects is all good PR…

Not just the Major Cycleways - plenty of other routes are part of Chch's planned cycleway network

Based on previous Council investigations and your fantastic feedback to our earlier posts, the City Council already has a fairly good list of potential sites for separators. For example:

    • Various inside curves along Centaurus Rd, e.g. #141, #206
    • New Brighton Rd / Marshlands Rd intersection eastern approach
    • Antigua St / Moorhouse Ave intersection north/south approaches
    • Memorial Ave cycle lane near exit from Fendalton Mall
    • Various inside curves along Wairakei Road, e.g. #40, #96
    • Annex Road lefthand into Birmingham Drive
    • Clyde Rd / Creyke Rd intersection – north/south approaches
    • Bealey/Fitzgerald/London/Whitmore intersection approaches
    • Kahu Road bridge @ Deans Bush
    • Greers/Northcote/Saywers Arms intersection east approach
    • Ilam/Middleton/Riccarton intersection north/south departures
    • Lincoln/Lyttelton/Wrights intersection NW/SE departures

If you have some ideas for where these separators could go, post a comment on this page (“me too” comments supporting previous suggestions would also be helpful). We’ll make sure that the City Council has a look at the collated suggestions.

Milton/Strickland intersection - another potential site?

Note that the sites have to be on local (Council-controlled) roads, not (NZTA controlled) State Highways. So that rules out the likes of Brougham St, Halswell Rd, Dyers Rd, Curletts Rd, Yaldhurst Rd, etc. You can still always contact NZTA to raise any concerns about cycling issues on the State Highways – see our separate post about reporting issues to other roading agencies. Maybe they’ll take the hint and incorporate some separators along the State Hwy cycle lanes…

Where else would you like to see some cycle lane separators?

    I note that separate cycle lanes are shown on the ChCh Transport Strategic Plan for the Spine road from Buchanans Rd to Yaldhurst Rd through the new Living G Yaldhurst zone. This is also required by the City Plan including for the loop road with the requirement for these roads to also be strategic bus and commercial traffic routes.

    I would like to see the Council ensure the remedying of these roads as they have erroneously and dangerously completely eliminated the cycle lanes through the busiest section of the spine and loop roads. Dead-ending of the existing cycle lanes causes deadly pinch points that no separator post can remedy.

    Me too for Kahu Road bridge @ Deans Bush. Another about 50m travelling west on Kahu Road as bridge is the first pinch & the following left bend the second.

      I would support some at Kahu Rd bridge. This is a popular route for uni and also Girls/Boys High students.

        It’s been better through there last week because the road works cones have made it quite narrow, forcing all users into one lane. I’ve centred myself in lane & adjusted speed to exactly 30kph. Has been much safer than the all too common top of bridge or corner squeeze. Have however had one honking car because I was too slow………I’m guessing they accelerated rapidly to 70-80kph once clear

    I would like to see separators for the cycle lanes at the roundabout on the Ferry, Dyers and Tunnel Road. I am forever being squeezed by traffic drifting into the cycle lane and this route is used by a lot of cyclists.

    This may not be so much for separator posts, but in terms of quick wins:
    – heading east on the corner at Cracroft on Cashmere Road – a popular recreational cycle route which is very dicey on a bike. Currently no cycle lane
    – Barrington St to Whiteleigh Ave – join the cycle lanes. I can’t believe that with all the millions they spent on the motorway overbridge that they couldn’t include bike lanes.
    – separator post on Antigua St heading south, for left turning traffic into Brougham St (diagonally opposite the other posts at the top of Strickland St)

      me too, for separator posts on Antigua St heading south, for left turning traffic into Brougham St and Antigua and Moorhouse North and South bound

      In fact, put them wherever you can and paint the lanes red or green, it deters drivers from driving in them immensely if no separator posts or riley kerb exists.

      Keep up the good work, lets encourage more cyclists on the road as the more separate cycle lanes there are the more we are seen by motorists and the safer we all are.

    Please have a look at the following location – going from Bealey Ave to Harper Ave.
