Clever Cycling Stuff: Cycle Bypasses

It’s always nice when you can get an advantage over motor traffic by cycling instead. Some people riding already do this by sneaking through intersections when other traffic is stopped. This doesn’t tend to do much for cycling-motoring relations (as has been implied by recent events in Auckland), but there are ways to legitimise these behaviours via special cycle facilities.

The light’s red… but bikes can keep going

In Christchurch, there are a couple of neat examples of how this can be done. Firstly, out in Linwood, at the Buckleys Rd – Russell St intersection, there is a cycle bypass of a signalised T-intersection. The bypass allows riders at the top of the T to go around the intersection via a shared path shortcut.

Another common issue is turning left on red; again it’s common to see a bike rider sneak around the kerb corner. However, until we see a law change to allow that all the time, you’ll need a special slip-lane to do it legitimately. Here in Christchurch, one of these has already been created:

Wanting to turn left… just ride the red carpet

At the Moorhouse-Waltham-Barbadoes intersection, a slip lane is provided on the Waltham Road approach to allow riders to hop up onto the footpath and go around to Moorhouse Ave. The design is fairly good at minimising the potential for conflicts between walkers and riders.

These kinds of little advantages are fairly common overseas. For example, here are some bypass facilities from Odense in Denmark:

T-Intersection bypass: “undtaget” = “exempt”

“Free turn” slip lane for cycling

These types of facilities are relatively easy (and inexpensive) to implement. So they could possibly form part of the “quick wins” Cycling Targeted Improvements planned for Christchurch.

What do you think about these cycle bypasses? Any other places where they could go in Chch?

  1. Credit to the well meaning engineers who devised these silly workarounds; but let’s not get too excited about awkward, expensive bricks and mortar solutions whose sole purpose is to bypass stupid road rules.

    It’s the ‘bicycle exempt’ signs from Europe that show real cleverness.

    The need for the workaround is particularly stupid in the ‘top of the T intersection’ situation, where a bicycle going straight cannot possibly endanger or be endangered by anyone else (after giving way to pedestrians of course)

  2. I still think this is fantastic and all credit to the traffic engineers or whoever put these in place, we need many more so cyclists are seen as able to get safely around the corner without having drivers swear at them etc when they turn left with nothing coming. (As drivers can legally do in America on a red light also). this is a good thing.
