Public consultation has just ended on the Blanchardstown to Phoenix Park cycle route — this route is ambitious for tackling a confined main route and giving space over to cycling, but it’s also full of missed opportunities and disregard the Manual for Urban Roads and Streets, which the council are obliged to follow.
Possibly the worst element of the route shows a distinct disrespect for the law, or disrespect for cyclists — we’re not sure which one it is. In any case, putting cyclists into share space which leads into zebra crossing is disrespectful of road safety. Bicycles legally should not be cycled across zebra crossings, but the Fingal County Council directing cyclists into the crossing will likely give many cyclists the wrong impression. Motorist rightly won’t be expecting to have to yield to cyclists on a zebra crossing. Combining those two is looking for trouble.
The project largely comprises of segregated cycle paths, but it’s low-level segregation overall. In the Netherlands routes like this would be fully segregated with cyclists protected at junctions or in Copenhagen the segregation would at least continue right up to the junction. Here the segregation ends before junctions:
On sections of the route where there’s very limited space cycling is mixed with motor traffic in the one lane, with large bicycle logos painted on the surface and 30km/h speed limits.
But the 30km/h zones doe not start/end at the points where bikes are mixed with motor traffic and there’s very low amounts of traffic calming between the entry points:
Elsewhere there’s elements of excellent design, such as a bus stop bypass which is a standard feature in the Netherlands (see here and here), this keeps conflicts betweens cyclists and buses or bus users to a minimum:
But the island bus stop design is only put into limited use along the route — in most cases bus stops interrupt the cycle route. Often this is done where there’s loads of space for bus stop bypasses. Here’s a good example of a location where the planned route does not included the design and our example of how bus lane bypasses could have been used…
Our rough outline of a possible revision:
Shared use — where cyclists and pedestrians are mixed — is also used on the route, sometimes where there’s no room for full segregation. But in other locations, shared use is chosen where there’s ample space for full segregation. The main example is at Laurel Lodge at the park just before the route goes over the railway and the Royal Canal — and it’s a bit of a mess:
At the Castleknock Road gate to the Phoenix Park, we have a suggestion which would require guts from all involved but mainly from the OPW, who manage the park:

The current railings in the gate structure between the road gates and the pedestrian gates could be made into gates to allow for a fully-segregated cycle paths. The current segregated cycle paths in the park could then be linked with the segregated paths proposed outside the park.
The current plan for the cycle route will push people cycling into a conflict with motorists rushing to enter or exit the park quickly before the traffic lights change. People on bicycles heading towards the park will also have to deal with being put in a sub-standard width cycle lane between two traffic lanes: It may wrongly be presumed that 1.75 meters — the new default / minimum cycle lane width — is ok here, but it’s not…
This is the Width Calculator in the NTA Cycle Manual:
The 1.75 meters comes allowing for the “inside edge” space for a kerb or a channel gully of 0.25m, the single file “cycling regime” of 0.75m, and the “outside edge” of 0.75m in a 50km/h zone and allowing for a 3m wide traffic lane.
But in the case of a cycle lane which is between two traffic lanes, there’s no inside edges. There’s now two “outside edges” between bicycles and motor traffic. The default then for a cycle lane between two 3 meter traffic lanes in a 50km/h zone is 2.25m. The inside traffic lane in this case is slightly shy of 3 meters — it’s 2.95m — so even if we were to expect and allowed for slower traffic in the lane because of the slight lane width reduction, the cycle lane should not be narrower than 2m as there will be buses in the inside lane.
Regardless of the width, the planned setup is hardly attractive to cycling on your own or with children to the park — many will choose to use the footpath where the segregation ends.
All of these issues would be resolved if the project was extended in scope to include the park gates and fully segregated cycle paths were used. Something like this:
Last year the Department of Transport issued a circular (RW 6/2013) pointing out that the Manual for Urban Roads and Streets is mandatory for all local authorities on all urban roads and streets. Fingal County Council seem not to have gotten the memo. The manual includes the following:
- In general designers should:
- Provide crossings on all arms of a junction. Reduce kerb radii, thereby reducing crossing distances for pedestrians and slowing turning vehicles (see Section 4.3.3 Corner Radii).
- Omit left turn slips, which generally provide little extra effective vehicular capacity but are highly disruptive for pedestrians and cyclists. Where demand warrants, they may be replaced with left tuning lanes with tighter corner radii (see Figure 4.59).
- Omit staggered crossings in favour of direct/single phase crossings (see Section 4.3.2 Pedestrian Crossings).
- Omit deceleration lanes. These are not required in low to moderate speed zones (i.e. up to 60km/h).
Fingal County Council have however chosen to retain six slip turns without notable changes beyond minor paint markings differences:
So much for the urban design manual being mandatory?
The route in general is an improvement to what’s there now, but it’s so close to being a lot better. There’s sometimes understandable compromises, what’s planned however goes beyond compromises: it uses shared space where there’s room for cycle paths, it also does not bother with bus stop bypasses where there’s space, it messes about directing cyclists into zebra crossings and the segregation ends at key points where people need it the most.
Hello Reader... IrishCycle.com is a reader-funded journalism publication. Effectively it's an online newspaper covering news and analyses of cycling and related issues, including cycle route designs, legal changes, and pollical and cultural issues.
There are examples, big and small, which show that the reader-funded or listener-funding model can work to support journalism -- from the Dublin Inquirer and The Guardian to many podcasts. To make it work for IrishCycle.com, it just needs enough people like you to believe!
Monthly subscriptions will give IrishCycle.com's journalism a dependable base of support. But please don't take free access for granted. Last year IrishCycle.com had an average of 15,800 readers per month and we know our readers include people who cycle and those who don't, politicians, officials and campaigners.
I know only a small percentage of readers will see the value of keeping this open enough to subscribe, that's the reality of the reader-funded model. But more support is needed to keep this show on the road.
The funding drive was started in November 2021 and, as of the start of February, 210 readers have kindly become monthly subscribers -- thank you very much to all that have!
But currently, it's only around 1.3% of readers who subscribe. So, if you can, please join them and subscribe today via ko-fi.com/irishcycle/tiers
