Bridge Weight/Height Restrictions

Hi, could not see this as a topic. We have several minor bridges within a few miles of my home that have weight restrictions and with one bridge with a height restriction in Norwich that has suffered a vehicular strike that has closed the road to through traffic. I can not find any current way to add this data. I feel this is quite an urgent addition to the map data. Are there any plans for this?

Waze doesn’t currently support height/width/weight restrictions, so there’s no way to mark these in the map data. Remember that Waze is aimed at car drivers for whom such restrictions generally don’t apply, and as much as some of us would love to see Waze evolve into a more fully-rounded satnav system suitable for any type of road user, the Waze devs have other priorities and seem quite happy to keep it as a car-oriented system.

As an idea:
This Segment has a 2ton mgw limit, so it has been restricted to vehicles that will be over 2ton ie busses, vans and trucks.
You could do that with sections under certain types of bridges too…?

Maybe then they could bring out a Lorry and Bus version then. As well as height, width and weight it could have low bridge as in hump back bridges not suitable for low trailers and Bus lanes.

It doesn’t restrict any vehicles :shock: You may have mis-understood the comment from Twister. Waze only supports two vehicle types at present, private car and taxi.

Whilst you can input restrictions for trucks, buses, HOV (high occupancy vehicles), trailers and several other types, Waze will completely ignore those restrictions.

As for the 2 ton weight limit are you sure that is MGW, I assumed if the sign does not state MGW then it is just current vehicle weight. 2 ton MGW would exclude a lot of taxi’s (minicabs) around here as Mondeo estates are quite popular, actually it would also exclude some Ford Focus cars!

Using the logic applied to the restriction on that segment we would have to warn Wazers if they are driving anything bigger than a small Ford Focus then they should tell Waze that they are driving a truck or a bus (if Waze supported those vehicle types)

There are reports in the local press that police have been handing out tickets to drivers of some 4x4’s at a 3 ton MGW bridge near me as many Land Rovers have a mgw over 3 tons, but at the same time some Transit vans only have a 2.9 ton mgw so they can use it. That would completly mess up trying to use vehicle types to restrict on weight.

Assuming we could restrict on weight I don’t see how you could reliably use it to limit height. Sticking with Transit vans you can get some with a max gross weight of 4.7 tons that are only just over 2.6 metres tall whereas most Luton vans will have a much lower mgm and will be much taller.

The bridge is 2 ton MGW, and you are right about SUVs they can be 2.5 ton plus mgw. When I was doing My passenger transport exams the theory is 5 people = 1 ton so I can agree that many metrocabs, tx1 and tx2 would be over 2tom MGW. A Diesel Ford Focus estate (heaviest variant) is 1388 kg (curb) so MGW would be 2 ton. There is a problem with commercial vans going over the bridge currently.

I understand that Waze currently only supports PV and TX vehicle types, however as they have integrated the other types into the interface that would suggest we will see more types coming as things move on, so better to apply things when editing sections than having to go back etc… (just to add weight, sorry for the pun, to this statement I would guess I am responsible for the addendum HERE).

Crikey, where did you do your exam, Samoa? :lol: I think you need a new calculator because that’s 200kg per person or over 31 stone in old money :shock:

I believe the EU standard is 75kg per person including luggage.

I quite agree, however I don’t see how you can reliably apply vehicle types to weight limits. In this case with a 2 ton limit (I’m still not convinced that is mgw) it’s a no brainer, but what do you do with bridges with higher limits?

There is a 7.5 ton weight limit throughout the City of London, so should we set all the roads to restrict lorries? What then would we call a 7.5 ton lorry?

In the highway code there is an example sign stating 18T mgw except empty vehicles. So do we limit lorries, RV’s, buses, public transport? Each could be over or under that weight.

What about bridges where there is an axle limit?

2 excuses 1: it was 2002 I did the exam, 2: I missed the 1 from 15 :oops:

Castle Farm Bridge is 2 ton mgw, took a bit to find a street view sign that was legible: Street view from Freeman Rd

There is classification for most of that on the gov.uk site HERE

I just re read that and it makes good sense for potential editing limits… :slight_smile:

The most common MGW restriction seems to be 7.5T, so it makes sense to make that the definition of Truck (i.e. HGV). However, as Waze don’t have any plans to support trucks, we are not mapping any truck or weight restrictions until Waze figure out how they are going to treat them.

Well spotted, the other sign doesn’t state mgw, wonder if that was a mistake on the part of the local authority? If that’s the case this could be one of the few roads where some private cars are allowed but not taxi’s. As I mentioned before I’ve never seen a taxi smaller than a Mondeo or a Passatt both of which are over 2 ton mgw. Interestingly streetview shows two taxi’s about to drive across the bridge (a Passatt and a Mercedes mini bus) and a ML280 that has just driven over. I suspect that most motorists are blissfully ignorant of the weight limit and have absolutely no idea of the max weight of their vehicle. :roll:

I wonder if the police ever hand out tickets here as it’s pretty easy to stop everyone driving anything bigger than a mid sized family car. They do it on Marlow bridge which has a 3 ton weight limit that catches out the locals in Range Rovers.

They never do, we also have a 3 ton mgw Here and there are plenty of vehicles over the restriction that use it too.
