See https://wiki.openstreetmap.org/wiki/Key:maxheight#Non-numerical_values for some alternative tagging styles And extending this quest to roads under bridges was recently implemented, though this is not released yet.

Hi Ed,
Yes, that looks like it.
Many thanks for finding it for me; I've been a bit busy in the last few days.

I am pretty sure that I remember checking bridges in my area some time ago,
using a tool that someone kindly provided, which flagged up all bridges, where
the clearance height was not specified in OSM.
I regret that I cannot now find the link.

Saw this and thought it might suit a small virtual project - to
check/add bridge heights from mapillary images or similar might be useful.
And maybe network rail have a longer list / more info?
Cheers,
Neil

It had to be pulled back and exit the way it came in. Whether lorries of this size should even be on these roads is another matter :) -- Lester Caine - G8HFL - Contact - https://lsces.uk/wiki/Contact L.S.Caine Electronic Services - https://lsces.uk Model Engineers Digital Workshop - https://medw.uk Rainbow Digital Media - https://rainbowdigitalmedia.uk ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb

After many years looking out of the window travelling from NCL to EDI on the East Coast Main Line (ECML is a common abbreviation - e.g. in bridge references), I'd give a special mention to the rural level crossings which have two poles and a line of suspended bells across the track to (hopefully) alert any machinery operators that Something Bad Is About to Happen! 'got_bells_on = yes' perhaps? :-) Sadly, I don't have specific examples, just the memory of countryside, likely either side of Berwick. A little more seriously, several types of infrastructure have over-height detection kit - e.g. the Tyne Tunnel has broken beam detectors across the carriageway about 1km from the tunnel portal. Look for the poles with two sets of broken beam kit abode the 30 sign in this image: https://www.mapillary.com/map/im/LdqV481D4eAHnvBvrcgKEg This height restriction is more complex as to add a safety cell (evacuation route) to the original Northbound circular bore, the lanes were moved off-centre. This means lane 1 has greater clearance than lane 2 - creating the regular task of replacing the signage above lane 2 when a lorry driver decides to illegally overtake! donk, donk, donk, crash... And yes, the approach bridges are 'got_bells_on = yes': https://www.mapillary.com/map/im/QvgXLAvET7V3xjEdX2Ir_g The question with the TT is how to tag 5.1 m lane 1 and 4.0 m lane 2 on a single highway=trunk; lanes=2? It's not tagged today, so adding the 5.1m to the trunk would make sense as 4.0m would give a false routing. I'm not personally a fan of the analagous way lane tagging is used to model the A1 further north (turn:lanes=through|through|right), as it's not human readable on most renders (#include ).

Motorway bridges for example. Maybe we need an unsigned tag so that these can be elimiated? A hay lorry managed to hit this (unsigned) one a few years ago.
