On the Sustrans (Scotland) site you can now obtain a complete list of all milepost locations for the entire UK. The raw data is supplied as a KML file, which you can import into GIS and mapping systems.
I had a go myself, and managed (to my surprise) to create a map using the KML locations, the Open Street Map data, and the umap website:
If you make anything interesting out of the Sustrans data, add a link to it in the comments!
Sustrans Scotland are leading the way in providing open data for the National Network. Although the milepost page and data for the UK is available only on the Scottish web page at the moment, it will soon be available on the web pages for the other regions.

Please get in touch with me. I may have new information for you. A lot of what you are looking for may have been common knowledge a years ago but Sustrans staff no longer know it! But you have taught me how to decipher all the coded messages now! Clyde

Sorry about the long delay – I’ve been away. I was hoping you would email me since I didn’t want to give too much away on this blog. As far as I can see from your posts, you still don’t have all the TT disks – is that right? I have all 50. I tried to solve the messages by using frequencies of letters but since you cannot tell which way the messages are running and because many of the letters have mirror images which are also letters of the same alphabet, this didn’t work! I gave up some time ago. I never thought of researching known alphabets as I thought this one was CH’s own invention.

Hi Clyde. I’ve only managed to find about half of them so far. I thought it would be good to put a record of this puzzle on the internet — not so much the solution ( which is just a poem that you can easily find if you google it) but more the process of decoding and solving the symbols, and enjoying the journey rather than the destination. If you have photos of some of the disks, I’d be interested to see them. Even Sustrans have largely forgotten about the Millennium Time Trail. Cheers!

Hi James. Are you the same James that I’ve just emailed? The prize was some sort of trophy which used to stand on the desk of one of Sustrans’ employees. For a while I had an email ‘conversation’ with her, some years back, but it was clear that she knew nothing of the TT puzzle nor of Charlie Harrow.

There are four Mileposts in the Swale region of Kent that do not appear on that map, nor any other list I have had from Sustrans.
There are also Mileposts marked in Medway that are either no longer present (if indeed they ever were) or have since had some minor relocation.

Sustrans aren’t updating the list, as far as I know, since the millennium trail is no longer a current project of theirs. Cosmo from Sustrans says that there are disks in their warehouse. And I’m sure the odd disk is decorating someone’s shelves…
Perhaps the unofficial Open Street Map wiki list could be updated by those who know about unlisted disks…

OK, pb. I can send you photos of all the disks – but how? Can you attach them here? I’m not used to WordPress blogs. I will also be emailing them to James.

Hi Clyde. I have been sent your photos of the pictures of the discs which has been massively useful, thank you! I am, however, trying to fill the gaps where discs have gone missing and have a potential method of 3D printing new discs. I sent the printer operator the photos but the quality isn’t good enough for printing. Is there any chance you’d be able to scan them, or at least the one I’m getting printed currently (Leo from series 4), so we can make quality discs?
You can email me at cosmo.blake@sustrans.org.uk
Kind regards

Hi, Just to say that MP1143 is only half a milepost so no disk. In 2000 we were the volunteer group of the year and got a bronze milepost like the ‘Fossil Tree’ but no idea where it is now! We also got a bike trailer and I still use that regularly. Tim

We have some of these sculptures in the office and I wondered what they were for – now I know! That sounds like a well built bike trailer! I’ve had some fall apart on me in the past..
Which region is MP1143 in? I can pass it on to the correct office to note. thanks, Cosmo

Hi Cosmo,
The half post MP1143 is in Walsall on the corner of The Broadway and Delves Road.We currently have Pat Wilson in Walsall painting our milesposts and she has done a brilliant job on two so far. I could send you photos if you have and email address?

Hi
I wonder if you still have the KML file of the milepost positions, I can see your wonderful map and cant find a link on that original page you reference.
I have a mad idea to visit all the mileposts over time and would like to create a database of locations

Thanks very much for the audit tool link, very useful. many of the old locations dont appear totally accurate and I’m now creating a new location map based on the open source locations where they seem to have audited most of the locations.
Interesting to see how many are now missing.
Now the for the steady process of producing a database of locations for myself, and anyone else who might find it useful. looks like I have visited just over 100 so far, so should keep me busy. 😉
Thanks again.

This is fascinating. I am really interested in visiting as many of these as possible. Does anyone have an excel (or similar) list so that I can keep track of my visits?
I have asked Sustrans, and though they are ever so helpful, they have no such record – I’m not sure if that’s what their original
Sponsor had in mind!
I’d also love to know how they decided where to put them. There are so very few in my area, despite some big routes passing through.
Thanks for your help.
Sharon.

Yes, Sustrans claimed to know nothing about it when I contacted them initially. More recently we’ve been more fortunate in having some contact (Cosmo in these comment threads). I think there are lists floating around – OpenStreetMap probably. Unfortunately an up-to-date list (aware of missing ones) isn’t available to my knowledge- and would be a formidable undertaking to make!

I have been working on a spreadsheet based on the opensource data and correct positions, now I see there is a new public mapping tool from Sustrans being publicised. https://sustrans-uk.maps.arcgis.com/apps/dashboards/68e25983f2e64bf1aa76058bb60949ef
It is far from perfect with some posts missing and even some monuments added that were not original Millennium posts. Strangely all the posts in England have been re-numbered with an X-prefix (the ones in Scotland remain as before) I have started cross referencing these numbers to the old ones.
I wondered if your new spreadsheet had these new numbers included in it?
Thanks

There is no X prefix on the ones I downloaded to build the spreadsheet. I have not compared the data to earlier lists.
