Changes to the DMRB and MCHW web service beginning November 2015

The Standards for Highways website is a convenient, trustworthy destination for all those involved in the design, construction and maintenance of highways to gain easy access to the latest DMRB and MCHW documentation, alerts for updates and access to IANs.

As well as free downloads of documents we are now providing our users with the ability to purchase all DMRB and MCHW documents in the following formats from our online bookshop tsoshop.co.uk:

The website will continue to offer up-to-date information on all document amendments as and when they publish.

The yellow box at the top of the Home Page is where to look for details of upcoming and recent updates. The links to the actual documents will give you more detail on each.

The Standing Order service from Williams Lea TSO keeps you automatically up-to-date with new publishing as it publishes without the need for you to trawl the web for updates. You will automatically be sent a new CD or paper copies of the two complete, updated binders each time updates are made.

Help us to make future improvements to this service that benefit you by giving us your feedback in this four question survey.

Viewing files

Most of the documents available on this website are in the PDF format. You can access them by navigating through the different sections of the site.

Most of the section pages on the site are 'normal webpages' (HTML) and normally need no special software, whereas the 'parts' of the MCHW, DMRB or an IAN are available as PDF files and need special viewing software.

How do I know a link is to a PDF file?

In browsers with pictures enabled you will see a small icon in a link as in the following PDF icon example. This means that the link is to a PDF document: if you follow the link it will open a new window.

If your browser has pictures disabled, or if you are using a screen-reader, you will see text instead of an icon. The text will warn you that a link is to a PDF and that a new window will be opened if you follow it. This is shown in the PDF icon example here.

How to view PDF documents - Adobe Acrobat PDF reader

You can view PDF files using Adobe Reader software, which is available for many different computer systems including Windows, Macintosh, Linux and Palm. Visit the Adobe website to obtain the Adobe Reader software.
