To allow third parties to understand the extent, scope and timing of these road closures, we've created a data set of all the road closures that will be in place for this year's London Marathon. This has been created using an industry data exchange standard called DATEX II.
This is part of a pilot where we'll be trialling a different approach to releasing data, with the intention of helping developers make great products for drivers. Read about data usage for London Marathon on the TfL Digital Blog.
