## Data issues

Please see the [OS MasterMap Highways Network Known Data Issues page](/os-downloads/products/transport-network-portfolio/os-mastermap-highways-network-fundamentals/os-mastermap-highways-network-known-data-issues.md) for details of live and resolved data issues for the products.

We aim to publish a refreshed OS Open Roads Lookup table with OS MasterMap Highways Network – Roads and OS MasterMap Highways Network – RAMI orders twice a year, in line with OS Open Roads publication (April and October). 

**Due to unexpected delays, please be aware that the refreshed lookup table was not published with the October 2025 OS MasterMap Highways Network publication as planned and will also not be published in the November 2025 publication. A refreshed OS Open Roads Lookup table will be published as soon as possible and a further update will be provided in the December 2025 OS MasterMap Highways release note.**

## Product updates

As part of our forward scoping, we are currently reviewing the use of the Open Roads Lookup Table CSV included in the OS MasterMap Highways data packages (available in the *Resources* folder).

We are particularly interested in understanding how the link between Highways and Open Roads is being used in practice, and how widespread its adoption is.

If you actively use the lookup CSV and are happy to share your use cases or provide feedback, we’d love to hear from you. Please get in touch with the Networks Product Team at <networksproductteam@os.uk>.

## Next release

The next release of OS MasterMap Highways Network is scheduled for **December 2025**.
