## Data issues

## OS Open Roads lookup table

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delays, please be aware that the refreshed lookup table will not be published with the\
April 2026 OS MasterMap Highways Network publication as planned. A refreshed OS Open\
Roads lookup table will be published as soon as possible and a further update will be\
provided in the May 2026 OS MasterMap Highways release note.

## Next release

The next release of OS MasterMap Highways Network is scheduled for **May 2026**.
