Roads by 10: Defunct and Missing
Some three-digit numbers are not currently allocated to any road. These fall into two classes: defunct, where the number was previously allocated but fell into disuse, and missing, where (to the best of our knowledge) the number was never allocated at all. This page lists all the numbers currently thought by SABRE to be defunct or missing. If you spot a number on this page that you believe to be in use, or one that appears to be in the wrong list, please let us know here.
