Los Angeles County. This LRN was used for the future freeway routings of
Route 134 between present-day I-5 and I-210, and I-210 between Route 134
and Route 57, and Route 57 between I-210 and I-10. It duplicated the paths
of LRN 161 and LRN 9. The portion between the post-1998 Route 210/Route 57

Between San Dimas and US 60/US 70/US 99, LRN 240 was to have been
designated Route 71 (the signed Route 71 at this time ran to the east
along LRN 19).
