In 2025, MBL stuck "route number decals" to existing bus stop signs, masking the SoCal 511 phone line logo.
These decals are limited to the areas of Montebello and South San Gabriel.
Select stops in Montebello have been fitted with digital real-time arrival countdowns (in minutes) for each route served at the particular stop.
