Line 234 (Sepulveda Blvd.)
- Proposed for extension via modified Line 183 alignment between Sherman Oaks and Burbank. Never implemented; Line 234 interlined with Line 183 as part of Metro Red Line Bus/Rail Interface June 24, 2000.
- Proposed to be replaced by new Line 632 "smart shuttle" between Sylmar/San Fernando Metrolink Station and Mission College. Never implemented due to ongoing logistics problems with (and later cancellation of) LADOT Smart Shuttle.
