Nope. The I-15 truck lanes have a centerline more or less the same as the mainline's. Ditto I-5/99 southern interchange, and the I-10 bus lanes. The I-5/405 southern interchange has separate roadways for truck and carpool lanes, all of which share centerlines with mainline I-5 or I-405 as applicable. If we were to try to map the truck/car/bus lanes as separate routes, they would all follow the mainlines' alignments, and would not show up in Mapview, etc. as separate, so no point to that exercise.
By contrast, I-5 Truck in Newhall has a different centerline from I-5's, and indeed the truck lanes in both directions are mostly east of both the main lanes' roadways. The Newhall truck route is a part of former US 99, bypassed by the new freeway.
