According to this short story in the San Bernardino County Sun, a new California Welcome Center on Hospitality Lane near the junction of Interstates 215 and 10 will have a Mother Road flavor when it opens in February:
The California Welcome Center will combine a Route 66 and 1950s retro theme with plasma screens, multimedia, and kiosks linked to local Web sites, along with wireless Internet access.
California might have gotten the idea from Texas and this rest area.
