As requested, this month we are doing one of the Northern Beaches routes that will disappear after the round of timetable changes later this month. The L88 operates between City Wynyard and Avalon via Spit Junction, Warringah Mall, Dee Why and Mona Vale in that direction only. Inbound services are instead listed as short workings of the L90.
The L88 runs every 30 minutes daily between 6am and 10pm, with higher frequency during evening peak hour. It operates using articulated 18m busses from Mona Vale and Brookvale depots.
