M2 Widening Will Slow Buses

An article in the Sydney Morning Herald brings attention to the consequence of removing the bus ramp at Epping, which is part of the M2 widening project.
The ramp is used by 60 bus services a day, transporting 17,000 passengers a day down the bus lane of the M2 into Epping, from where trains can take them on to the City (via Macquarie Park), south to Strathfield and the south and west, and up north to Hornsby.
The ramp also enables those buses to turn around quickly at Epping and go back to fetch more passengers.
The M2 project proposes to demolish the ramp and require buses to stay on the motorway to Macquarie.
Those buses will then, presumably, have to fight the traffic on blocked roads to drop passengers anywhere near the train station entrances. Not only will this delay passengers, it will also greatly reduce the availability of buses for the high speed runs up and down the motorway.
The article quotes a local traffic engineer as saying "removing this ramp will cause major delays that could result in the cutting of services."
The HillsM2 website says "The Hills M2 is a key public transport corridor. The motorway includes dedicated bus lanes with 435 Hillsbus services using the motorway week days (eastbound and westbound), carrying over 17,000 passengers a day." The website doesn't comment on the number of those who will have to revert to using their cars on the M2 and other main roads when they can't get off the bus and onto trains at Epping!
