New Epping to Thornleigh Third Track rail bridge over M2


Construction of a new rail bridge over the M2 starts next weekend as part of a major project to improve train reliability in northern Sydney.

Installation of a pier for the new bridge for the Epping to Thornleigh Third Track (ETTT) will mean motorists and M2 bus customers should allow some extra travel time or consider alternative routes this weekend.

ETTT is one of four Northern Sydney Freight Corridor projects being delivered to improve reliability for passenger services and freight services.

The projects at North Strathfield, Epping to Thornleigh and Gosford will separate passenger and freight train services at key points in northern Sydney and the Central Coast, delivering greater reliability for Sydney Trains and NSW TrainLink Intercity customers, and include upgrades of several northern Sydney train stations.

There will be diversions, lane closures and a reduced speed limit of 40km/h around the construction area while work is undertaken from 9pm on Saturday 7 February to 5am on Monday 9 February.

On ramp closures will be in place at:

  • Citybound Beecroft Road, 9pm Saturday to 5am Monday.
  • Citybound Pennant Hills Road, 8am to 7pm Sunday.
  • Windsor Road, implemented as necessary.

​For more information about traffic conditions during these closures, visit the Live traffic website Image removed. or phone 132 701.

There will be no changes to bus stops and routes, but please allow extra travel time. To plan your trip, bus customers can visit or call 131 500.

In case of wet weather, construction will move to the following weekend: Saturday 14 February to Monday 16 February. Further work on the new bridge will be completed at a later date.
