The tunnel is a short sighted expensive waste of space.
If they’re serious about building the tunnel they’ll build it from drummoyne to north sydney (or wherever). It takes an hour to go from the gladesville bridge to the iron cove bridge city bound on victoria rd in peak hour. This tunnel will do nothing to ease that logjam. And hence the delay to get to enter this 2nd harbour tunnel will remain. Who’s queuing up for an hour to get to this tunnel?
Geez I’m glad I left Sydney.
