Plans have been unveiled for a new tunnel stretch in Sydney, Australia. The project is likely to cost US$1.98 billion (A$2.6 billion). This will involve building an underground extension to the F6 route in Sydney, providing a connection between the M5 and President Avenue. The new tolled link will be 4km long and is intended to reduce journey times for drivers, who will no longer have to pass through 23 sets of traffic lights. The project is also expected to reduce traffic volumes on General Holmes Drive.
