Southern Expressway use up by two thirds since duplication

11 August 2015

More than 26,000 extra vehicles are using the Southern Expressway on weekdays since the duplication of the road.

Before the duplication, 39,690 vehicles were using the expressway on weekdays.

In the year since the two-way expressway was opened to the public, weekday usage has jumped to 66,130.

The bulk of the increase has been on city-bound trips, with the figure jumping from 20,164 before the duplication in 2010 to 35,210 this year.

Southbound trips have also gone up substantially, from 19,526 in 2010 to 30,920 this year.

Overall the amount of weekday trips has increased by more than 66 percent.

There has also been a significant decrease in traffic on arterial roads in the southern suburbs.

This is a good indication that the Southern Expressway is achieving its goal of drawing in vehicles travelling longer distances, in turn freeing up space on South Road for local traffic.

There has been a reduction of traffic on South Road near O’Halloran Hill with 45 percent fewer vehicles travelling on this road.

The $407 million Southern Expressway duplication project was opened last August and will link into the $620 million Darlington Upgrade, which is due to get underway late this year.
