Motorists were enjoying a faster ride on Monday following completion of the $40 million widening of Alfords Point Road.
There are now three lanes in each direction on the southern side of Alfords Point Bridge.
An extra southbund lane opened in June, and the project has been completed with a third lane on the northbound side of the road now available to motorists.
Completion of the work coincides with the start of new and extended clearways on the road corridor from Old Princes Highway at Kirrawee to Menai.
The road widening work, which began in April, 2017, was funded through the state government’s Gateway to the South pinch point program.
It overcomes a bottleneck which followed duplication of Alfords Point Bridge in 2008.
While the bridge provided six lanes of traffic, there were only two lanes of traffic on each side.
Alfords Point Road on the northern side of the bridge was widened to six lanes in 2011.
An environmental impact statement on widening the southern approach was released in 2013, and it has taken a further four years for the work to be done.
