Pacific Motorway slowdown could be here for good

The Pacific Motorway slowdown, designed to ease congestion during the Commonwealth Games hasn't won drivers over - but like it or not, it could be here for good.

The state government hasn't ruled out keeping the 10kmh speed reductions, which began on March 1, but motoring groups don't agree it's the answer.

"We will of course look at the evidence and the data from this peroid of speed reduction," police minister Mark Ryan said.

The slowdowns, from 110kmh to 100kmh between the  Logan Motorway and Gaven and from 100kmh to 90kmh between Eight Mile Plans and the Logan interchange, are due to be lifted on April 17.

"It is important for us to ensure where there are ways we can do things better we look at those ways and then  of course we make decisions on how we can do that," Mr Ryan said.

The opposition has been quick to slam the a permanent reduction.

"People have travelled on this motorway at 110 kilometres an hour for years now and done it safely we don't see why it needs to be changed now," deputy opposition leader Tim Mander said.

Lauren Ritchie from the RACQ said variable speed limit signs could be the long-term answer.

"To be able to change the speeds according to the number of cars on the road is probably the best long term solution for that amount of traffic," Ms Ritchie said.
