MINISTER FOR URBAN SERVICES

LEGISLATIVE ASSEMBLY QUESTION

QUESTION No. 128

Road Intersection Treatments

Mr Westende - asked the minister for Urban Services:

(1) What is the Governments general view of the use of the Clover Leafy method of traffic management at the intersection of a main road with a freeway.

(2) What is the average cost of traffic lights.

(3) What is the average cost of roundabouts.

(4) Will the Government be considering the use of the Clover Leaf for the overpass at Weston Parkway and Dairy Flat Road intersection.

(5) Will the Government consider the use of the Clover Leaf, at the existing intersection of the Eastern Parkway and Hindmarsh Drive where considerable delays occur with the double traffic lights.

(6) Did the Government consider the use of roundabouts in Limestone Avenue bearing in mind the minor significance of most of the intersecting streets and the necessity to improve the flow of traffic on Limestone Avenue.

Mr Connolly - the answer to the Members question is as follows:

(1) Clover Leaf, intersections are very large, requiring a

considerable amount of land to construct, and

consequently they have a high capital cost. The

Governments policy is to provide intersection treatments

that provide an adequate level of service and good safety

at affordable costs.

(2) The capital costs involved in signalising an average intersection would amount to around $150,000 to $200,000, not including land costs.
