The Freight Rail Revitalisation program helped to raise the quality of the major lines on the Tasmanian rail network through selective sleepering and track replacement. Culverts were strengthened, drainage and formation works undertaken and level crossings upgraded. These works built on upgrades under the previous Australian Government funded program that were designed to keep the lines at an operational standard, with the objective of improving overall safety, reliability and thereby competitiveness of the rail network. The Freight Rail Revitalisation program consists of two projects - one for Tasmanian rail lines on the National Land Transport Network (the Network), and one for those off the Network (Off-Network).
The project involved the upgrade and widening of South Road from Pym Street to approximately 100 metres south of the River Torrens, including a 4 km non-stop section of roadway (which incorporates a 3 kilometre section of lowered motorway) and the grade separation of two major arterial roads (Port Road and Grange Road). Work also included an overpass of the Outer Harbor rail line and improved cycling and pedestrian facilities.
The project involves the upgrade of the Boundary Road Interchange approximately 30km north of the Brisbane CBD and will include a new six lane, four span concrete bridge over the Bruce Highway.
The area adjacent to the existing airport access currently creates dust and drainage issues from the unsealed areas. The roadway is currently used as an informal car park for on-street parking, however is not currently wide enough, with parked vehicles often extending into the road carriageway creating a safety hazard.Widening of the road/seal including linemarking to delineate the on-street parking bays. Concrete kerb and channel (layback) or a concrete invert drain will be required to support the edge of seal. This will reduce dust, improve safety by defining the on-street parking arrangements and improve drainage.
The road has a damaged existing seal with road base and sub-base deterioration facilitating minor drainage repairs.Initially accomplish minor drainage repairs as needed followed by required base and sub-base layer stabilisation where required. Bitumen re-sealing is completed to protect the road base and improve road surface.
