operation on 1 September 2019.\n3—Interpretation\nIn these regulations—\nAct means the Highways Act 1926;\ncommencement day means the day on which these regulations come into operation;\nProject means the Port River Expressway Project;\nrevoked regulations means the Highways (Port River Expressway Project) Regulations 2004 as in force immediately prior to the commencement of these regulations.\n4—Port River Expressway Project outline\n\t(1)\tParticulars of the principal features of the Project are contained in Schedule 1 as follows:\n\t(a)\tthe principal features of the Project that are ongoing on the commencement day are contained in Schedule 1 Part 1;\n\t(b)\tthe authorisations and declarations for the closure of roads and government railway lines under section 39G of the Act, and the obstruction of navigation under section 39H of the Act, for the implementation of the Project are contained in Schedule 1 Part 2.\n\t(2)\tThe particulars of the other principal features of the Project (being the features completed before the commencement day) are contained in Schedule 1 Parts 1 and 2 of the revoked regulations (other than clauses 5A and 9).\n\t(3)\tThe land to which the Project applies (including those aspects of the Project that are ongoing and the other aspects of the Project) is the area of land bounded by the bold black line connecting the coordinate points shown in Figures 2 to 5 in Schedule 2 of the revoked regulations.\n5—Responsibility for carrying out the Port River Expressway Project\nThe responsibility for carrying out the Project continues to be assigned to the Commissioner as the project authority.\nSchedule 1—Principal features of the Project\nPart 1—Principal features of the ongoing aspects of the Project\n1—Maintenance and operation of the road bridge named The Lieutenant Tom ‘Diver’ Derrick, VC, DCM Bridge\nMaintenance and operation of the road bridge across the Port River and its associated works will continue to be carried out (construction of the bridge and its associated works having been completed).\n2—Maintenance and operation of the rail bridge named The Saint Mary MacKillop Bridge\nMaintenance and operation of the rail bridge across the Port River and its associated works will continue to be carried out (construction of the bridge and its associated works having been completed).\nPart 2—Authorisations and declarations for closure of roads and government railway lines and obstruction of navigation\nDivision 1—Permanent closure of roads\n3—Permanent closure of roads\nPursuant to section 39G(1)(b) of the Act, the Commissioner is authorised to permanently close any road that it is necessary to permanently close for the purposes of implementing the Project.\nDivision 2—Permanent closure of government railway lines\n4—Permanent closure of particular government railway lines\n\t(1)\tPursuant to section 39G(2)(b) of the Act, for the purposes of implementing the Project, the Commissioner is authorised—\n\t(a)\tto permanently limit the use of the government railway lines listed in subregulation (2); or\n\t(b)\tto permanently close any or all of those government railway lines,\nas the case requires.\n\t(2)\tThe government railway lines are—\n\t(a)\tthe rail corridor between Francis Street and Eastern Parade, Port Adelaide; and\n\t(b)\t(following their transfer from the Australian Rail Track Corporation to the Crown)—\n\t(i)\tthe rail corridor between Signal 1456 (Glanville Station) and Signal 3 (Birkenhead); and\n\t(ii)\tthe rail corridor between Signal 14 (Gillman Junction) and Signal 1155 (Port Adelaide Junction).\nDivision 3—Permanent obstruction of navigation\n5—Permanent obstruction of navigation in Port River\nPursuant to section 39H(2) of the Act—\n\t(a)\tit is declared that the permanent obstruction of navigation over that area of the Port River bounded by bold black lines in Figures 2 and 3 in Schedule 2 of the revoked regulations (the delineated area) is necessary for the implementation of the Project; and\n\t(b)\taccordingly, the Commissioner is authorised to permanently obstruct navigation over the delineated area.\nSchedule 2—Revocation of Highways (Port River Expressway Project) Regulations 2004\nThe Highways (Port River Expressway Project) Regulations 2004 are revoked.\nLegislative history\nNotes\n\t•\tFor further information relating to the

The original regulations covered the entire Port River Expressway Project including construction phases, land acquisition, and extensive road closures. The 2019 version is a 'thin' replacement that only covers ongoing maintenance and operation of two completed bridges, plus residual closure powers. The construction-related provisions have been stripped out as the project moved from build phase to operational phase. This represents a deliberate shrinking of scope rather than expansion."},"complexity_factors":["Only 5 main regulations plus 2 schedules","Minimal defined terms (just 4: Act, commencement day, Project, revoked regulations)","Simple structure with no nested exceptions or conditional logic","Heavy reliance on external documents (Figures 2-5 in the revoked 2004 regulations) to define project boundaries","Straightforward revocation and replacement of earlier regulations","No penalty provisions, enforcement mechanisms, or dispute resolution procedures"],"plain_english_summary":"These regulations are a housekeeping update for a major road and rail project in Port Adelaide, South Australia.\n\n**What this does:**\n- **Replaces old regulations** from 2004 with a fresh 2019 version that reflects the current state of the Port River Expressway Project.\n- **Keeps two bridges running**: The road bridge named after war hero Lieutenant Tom 'Diver' Derrick, and the rail bridge named after Saint Mary MacKillop. Both bridges are already built; these rules just make sure someone keeps maintaining and operating them.\n- **Gives power to close roads and rail lines**: The Commissioner of Highways can permanently close roads and certain railway corridors if needed for the project. The specific rail corridors affected run through Port Adelaide, Glanville, Birkenhead, and Gillman areas.\n- **Allows blocking river navigation**: The Commissioner can permanently obstruct boat traffic in a specific area of the Port River where the bridges cross.\n\n**Who it affects:**\n- Drivers using the Port River Expressway and the Tom Derrick Bridge\n- Train operators using the Mary MacKillop rail bridge and surrounding rail corridors\n- Boats and ships navigating the Port River (restricted area)\n- Property owners and businesses near roads or rail lines that might be closed\n\n**Why it matters:**\nThis is essentially a \"project handover\" document. The major construction is done, so these regulations strip out all the old construction-phase powers and keep only what's needed for ongoing maintenance and operation. It also tidies up the legal authority to close certain roads and rail lines, and to keep the river navigation blocked where the bridges sit. Without these regulations, the legal basis for maintaining the bridges and managing the surrounding transport network would be unclear."},"summary":{"complexity_score":1,"scope_assessment":{"changed":false,"description":"Unable to assess whether the scope changed from original intent — no legislative content was available for analysis.
