Statewide Road Network including sealed and unsealed roads. The dataset represents navigable roads, including public and private access roads and tracks. A separate data layer stores 'unformed' DCDB centrelines which do not represent navigable roads. A limited number of associated features are stored separately as point features. Automatically updated when changes occur.

The State Maintained Roads dataset is derived from the TopoRoad dataset that is jointly maintained by DEWNR & DPTI. The Common Road Referencing System (CRRS) assigns a unique number to all roads of interest to Department for Planning,Transport and Infrastructure (DPTI) (currently or previously maintained) and defines the start, direction and end of the road for linear referencing (i.e. driven distance) purposes. The system defines reference points with known linear distances (known as road running distance). DPTI asset information is recorded in databases referenced using CRRS standards. This data set is for the Roads Maintained by the State or Federal Government.

Operators in the Road and Highway Construction industry in Mexico primarily engage in providing the supervision or construction of roads, transportation routes, bridges and steel and concrete signs and protections. These services include new jobs and extensions, as well as maintenance and repairs. Private companies are typically contracted to oversee and complete the construction process, while funding for these projects can come from various sources, with state and national government contributions accounting for the largest share. A significant portion of large infrastructure projects in Mexico are funded using bond issuances. Particularly for larger projects such as highways, a public-private-partnership (PPP) structure has been a popular method of funding in this industry. Consequently, construction companies often rely upon future revenues from tolls and other concessions and fees to cover the costs of construction. Mexico accounts for the second-largest network of limited access highways (toll roads) in both North and South America, after the United States, largely as a result of this particular funding structure that uses tolls to raise funding in lieu of fuel taxes.

Abstract This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied. Digital vector road centrelines for the Northern Territory. ## Purpose Contextual information for map production. The data set represents all known public roads in the Northern Territory and most private ones of significance. ## Dataset History Derived through the Northern Territory Government, Department of Lands, Planning and the Environment www.ntlis.nt.gov.au., as follows; The current dataset was established from the earlier DCDB which contained all the known public roads in the Northern Territory and other more used roads combined with the NT Pastoral Roads, the PSMA Indigenous Roads and the Geoscience Australia 1:250,000 Geodata Roads data sets in January 2007. The DCDB data is being continuously updated with new alignments and attributes from such sources as new Cadastre, GPS observations, new mapping and imagery and the Roads Information Mangement System.

Construction work on Europe’s extensive transport network is essential to keeping the continent moving. Maintaining and upgrading transport infrastructure in Europe typically falls on the government, with private contractors tendered to carry out necessary works. Strong investment to increase connectivity across the continent has supported construction order books in recent years, though inflationary pressures have threatened growth. Over the five years through 2025, revenue is slated to climb at a compound annual rate of 1.4% to €306.4 billion, including expected growth of 1.5% in the current year. The European Commission and other governments outside the trade bloc, including the UK, have directed significant investment towards transport infrastructure in recent years. Decarbonisation objectives have necessitated upgrades to outdated transport systems, while growing populations continue to cause wear and tear on the existing network, supporting demand for repair and maintenance work. Work on major projects, including HS2 in the UK and the Trans-European Transport Network (TEN-T), and ongoing funding for social infrastructure has limited the impact of volatile economic conditions. Inflationary pressures and economic instability – exacerbated by Russia’s invasion of Ukraine – have spurred a rise in costs and delayed projects. This disruption has stretched the cashflows of transport infrastructure contractors and caused governments to re-assess their transport infrastructure pipeline. Over the five years through 2030, revenue is forecast to climb at a compound annual rate of 5.7% to reach €404.7 billion. Ongoing repair and maintenance work will support demand across the industry in the coming years, while major multidisciplined contractors will continue to benefit from new orders as part of the EU’s TEN-T. Although recent inflationary pressures have spurred cuts to infrastructure pipelines, European governments remain committed to a number of major projects, including 134 transport projects laid out as part of €7 billion funding announced in 2024.
