The Tanzania National Roads Agency ([[TANROADS]]) - an Executive Agency under the Ministry of Works, Transport and Communications - came into operation in July 2000 and is the agency responsible for the maintenance and development of the trunk and regional road network in Mainland Tanzania. The total classified road network in Mainland Tanzania was estimated to be {{convert|86,472|km}} based on the Road Act 2007. The Ministry of Works through TANROADS is managing the national road network of about {{convert|33,891|km}}, comprising {{convert|12,786|km}} of [[trunk road]] and {{convert|21,105|km}} of regional road. The remaining network of about {{convert|53,460|km}} of urban, district and feeder roads is under the responsibility of the Prime Minister's Office Regional Administration and Local Government (PMO-RALG).<ref name="Tanroads"/>

In 2007, there were {{convert|91049|km|mi}} of roads, of which including {{convert|6578|km|mi}} was paved. The road network ranked 51st worldwide by length.<ref>{{cite web| url = https://www.cia.gov/the-world-factbook/countries/tanzania/| title = "The World Factbook: Tanzania", United States Central Intelligence Agency, 10 July 2013}}</ref>

Trunk roads in Tanzania were marked by numbers following the two-tier number system with prefixes A- and B-, as is practiced in the rest of East Africa.<ref>{{Cite web|url=http://www.eac.int/infrastructure/index.php?option=com_docman&task=doc_download&gid=11&Itemid=70|title=East African Community Infrastructure|access-date=5 June 2016|url-status=dead|archive-url=https://web.archive.org/web/20160324092405/http://www.eac.int/infrastructure/index.php?option=com_docman&task=doc_download&gid=11&Itemid=70|archive-date=24 March 2016}}</ref> Following is the list of Tanzanian trunk roads.<ref>{{Cite web|url=http://tanroads.go.tz/uploads/documents/en/1444909370-Trunk%20n%20regional%20road%20map.pdf|title=TANROADS|access-date=5 June 2016}}</ref> Meanwhile, Tanzania has introduced a numbering system for trunk roads using numbers starting with "T"<ref>[http://open_jicareport.jica.go.jp/pdf/12150512_02.pdf Comprehensive Transport and Trade System Development Master Plan in the United Republic of Tanzania] (2011), Chapter 4 Road Sector, webpage Japan International Cooperation Agency - JICA</ref> but so far the "A" designations are visible if at all.

* Western regions are the most poorly served, with no paved highways except locally in [[Kigoma]] and [[Ujiji]]. Only one dirt road runs down the western side of the country, it is just a track between [[Kasulu]] and [[Sumbawanga]] and prone to flooding south of [[Mpanda]]. Between [[Tunduma]] in the south-west and Nyakanyazi junction near [[Kibondo]] in the north-west, a distance of nearly 1000&nbsp;km, there are no highways in the centre of the country.

===International highways===
[[File:Heading to Ngorongoro.jpg|thumb|right|Road heading towards [[Ngorongoro District|Ngorongoro]]]]
The [[Cairo-Cape Town Highway]], Highway 4 in the [[Trans-African Highway network]], runs between the northern town of [[Namanga]] on the [[Kenya]]n border and the [[Zambia]]n border town of [[Tunduma]] in the southwest, via [[Arusha]], [[Dodoma]], [[Iringa]], and [[Mbeya]]. The section between the entrance to [[Tarangire National Park]] and Iringa has been recently paved between Babati-Kondoa-Dodoma-Iringa. There is no longer a need to traverse a longer eastern route from Arusha to Iringa via [[Moshi, Tanzania|Moshi]] and [[Morogoro]] is paved. This route is {{convert|921|km|mi}} versus {{convert|689|km|mi}} for the Arusha-Dodoma-Iringa route.<ref name="distances"/>

In the southwest, from Iringa to Tunduma, the Cairo-Cape Town Highway follows the [[Tanzam Highway]] linking [[Zambia]] and [[Dar es Salaam]].
