4.1 South Sudan Government Contact List

South Sudan has one of the world’s most underdeveloped roads networks. The total estimated track length in South Sudan is approximately 90,200km, which includes approximately 14,000 km of primary and secondary roads, and 6000km of tertiary tracks. The current interstate and international roads network consists of around 5,000km of gravel roads with approximately 300km of sealed roads. Currently only one international road, the 192km stretch between Juba-Nimule on the Ugandan border is sealed. The majority of other sealed roads are urban roads within the capital city Juba. All other national, interstate and urban roads consist of badly or non-maintained dirt roads.
The rugged land terrain, insecurity in certain areas along transport routes, the vast distances to be covered, and the sheer size of capital investment required, are all limiting the expansion of the roads network and addressing the severe infrastructural backlog currently faced by the government. The general infrastructure and conditions of the roads makes them vulnerable to seasonal influxes, with many roads impassable during the rainy season for extended period of times and cutting off large areas of the country.
All these factors contribute to relatively high transportation costs and the Government has identified the poor condition of the road network and infrastructure as one of the major constraints to economic and social development. As such, the government through its long-term development initiatives have identified road construction and the upgrade and expansion of existing infrastructure as a key priority.

Road Security

Since resumption of conflict in December 2013 road travel has become precarious. Road conditions, at best, remain assessed as very poor, markings and very limited maintenance increasing the security risk. Compounding this situation is the current absence of adequate policing of the nation’s roads, resulting in dangerous standards of driving and even in major towns there is almost no enforcement of existing traffic regulations.
During the rainy season, many of South Sudan’s roads become impassible and injury from motor vehicle accidents, and exposure to other risks such as illegal checkpoints to staff traveling by road increase. Road checkpoints are a common occurrence, especially in large towns and cities, and in areas that have recently experienced civil unrest.

Weighbridges and Axle Load Limits

Currently there are no weighbridges in the country and low capacity to enforce axle load limits.
South Sudan is adjusting to the regional axle load limits set through the Common Market for Eastern and Southern Africa (COMESA) and East African Community (EAC) requirements, and which is currently set at a maximum of 56 tonnes with a 0% weighbridge allowance. These requirements permit some of the highest Gross Vehicle Mass limits in the world; however, countries in the region apply these load limits differently so vehicles travelling through the region to South Sudan will be subject to compliance with the lowest axle load limit. Note, Traffic from Ethiopia into Upper Nile State can move payloads of 45MT per truck..
