Tunis is Tunisia's largest city as well as its capital, with a population of more than 2 million. The greater metropolitan area holds some 2.5 million inhabitants. Situated on a large Mediterranean Sea gulf behind the Lake of Tunis and the port of La Goulette, the city extends along the coastal plain and the hills that surround it.

Tunisia`s economic rise

Despite the boisterous and active trade going on in the medina (a dense agglomeration of alleys and covered passages, full of intense scents and colors, at the center of the city), the expansion of the Tunisian economy in recent decades is reflected in the booming development of the outer city where one can see clearly the social challenges brought about by rapid modernization in Tunisia.

Tunis stressed by traffic

The Greater Tunis region is divided into southern and northern areas by the Lake of Tunis Canal. Traffic between the two areas depends either on routes passing through the urban area of Tunis or ferryboats connecting the two biggest ports. The ferryboats, however, are limited in terms of service, frequency and capacity, and most of the south-north traffic concentrates on the routes passing through the urban area of Tunis, causing traffic congestion and environmental deterioration in the city.

National development plan

The future traffic volume will need to be reduced as economic activity and tourism increase. Road-related projects based on a National Development Plan are aimed at mitigating traffic congestion in this area. The La Goulette Bridge project is considered an important link connecting the south-east and north-west areas of the metropolitan area and is the first of its kind in Tunisia, and indeed anywhere in the African continent.

Concrete for the cable-stayed bridge

Sika Tunisia supplied concrete and superplasticizers for the project during the entire construction period. The concrete structure of the 260-meter-long cable-stayed bridge is divided into three spans measuring 70, 120 and 70 meters respectively. The bridge deck, located 20 meters above sea level, is held by two 45-meter-high pylons. 23.5 meters wide, it is divided into two channels, two emergency lanes, and a backfill. The bridge definitely provides genuine relief from traffic jams!
