The Fifth Ring Road
In association with Atkins, SSH was selected by the Ministry of Public Works to design and supervise the construction of the west section of the Fifth Ring Motorway.
The project comprised upgrading approximately 5.4 km to dual four lane motorway standard.
Particular attention was given to maintaining and protecting the heavy volumes of traffic on the ring road during construction. The work included the construction of two diamond type grade-separated interchanges built in an ‘island’ situation. The retaining walls of stabilised earth constructed at the interchanges totalled about 10,000 sqm.
