Feedback from Bakwena Platinum Corridor Concessionaire (Bakwena) confirms that the upgrades along the N4 Bakwena route are on track. Continuous maintenance, rehabilitation and upgrades are necessary to ensure the N1N4 route meets the highest international standards for toll road paying motorists.

The current upgrades include the addition of a 32km of a second carriageway on the N4 between the M17 and R512 (Brits Interchange). Part of this upgrade also includes additions and extensions to five existing bridges which cross the section of the N4 being dualled.

Recent developments include the dualling of the N4 bridge which crosses the Crocodile River. This bridge has five spans, each consisting of 10 precast reinforced concrete beams.

Each beam weights 26 tons and is individually transported via a process which involves a truck tractor on the one side and a steering trailer where a crane lifts each individual beam onto the bridge piers structure for it to be secured. The expected completion time for the dualling of the bridge is end of March 2020.

The various other upgrades along the Bakwena route are progressing well. Bakwena’s​ ​commercial​ ​manager,​ ​Solomon Kganyago,​ ​says​ the project cost of the current N4 upgrade is R582-million with a 36-month construction period that is scheduled to be completed in June 2021. The addition of the carriageway will ​enhance motorists’​ ​driving​ ​experience​ ​and​ ​improve​ ​their​ ​overall​ ​safety​ ​on​ ​the​ ​route, ​​concludes Kganyago.
