Transport for Cape Town, the City of Cape Town’s transport authority, is working as quickly as possible to repair the section of Strandfontein Road that was damaged during the unexpected and extreme flood that happened on Sunday 1 November 2015. A City of Cape Town contractor was working on the downstream side of the culvert, preparing the section for the widening of Strandfontein Road, when unexpected and extreme weather conditions occurred on Sunday 1 November 2015. The flood undermined the bases of the culverts and subsequently the downstream section collapsed, forcing the City to close this section of Strandfontein Road.
Shortly thereafter, a professional team consisting of structural engineers from Transport for Cape Town and some consulting engineers investigated possible repair solutions, taking into account the anticipated widening of Strandfontein Road as well.
Since then, the collapsed culverts on the downstream side have been recovered and used on the upstream side to create a wide enough section for a bypass road. A concrete slab will be cast on top of the culverts to ensure stability and safety before the bypass road will be constructed on top of this structure. In addition, sheet piles will be used in the river, cutting off the flow of water under the existing structure. The voids under the bases of the existing structure will be filled with concrete.
The repairs to this section of Strandfontein Road commenced on Thursday 5 November 2015, and it is anticipated that work will be completed in the last week of November 2015 if all goes according to plan.
Traffic will be allowed on this section once the bypass has been completed and the road is safe again for road users.
‘I want to thank our residents for their patience and cooperation thus far while we are undertaking the repairs. We cannot allow any traffic on this section of Strandfontein Road until all of the repairs have been concluded and we are sure that the road is safe. Save to say we are working as fast as is practically possible as we know this is a very busy and important access route,’ said the City’s Mayoral Committee Member: Transport for Cape Town, Councillor Brett Herron.
