Extreme engineering

2010-07-06 00:00

CITY residents will know from the traffic disruption in the vicinity of Chota Motala Road and the N3 that something big is going on.

However, some are not aware of just how big the scale of the construction work is.

When the upgrading of the Chota Motala/N3 interchange is complete, Pietermaritzburg will boast a new big-city feature: a triple-decker interchange.

A complex set of multi-level roads will be built to carry traffic between Chota Motala Road and the N3. The new interchange should ease the traffic jams that are a twice-daily feature of the area.

During its construction, residents will be treated to the unfolding drama of engineering not unlike the projects featured on the TV programme about “extreme engineering”.

This will include the construction of new bridges over the N3 and Dorpspruit stream and the demolition of the old ones, plus the building of brand-new ramps on to and off the highway.

This complex project will be made all the more demanding by the need to keep traffic in the area flowing throughout construction.

The project manager of South African National Roads Agency Limited (Sanral), Gavin Harrison, said that there will be times when the area will need to be closed and cordoned off completely, but they will be limited to work that cannot be done without closure, like the launching of the new bridge over the highway. Closure will also be limited to two or three hours on Saturdays when necessary.

See page 9 for more information about the project.
