The National Roads Authority is asking that people travelling along the Esterley Tibbetts Highway (ETH) do so with caution, now that they have begun repairing the sinking road.
During the initial construction process of the ETH, two different types of clearing and filling styles were implemented. The first was a traditional style, in which the NRA dug down to the bed rock and cleared away all the muck and debris. That style was implemented throughout the vast majority of the road. The second style is a Geo-Tech Style, that saw the NRA digging down to remove a significant amount of the muck and debris, however not all of the material is removed and large grid like structures were placed down then filled over.
The NRA says it was necessary to use the Geo-Tech style for areas that were developed at time, i.e. along the Strand shopping complex, and other areas in the surrounding vicinity.
However, the Geo-Tech Style has led to some sections of the road sinking over the years and now the NRA is trying to make a mends.
Work has begun on a cordoned off section of the road, and as of 4 March, the asphalt has been dug up from the inner lanes of both sides of the road. Therefore, drivers are now being asked to slow down.
However, construction on the road ways is not the only reason why drivers should be on the look out to apply their brakes. Speed limit changes are set to take effect as of Monday 7 March. A few signs have already been put up, however they were covered at air time.
