In the neighbourhood where I live, there are eight blocks of flats in close proximity to the Central Expressway (CTE).

Residents have been exposed to noise and other pollutants for over 20 years. We are often woken up by noisy vehicles racing in the wee hours of the morning, interrupting our sleep.

It is also common to hear vehicles colliding, screeching tyres and sirens from ambulances when accidents occur.

I wrote to the Traffic Police to see if it was feasible to install a speed camera along this stretch of the CTE to curb speeding, thus possibly reducing noise, but I was told it was not.

I also wrote to the National Environment Agency almost a year ago to see if it could conduct a study on the effects of noise and air pollution on residents living along this stretch of the CTE, but I have not received a reply.

A study in Canada found that people living within 50m of high traffic roads have a 7 per cent higher chance of developing dementia than those living more than 200m away (Living near busy roads raises dementia risk; Jan 6). The block I live in is less than 5m from the highway.

I urge the authorities to conduct a similar study and find feasible solutions so we can have a healthier environment to live in.
