Safety Guidelines Determine How Roads are Cordoned Off

Media Replies 08 Nov 2013 road improvement works

We refer to Mr Ronnie Poon Beng Choon’s letter “Any guidelines on blocking roads” (Straits Times, 31 October).

Under the Street Works Regulations, utility agencies that need to carry out works on the roads are required to apply to LTA for a road works permit before their contractors are allowed to occupy the road for the road works.  The agencies and contractors are also required to comply with a set of guidelines to ensure road safety and proper traffic flow and control. 

As part of the guidelines, road works contractors are generally only allowed to close one lane to carry out works on the roads. In the event of a traffic build-up, the contractors are required to re-open the lane to alleviate any traffic congestion.

On the extent of the road to be cordoned off, there are guidelines to determine the safety distance required. For the safety of the motorists and workers, cones are placed upstream of the work area to prevent motorists from crashing into the work area.  The length of the cordon varies depending on the speed limit of the road with a longer distance required on a higher speed limit road. This is to allow sufficient distance for motorists to manoeuvre and merge safely with traffic on the adjacent lane.

We thank Mr Poon for the opportunity to clarify.
