WPC07 to see fewer temporary road diversions soon

Thursday, 9 January 2020, Sibu: Road users can expect more temporary road diversions along Bintangor Junction to Julau Junction and Sibu Airport to Sungai Kua Bridge stretch (Works Package 07) to be closed this year, leading to a smoother journey for all.

For Sibu Section, nine out of the current 33 active temporary road diversions on various locations are expected to be closed before the Chinese New Year celebration this January 25.

Another 22 diversions are expected to be closed four months later prior to Raya Gawai celebration at the end of May.

For Julau Section (length: 28.5km), travel would be even smoother as 25km of new carriageway has already been opened to traffic; the remaining road length will be opened by Chinese New Year.

Explaining the logic for the temporary road diversions, LBU project manager for Works Package 07, Liew Hin Leong said it is usually created away from the existing road alignment.

“That is why it is normally diverted from the travel line of the existing road.

“Since it is created away from the existing road, and normally being constrained within the right-of-way, it looks a little steeper and also looks more curved as it is supposed to be temporary anyway.

“The diversion will be demolished immediately once it is closed. We also have to allow drainage across it and that is the reason that a temporary culvert also has to be installed,” Liew said.

More often than not, Liew further explained that a temporary road diversion is created to construct a new culvert to replace the old ones at the existing road.

“In so doing, existing traffic will have to be diverted to the temporary road diversions.

“Due to various constraints, we can only construct half the culvert. In several cases, we even faced constraints where one line of culvert could only be constructed in three parts.

“That is why temporary road diversions are very important and crucial,” he added.

Liew said a temporary diversion is no longer needed when a new permanent carriageway has been completed and opened to traffic.

“Sometimes, the original existing road is reinstated and re-opened to traffic or another temporary diversion may be created on the existing road alignment or permanent alignment, but this is quite rare,” he said.
