Second Durin Bridge fully “stitched”, to be fully completed by April next year

Monday, 16 December 2019, Sibu: Construction of the second Durin Bridge has reached another milestone when its last “stitching” process is now completed.

A symbolic ceremony to signify this last “stitching” process was performed by Works Minister, Yang Berhormat Baru Bian here yesterday.

The first “stitching” was carried out in early May this year where five out of 17 spans of this box girder bridge had to undergo the “stitching” process to close the segment in between two adjoining piers.

Four stages are involved in this “stitching” process where it started with installing and stressing the horizontal cross bracings before it is followed by adjusting the vertical alignment between the ends of the two opposing cantilever segments by using clamping trusses and carefully pulling them to match the level at the top.

Once this is done, it will be followed by installing the closing segment formwork to fix the closing segment in its rightful place, along with other necessary reinforcement after which it will be cast, using very high strength concrete, of the closing segment.  This will then be followed at last by the stressing of the bottom tendons of this closing segment upon the concrete maturing to the required strength.

With this last “stitching” in place, it means that the construction work on this 1.708km bridge is already at its tail end of construction with roadworks, streetlighting works and signages to be ensued soon after this.

The bridge, with construction cost of RM120mil, is expected to be fully completed two months ahead by April next year.

When completed, Durin Bridge will rise up to about 22m from the approach ground. It will mirror the existing bridge with two navigation channels.

The construction of this Durin Bridge, which started in July 2017 comes under Batang Rajang Section of Bintangor Junction- Julau Junction & Sibu Airport-Sungai Kua Bridge works package (Works Package 07). The other two Sections are Julau Section and Sibu Section. The main contractor is HSL DMIA JV Sdn Bhd.

Earlier, Baru said the people would be able to enjoy a more comfortable and efficient road network with the completion of the Pan Borneo Highway project.

“It will be a catalyst for Sarawak Corridor of Renewable Energy (SCORE) and development of potential areas, especially commercial and industrial centres along this highway,” he added.

Meanwhile, LBU Works Package 07 project manager, Liew Hin Leong said 32km of first carriageway under this works package are now completed up to the binder course layer and had already opened to traffic.

“While opening up the first carriageway, another 10km of second carriageway has also been completed up to binder course layer. The final layer will be the wearing course.

“The new 300m long Sibu Airport Interchange under this works package is seeing the construction of its flyover bridge deck progressing in earnest.  The piling works for the reinforced wall sections before and after the bridge proper are also progressing very well.  Once completed, the flyover will make road travel to and from Bintulu direction to Sibu Airport and Sibu Jaya a breeze,” he said during the event.

Overall, the Pan Borneo Highway Sarawak, from Sematan to Pujut Link Road in Miri, is expected to see about 400km of first carriageway nearing its completion and will be fully completed up to the binder course layer by year’s end where the traffic has already been shifted to majority of this carriageway.
