PT Wijaya Karya (Persero) Tbk (WIKA) continues to demonstrate its\ncommitment to supporting national strategic infrastructure development\nthrough the Semarang-Demak Toll Road project. The project is part of the\nTrans-Java Toll Network, playing a crucial role in enhancing\nconnectivity across Central Java\u2019s northern coastal region and\nfacilitating the movement of goods and people along the Pantura\ncorridor.<\/p>\n
Unlike typical toll road projects, the Semarang-Demak Toll Road is\ndesigned as a multifunctional infrastructure that not only supports\ntransport connectivity but also integrates as a sea dike. The project is\nexpected to help address tidal flooding issues in Semarang and\nsurrounding coastal areas, providing dual benefits as both a transport\ninfrastructure and a long-term flood control solution.<\/p>\n
As of May 2026, WIKA\u2019s progress on the Semarang-Demak Toll Road\nSection 1B has reached 83.39%. This includes key works such as main road\nconstruction, on and off ramps, elevated bridges, combi walls, and sand\nembankments over bamboo mats.<\/p>\n
In execution, WIKA has implemented specialised construction methods\ndue to the project\u2019s coastal location with soft soil characteristics\nposing significant technical challenges. A key element is the use of\ncombi walls, which form part of the sea dike structure and support the\ntoll road\u2019s embankment.<\/p>\n
The combi wall structure is designed to withstand combined soil and\nseawater pressure, including hydrostatic forces and potential ground\nsettlement. Thus, it plays a critical role in maintaining long-term\nstructural stability in coastal areas prone to tidal flooding.<\/p>\n
Additionally, the project employs sand embankments over bamboo mats\nas a ground reinforcement solution. This method ensures even load\ndistribution, enhances initial construction stability, and reduces the\nrisk of differential settlement in soft soil.<\/p>\n
WIKA Corporate Secretary Ngatemin stated that WIKA\u2019s involvement in\nthe Semarang-Demak Toll Road project reflects the company\u2019s role in\ndelivering infrastructure that addresses both mobility needs and\nenvironmental challenges in coastal areas.<\/p>\n
\u201cThe Semarang-Demak Toll Road is a strategic project with significant\nfunctions, not only as a new connectivity route in the Pantura corridor\nbut also as a tidal flood control infrastructure for coastal\ncommunities. Through this project, WIKA is committed to ensuring\nconstruction quality, workplace safety, and the application of methods\nsuited to the coastal region\u2019s characteristics. We hope the project will\ndeliver long-term benefits for the community, strengthen regional\nconnectivity, and drive economic growth in Central Java,\u201d Ngatemin\nsaid.<\/p>\n
Through the Semarang-Demak Toll Road project, WIKA reaffirms its role\nas a strategic government partner in delivering infrastructure that\nenhances connectivity while providing sustainable solutions to\nenvironmental challenges and community needs.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/integrated-tidal-flood-control-toll-road-in-central-java-nears-completion-1780148054", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
