On June 9, the Luolu Expressway project undertaken by China MCC Group Co., Ltd. reported another success: with the smooth completion of substructure construction for the E1 ramp bridge at Dayang Interchange in Section 4, all substructure works for the 27 bridges in this section have been finished, marking a successful conclusion of the project's bridge foundation construction and pressing the "fast-forward" button for accelerated construction across the entire line.

The Luolu Expressway is approximately 97.5 km long, with the main line built to a two-way, four-lane expressway technical standard and a design speed of 120 km/h, linking Luocheng Mulao Autonomous County in Hechi City with Liucheng County and Luzhai County in Liuzhou City. The completed E1 ramp bridge is the connector between Dayang Interchange and County Road 073 (from Dayang Village to Luzhai North Station). The bridge is 157 m long and adopts a single-unit 5×30 m span design; the superstructure uses prestressed concrete post-tensioned simply supported-then-continuous T-beam construction, while the substructure abutments and piers use standardized column structures paired with pile foundation construction, effectively addressing the local complex geological environment and reinforcing the bridge's safety foundation.

During construction, the project department carried out refined and coordinated on-site management. On the basis of properly implementing forest land use coordination, it overcame multiple difficulties including complicated procedures, complex geological conditions, and stringent construction requirements, and completed all substructure works—including pile foundations, piers and abutments—to high standards in accordance with specifications, ensuring steady project progress. "As the last bridge in the section to undergo substructure construction, the project proactively engaged with local authorities in the early stage to coordinate forest land approval and land use matters, resolving the constraint of forest land use. We kept a close eye on schedule milestones, coordinated the allocation of labor, materials, and machinery, optimized the construction plan, linked up all procedures, and had the entire team seize favorable construction windows while strictly upholding safety and quality bottom lines, achieving completion on schedule," said Liu Jun, the project construction manager.

It is reported that 4 of the 8 ramps (including 5 bridges) at the Luzhai North Hub Interchange are already in use, connecting the Quannan and Yanglu expressways; all 4 ramps (including 4 bridges) at the Pingshan South Hub Interchange linking to the Yongliu Expressway have met traffic-opening conditions. All remaining bridges in the section have shifted to superstructure construction, with girder erection, bridge deck paving, traffic safety, and ancillary facility works proceeding in an orderly and steady manner. Once completed, the project will further densify the expressway network in central Guangxi, greatly stimulate the vitality of cultural tourism and logistics industries along the route, and inject lasting momentum into high-quality local economic and social development.
