N01.08 MP-080166 - ENG Goulet Crissier - TP4 advance works 2026-27 (ID 11058)

This tender concerns anticipated works for the Goulet Crissier section, specifically focusing on the Maladière junction, scheduled for 2026-2027. The primary objectives are to ensure the safety of users and environmental compliance, while maintaining the optimal functionality of the road section. Key maintenance measures for the Maladière junction include geometric optimizations such as correcting entry and exit radii on the branches, reducing the width of circulation lanes within the roundabout, and adapting directional islands. Additionally, the surface water drainage system will be upgraded, involving the construction of a drainage trench along the central ring to replace the current impermeable surface, and the installation of a small pumping station. Maintenance of the existing superstructure is also included. Alongside these T/U maintenance measures, all underpasses will be renovated, including bringing curbs into compliance and replacing waterproofing. The works will be conducted under live traffic conditions, ensuring the continued operation of public transport powered by the contact line. The contact line will only be interrupted for a maximum of 4 weeks (weeks 29 to 32 of 2026) to allow for interventions on the underpasses located directly beneath the contact line's path. The project will span two years: 2026 will focus on underpass renovation and traffic phases 1 to 15, while 2027 will cover pavement maintenance and water drainage works, corresponding to traffic phases A to F. The roundabout experiences significant traffic volumes, estimated at approximately 18,000 vehicles per day.
