What is it about ?
As part of the work on the Montmacq – Cambronne-lès-Ribécourt lock, spoil has been brought into the construction site area from the other side of the Thourotte Montmacq municipal road for several weeks. The number of dump trucks carrying this spoil is expected to increase significantly and requires the closure of rue Roger Martin (Montmacq bridge) and rue du Général Mangin (Thourotte side) from Monday, April 28, 2025.
ERRATUM: the closure of rue Roger Martin and rue du Général Mangin will ultimately not be effective no earlier than May 5 and no later than May 7, 2025*.
How long will the road be closed?
Between Thourotte and Montmacq, the Seine-Nord Europe Canal (CSNE) will be inserted between the Oise Lateral Canal and the Oise River. The two existing bridges will also be demolished and replaced by two new bridges, and a new bridge will be built to cross the CSNE. The bridge over the Oise will be the first to be demolished in 2026 while bridge over the Oise lateral canal will be demolished in 2027*.
For safety reasons, given the state of the current structures, the Thourotte-Montmacq municipal road will remain closed to vehicle traffic until the completion of the three new structures, i.e. by 2028*.

This stage consists of driving large steel sections into the ground by vibro-driving and then, in a second step, carrying out the piling to finalize their anchoring in their ground. If the vibratory driving is hardly perceptible, the driving of the sheet piles generates noise during its realization. It is however necessary to finalize the sinking of the sheet piles.
What is the duration* of the work?
The first sheet pile driving tests took place from March 22 and operations will continue until the end of March.
The work will take place from Monday to Friday from 8 a.m. to 18 p.m.
* Under adverse weather conditions and site hazards

What changes and for how long?
Construction hours will be extended from 6AM to 22PM over the following periods*:
Why are the hours extended?
The creation of this work consists in digging a micro tunnel (with a diameter of approximately 1m), passing under the future Canal Seine-Nord Europe to allow the watercourse of the Moulinet to join the new bed of the Oise. The micro-tunnelling machine – the machine used to build the tunnel – needs to operate over extended hours to progress because, in addition to digging the ground, it also lays the walls of the tunnel, thus making it possible to stabilize it. These operations must be carried out over long amplitudes.

What is it about ?
Work to rescinde the Oise along the RD66 began this summer and is entering a phase which requires the temporary interruption of all traffic between Montmacq and Cambronne-lès-Ribécourt to guarantee the safety of users and personnel working on the building site.
When will the county be cut off?
The RD 66 will be closed days and nights, from Monday November 28 to Friday December 2, 2022 included*. The companies managed to limit the road closure to just 1 week instead of the 4 announced. The bridges crossing the Oise and the side canal to the Oise will be inaccessible over the period.

Demolition of buildings
What works are carried out?
Construction of the Canal quays at Ribécourt-Dreslincourt and Pimprez is continuing and sheet pile driving will take place on both sites. This stage consists of driving large steel sections into the ground intended to retain the earth and serve as a support for the quay. The sheet pile wall also contributes to sealing the walls of the Canal.
What is the duration* of the work?
The driving of sheet piles on the 200 meters of linear quay at Pimprez and the 150 meters of quay at Ribécourt-Dreslincourt is planned between mid-February and mid-April 2022. Work will take place on weekdays and during the day only, Monday to Friday, between 8 a.m. and 18 p.m.
