The work was made up of 3 parts


1 - The Chemin de l'Argile Interchange

The planned roadway forms a direct link between the Rège tunnel and the Prado Carénage tunnel.
An interchange built on the new roadway connects to the surface network, namely the Chemin de l'Argile and the Avenue Arthur Scott.
The use of slip roads leading to the Rouet district is free.
This interchange opens up the Menpenti district by facilitating traffic flow to the Rouet, the Prado and city centre districts.

2 - The tunnel under the park

When the 26th Centenary Park was built, the Marseille Provence Métropole urban community carried out the large-scale work for the future 210m long tunnel under the gardens.
The SMTPC extended the structure by around another 55m under Avenue Cantini to allow vehicles to exit on the Prado side.
The tunnel has two lanes of traffic: one for each direction and only allows light vehicles less than 3.2m high and motorbikes.
The speed limit is 50km/h.
The SMTPC has put technical systems into place (security recesses, information boards, surveillance and communication systems, etc...) which are necessary for the motorist's security and comfort.

3 - Access from the Rue Louis Rège

Rue Louis Rège (between Rue du Rouet and Avenue Cantini) has been widened to match the Allées Turcat Méry: 2 lanes in each direction, wide pavements, new lighting...
This quality urban roadway also constitutes an easy, pleasant access route to the 26th Centenary Park.
The SMTPC undertook the necessary work for these adaptations as well as the access underpass to the new Rège tunnel.
