Night work begins on Boulevard Berthelot

Night work on Boulevard Berthelot in Montpellier started on October 26, with periodic closures and a detour route. The City of Montpellier and Montpellier Méditerranée Métropole confirmed the schedule in a public announcement on October 21. The boulevard is located in the Croix-d'Argent neighborhood and is undergoing changes to improve tramway operations and reduce through traffic.

Work hours and access for residents

The construction work takes place from 10 p.m. to 6 a.m., from October 26 to October 30. The boulevard will be closed in sections as the work progresses. Residents will still be able to access their homes, as the Métropole has ensured that access for residents is maintained throughout the operation.

Markings removal and new road markings

The first two nights, from October 26 to 28, will focus on removing old road markings using hydro-abrasion, a technique that uses high-pressure water jets. New markings will be added during the nights of October 28 to 30. This process is detailed in the construction site plan published by the Métropole, which also outlines the detour route.

Detour route and temporary signage

The detour will use Avenue de la Liberté in both directions during the work. Drivers who usually pass through the area in the evening or early morning will need to follow temporary signs, with restrictions changing based on the sections being worked on. Daily traffic is not expected to be fully interrupted during the entire period.

One-way traffic and lane changes

On October 30, Boulevard Berthelot will have a lane reserved for motor vehicles traveling from Place du 8-Mai-1945 to Avenue de Maurin. The other lane will be for buses and cyclists. Motorists traveling in the opposite direction will need to permanently change their route. Bus routes remain unchanged, according to local authorities.

Traffic changes and tram line improvements

The reorganization comes ten months after the launch of tram line 5. By removing an automobile entrance at the intersection of Place du 8-Mai-1945, the Métropole aims to reduce disruptions to this line. The changes should also improve traffic for tram lines 2 and 4 at their intersection with Avenue de Maurin.

Objectives and cost of the project

The main goals are to improve the regularity and safety of public transport and reduce through traffic in an area shared by pedestrians, cyclists, cars, and trams. The boulevard had already seen traffic adjustments in December 2025, but the October 30 changes are definitive. The estimated cost of the construction is 60,000 euros, as reported by the City and L'Hérault Tribune. For residents and users, the two key dates to remember are the start of the night work on October 26 and the implementation of one-way traffic on October 30.
