Montreal road closures due to construction July 2026

Montreal-area drivers face significant road closures this July due to ongoing construction projects. The closures affect several major arteries, including portions of the Louis-Hippolyte-La Fontaine Tunnel. Authorities advise commuters to plan alternate routes and expect delays.

Major closures and affected areas

The Louis-Hippolyte-La Fontaine Tunnel, a key link between Montreal and the South Shore, will see lane reductions and periodic full closures overnight. Other affected routes include Highway 40, Highway 15, and several downtown streets. The construction is part of long-term infrastructure upgrades.

According to Transport Quebec, the work aims to improve safety and reduce congestion in the long term. However, short-term disruptions are unavoidable. Motorists are urged to use public transit or carpool when possible.

Timeline and duration

Closures began on July 1 and are expected to continue through August, with some projects extending into the fall. Specific closures are posted on the Transport Quebec website and updated daily. Drivers should check before heading out.

City officials emphasize that the construction is essential for maintaining aging infrastructure. The Louis-Hippolyte-La Fontaine Tunnel, opened in 1967, requires extensive repairs to meet modern standards.

Alternate routes and public transit

Authorities recommend using the Jacques Cartier Bridge or the Champlain Bridge as alternatives. Public transit options include the STM metro and bus lines, as well as the REM light rail system. Commuters are encouraged to allow extra travel time.

“We understand the inconvenience, but these upgrades are critical for safety,” said a Transport Quebec spokesperson. “We appreciate the public’s patience.”
