"It's the longest highway tunnel in Canada," he said.Planned work includes pavement, lighting, vaults, walls, signage and a fire protection system, as well as repaving of the highway between Boucherville and Montreal and necessary infrastructure for public transportation on highways linking to the tunnel.Champagne wouldn't say how the funding would be divided between the governments, so as not to compromise the tendering process set to open soon.He said it was important to announce the project to allow for preparatory work.Rouleau said about 13 per cent of the vehicles that use the tunnel daily are heavy trucks.She said the massive re-construction will cause some obstacles, but the province is planning mitigation measures including parking spots to encourage public transit use and lanes for buses and car pooling.There's also a consideration of a river shuttle between Montreal and its southern suburbs.There will also be an emphasis on communication with residents impacted by the work, Rouleau said.
