The Main Street Tunnel, located in Welland, Ontario, Canada, is an underwater tunnel, carrying Niagara Regional Road 27 and the unsigned designation of Highway 7146 (East Main Street) under the Welland Canal.
The tunnel links Highway 406 on the east side of the canal to Highway 140 on the east side. It is also the primary access route to downtown Welland for Cooks Mills residents who are separated by the canal. On a bigger scale, the Regional Road 27 provides a connection from Welland to Niagara Falls.
The structure was built as a part of the Welland By-Pass project. Its construction was made easier because, like the Townline Tunnel, it was being built at the same time as the channel above it. In contrast, the Thorold Tunnel had to be dug underneath the existing waterway. The construction cost $13 million. Official opening was on May 20, 1972.
The tunnel provides four lanes for traffic, two in each direction, separated by a full-height concrete wall. There is also a sidewalk for pedestrian use in the westbound section.
