The Mintlaw Viaduct is an abandoned steel and wooden railway trestle that was built over the Red Deer River by the Alberta Central Railway near Mintlaw, Alberta, in 1912. The last train to cross the bridge was in 1981, and the line and bridge was abandoned in 1983. The bridge is the second longest Canadian Pacific Railway bridge of its kind in Alberta. It is the longest and the highest bridge in Central Alberta. It is located west of Tuttle, northwest of Penhold, southwest of Red Deer, northwest of Red Deer Airport, and near the intersection of the C & E Trail and McKenzie Road.
