Demolition of the century-old retaining wall on West Ludington Street in Iron Mountain began Monday morning. Here, Bacco Construction Co., which was awarded the work bid in February by the Iron Mountain City Council, removes sections of the rock wall that extends more than a block. Plans called for a precast concrete wall to be placed at the bottom of the existing wall and any portion above the 3-foot, 6-inch height of the new wall will be removed. (Ray King/Daily News photo)
