Close to two miles of replacement sewer pipe are being installed under the east side of Milwaukee at a cost of nearly $30 million. The tunneling project will replace a deteriorated section of sewer with a new concrete sewer pipe. Soil variation and severe winter weather have affected the project, but so far the company has installed nearly 3,600 feet of pipe. A hydraulic excavator and lattice-boom crawler crane with clamshell bucket were used to dig the downshafts.
