There are two bifurcations in the final alignment and seven CSO connecting structures/deaeration chambers and adits. The Lower Pogues Run Tunnel is a 10,200-ft, 20-ft, 2-in. bored tunnel with an 18-ft finished concrete lining, which bifurcates from the White River Tunnel alignment, and includes two CSO connecting structures/deaeration chambers and adits. The work is for Citizens Energy Group's DigIndy project, which is a CSO reduction program including six deep rock tunnels totaling over 28 miles. ommenced in September 2016 from a 35-ft diameter shaft that was previ- ously constructed as the retrieval shaft for the Deep Rock Tunnel Connector alignment. As of December 2017, mining of the White River Tunnel alignment extended approximately 4,800 ft, at which p d into the Lower Pogues Run Tunnel alignment, where it completed mining of the 10,200-foot alignment. As of December 2017, the contrac- ca- tion, and will then relaunch underground continuing on with the remainder of the White River Tunnel. Based on the terms of a federal consent decree, the White River and Lower Pogues Run tunnels must be operation- al by the end of 2021.

Work for this $27 million project for the City of St. Joseph Department of Public Works generally consists of the construction of 90-in. diameter concrete precast segment lined 6,648-ft long tunnel, 37-ft diameter baf- fle drop shaft, 48 ft of near surface reinforced concrete box culvert, 2-ft diameter vent shaft, 181 ft of 90-in. diameter open-cut steel pipe in- stallation, 125 ft of 90-in. jacked steel pipe, an energy dissipation structure, site restoration, and performance of other associated works. The proje - lization is continuing through the end of the winter. Super Excavators has installed steel sheeting for the energy dissipation shaft and began excavation. Secants for the tunneling launch shaft (48-ft diameter) have been in- stalled, and the shaft will be excavated in the coming weeks. The crew is currently setting up to begin a bore beneath existing rail road tracks which will ultimately act as the tail eing produced in China, and is in the final stages of manufac- turing as crews prepare f ected to arrive in the United States in early April 2018. Tunneling is expect- ed to commence in late spring 2018. It is the first EPB machine provided by Lovsuns in the United States. Black & Veatch is the designer. e to proceed was issued on July 17, 2017. Scheduled Completion is October 2019.
