The Line 61 Upgrade Project - Phase 1 involved increasing the capacity on Line 61 (referred to as Southern Access Project during its construction in 2007) between Enbridge’s Superior, Wis. Terminal and Flanagan Terminal near Pontiac, Ill. The Line 61 Project expands the capacity of the 42-inch pipeline from 400,000 bpd to 560,000 bpd.
The construction of Phase 1 Project was completed in the summer of 2014, allowing the 560,000 bpd capacity to begin flowing September 2014.
The Line 61 Upgrade Project - Phase 1 required the addition of pumping horsepower and crude oil tanks at or adjacent to existing sites and did not require pipeline construction outside station facilities. New pumping units, including all valves and accompanying equipment, were installed at pump stations in Superior and Vesper, Wis., and a new pump station was constructed adjacent to an existing Enbridge pump station near Sheldon, Wis. Modifications and upgrades were completed at Enbridge’s pump station in Delavan, Wis.
