Line 6B Phase 2 Replacement Project

The Line 6B Phase 2 Replacement Project is replacing approximately 210 miles of its existing Line 6B crude oil pipeline in Indiana and Michigan. Enbridge Energy, Limited Partnership is replacing certain segments with new pipe, starting in Lake County, Ind., and continuing northeast to Marysville, Mich. Most of the new pipeline segments are being installed adjacent to existing segments.

This project is designed to meet both current and future pipeline transportation needs. Line 6B is an integral part of the region’s critical energy infrastructure, providing a safe and efficient supply of crude oil to numerous regional refineries in both the U.S. and Canada, which in turn supply the public’s need for refined petroleum products such as gasoline, diesel and asphalt.

The project provides a two-fold benefit and purpose:
  • Reduces the number of future maintenance activities
  • Restores the ultimate capacity of Line 6B to meet increasing demand along the pipeline route, which is largely driven by current and planned refinery upgrades and expansions in Michigan, Ohio and eastern Canada

Following the completion of this project in 2014, Enbridge will have replaced the entire length of Line 6B with new pipe from Griffith, Ind., to the St. Clair River in Marysville, Mich.

Overall cost of the project, including replacement of approximately 210 miles of pipeline and associated station and terminal facilities, is estimated at $1.3 billion for the Michigan portion and $300 million for the Indiana portion.

Information materials:

The project will generate additional property taxes in Indiana and Michigan communities and provide an influx of sales tax and local purchasing of materials and equipment. It is also creating more than 1,000 temporary and permanent jobs, including hundreds of skilled and labor workers during peak construction. Many workers are being drawn from the local workforce. Click here for more information about working on the Line 6B Phase 2 Replacement Project or providing vendor services.
