Colonial Pipeline constructed its mainline through Virginia in 1964. The company also built a spur from Mitchell Junction Tank Farm in Cumberland County to Montvale in Bedford County. The spur, called Line 25, delivered refined petroleum products such as diesel, gasoline, and home heating oil.
Line 25 stopped at the Montvale tank farm, 16 miles east of Roanoke. The pipeline company evidently concluded in 1964 that it was cost-effective to build to a site near Roanoke, but better to avoid construction across the entire Blue Ridge.

A booster pump at Lynchburg segmented the pipeline. The maximum allowable operating pressure between Lynchburg-Roanoke (1440 pounds per square inch gauge pressure) was slightly higher than the pressure between Mitchell-Lynchburg (1305 pounds per square inch gauge pressure).1

The line transported one million barrels of refined products each month. Along the way, it served five separate terminals from which fuel trucks delivered petroleum products to customers.
Colonial Pipeline announced in 2017 that it would shut down Line 25, rather than spend the money required to repair almost 80 miles of pipeline. Colonial Pipeline gave the owners of the terminals a year's advance notice. That provided time to find alternative locations to load distribution trucks before the pipeline shutdown in 2018.2
Closing Line 25 meant that the businesses which had been using it, and ultimately their customers, would incur higher costs. Petroleum products will remain available, but tanker trucks will be required to drive a longer distance to Greensboro or potentially Richmond. The Virginia Petroleum, Convenience and Grocery Association estimated that prices at area gas stations would increase three to six cents per gallon, and add 170 additional tanker trips per day on the roads after the line closed.3
Colonial Pipeline calculated it would cost $200-300 million to repair Line 25. Closing that spur did not mean Colonial Pipeline would automatically lose business. The competing Plantation Pipeline spur to Roanoke was already near capacity. The tanker trucks that used to load up at Montvale may still end up using petroleum products transported by Colonial Pipeline, but drive further to Greensboro or Richmond.4
Closing a pipeline does not equate to total abandonment or removal of the pipe. Colonial announced it would drain the pipe, then fill it with an inert gas to prevent fumes from creating any explosion hazard. The company will also continue to mow grass and maintain the right-of-way, rather than allow it to revert to forest.5
Closing Line 25 eliminated 20 jobs at the Montvale, Virginia tank farm. Offsetting that impact was the need to hire more truck drivers to transport refined petroleum products from Greensboro.6

One alternative to trucking gasoline and home heating oil from Greensboro was delivery via Norfolk Southern railroad by rail car to Roanoke. There is a terminal located on that railroad where tanker cars could deliver to storage tanks. KinderMorgan, owner of the Plantation Pipeline, has a terminal east of downtown Roanoke next to the Tinker Creek waste transfer station.
In 2021, the Bedford County Board of Supervisors asked for state assistance in studying how petroleum products could be delivered by rail to the tank farm at Montvale.7
one alternative to Line 25 is to ship petroleum products to KinderMorgan's terminal by rail
