TORONTO, Aug 27 (Reuters) - Enbridge Inc (ENB.TO) said on Wednesday it began construction on the Canadian portion of the C$3 billion ($2.9 billion) Alberta Clipper expansion project that, when up to full capacity, will enable it to ship up to 800,000 barrels a day of crude oil.
The company said construction began on the Alberta and Saskatchewan portions of the 1,607-kilometre (1,000-mile) pipeline.
The 36-inch diameter pipe, which will run from Hardisty, Alberta, to Superior, Wisconsin, is scheduled to be in service by mid-2010.
The line will have an initial capacity of 450,000 barrels a day and allow for expansions to increase capacity up to 800,000 bpd. ($1=$1.05 Canadian) (Reporting by Scott Anderson; editing by Rob Wilson)
