HOUSTON, TX -- TransCanada%20LOGO.jpg" style="width: 180px; float: left; height: 44px" />TransCanada says it's received approval from the Army Corp of Engineers to build an oil pipeline along the Texas Gulf Coast. The Canadian oil company has approval for a 115-mile portion of pipeline near Galveston, Texas. TransCanada is also awaiting federal approval for Keystone XL, a more ambitious plan to build a cross-border 1,700-mile pipeline to carry oil from Canada's Alberta region to Texas refineries. The proposal has hit several roadblocks, and the company is rerouting the line to avoid an environmentally sensitive area of Nebraska. If that is approved, the two pipelines will connect.
