The Washington State Department of Transportation has reopened Highway 14 near Salmon Falls Road between Washougal and Stevenson.  The road had been closed since Tuesday morning for cleanup work where a tractor-trailer hauling two tankers of hot oil crashed and spilled about 3,000 gallons of oil.  The oil is used in asphalt for road construction and becomes sticky when cooled.  Before the highway could be reopened, crews had to grind down and repave portions of the highway.  The road will still only have one lane open, alternating directions for several days.  According to the Washington State Patrol, the driver approached a curve when the rear tanker began to drift.  The driver then overcorrected and hit a guardrail.
