A spill that happened around 8 o'clock last night has resulted in a closure of the Fort Erie bound off ramp at Mountain Road in Niagara Falls.
The Ministry of Transportation confirming it was a tar spill.
They're estimating the closure will last until sometime this afternoon as the tar needs to set before they can clean it up.
Motorists wanting to exit at Mountain should use Glendale Rd or Thorold Stone Rd as alternates.
