The Oregon Department of Transportation is announcing a change with the speed limit signs on the Sunset Highway at the Highway 47 junction near Vernonia. ODOT says that new electronic speed limit signs have been installed, and they say that the speed limit will actually change, depending on the amount of traffic. State officials say that the speed limit on that stretch of highway will vary between 30 and 50 miles an hour, depending on traffic flows. They say that this change is intended to help traffic turning off of Highway 47 during times of heavy traffic flow, helping to make that a safer move. They say that this is an interim solution to the problem, with plans to install a new interchange at that junction in the future.
