A very tall figure in Lewis County, Washington

Bigfoot sighting 12/27 at 12:30 a.m on I-5 during the winter storm. Hello, I’m trying to find other people who may have seen the same thing I did crossing the freeway in the middle of the night and middle of the snowstorm last night. There were about 3 or 4 other cars on the highway at the same time that would have seen this. I’ve never followed Bigfoot sightings or reported one before but this seemed like the best option to try and reach other folks. Seeing this thing really freaked me out. December 27 at 12:30 am during the winter snow storm I was driving home northbound to Seattle from Portland. Flights into SeaTac were all canceled and I managed to get a flight from San Diego to Portland and decided I would drive home because Alaska Airlines was telling me it might be two more days before flights were rescheduled. At 12:30 a.m. I was driving on I5 northbound through Centralia. After I saw this thing cross the highway I marked the location on Google Maps: (https://goo.gl/maps/nS15Gx3jcaVgdtPy9) but I was driving so give or take a couple thousand feet. It was 24 degrees outside, snowing, the roads were icy and snow packed, and it was dark, there were no street lights. There was a tall cement median separating northbound lands from southbound, I thought it looked a little taller than normal, maybe 4 feet. There was one truck about 100 yards ahead of me, nobody behind me that I can remember, and I think about 3 or 4 cars on the other side of the freeway coming southbound who all were close together and would have seen this thing like I did. On my right hand side (east side of freeway) was just dark forest for as far as I could see. Out my left window (west side of freeway) I saw a bunch of tall parking lot lights in the distance and what looked like a factory or warehouse a little ways maybe a thousand feet from the freeway. I was hyper-focused on the road because of the dangerous conditions and freezing temperatures, and driving about 40 mph. I saw directly in front of me what I thought was a black shadow floating westbound across the highway from the east side towards the median. As I got closer I was maybe 50-100 feet away and realized (or assumed) it was a person and I thought to myself what the hell are they doing? Crossing the highway in the middle of the night, in the middle of a freezing cold winter storm, and in the middle of nowhere…. I slowed down to not hit them. There were no cars stranded on the side of the road that I could see (I had seen a few during my drive), only dark forest, so who were they and where were they coming from I thought. For a second I thought they jumped out of the truck ahead of me but thought there’s no way it’s moving 40 mph like me. I then noticed the way it moved, it effortlessly crossed the cement wall. It didn’t even look like it jumped the wall, the whole traverse in front of me and across the median looked like it was gliding, or floating with an unusual ease. The way it moved really spooked me, but I saw it in my headlights enough to see it was a large humanoid form, and it was definitely not an optical illusion or floating debris like a trash bag full of styrofoam which I have seen in the past. As I squared up with it I had slowed down, and it was already on the other side of the median. I could see its silhouette with the distant parking lot lights backlighting it and I clearly saw the shape of a large head and shoulders and it looked like it was just walking at that point, literally just walking westbound across the other side of the freeway as about 3 or 4 cars were approaching it. I saw some brake lights and brights from those cars and think that someone of them must have also seen this. I was shook up honestly. The way this thing moved was ghostly and the way it cleared the median was surreal. And the shape of its head and shoulders looked just like what I’ve seen from Bigfoot imagery over the years, exactly the same. I drove back by the site my next day on my way to Oregon, during the day time, and confirmed that the cement median is a solid 5 foot high. Based on the head and shoulders that I saw after it crossed the median and stood up, I'm going to guess it was about 8 feet tall.
