As you approach Corvallis from the south on 99W, after passing over the railroad tracks near Ricks Oil (west side) the posted speed limit is 35mph. At or very near the Highway 34 overpass the speed limit drops to 25mph. At this point you are passing beneath the overpass and 99W makes a fairly sharp turn to the right (north). Police park behind the overpass supports and cannot be seen until it is too late. Traffic commonly moves at 35-45mph in this area, as city streets do not start until just past the overpass. This is a well known area for traffic stings.
