Wyoming DOT installs variable speed limit signs on part of I-90

Electronic variable speed limit signs are now in operation along a segment of Interstate 90 in northeastern Wyoming.

The signs, installed near Piney Creek between Sheridan and Buffalo, will allow officials to reduce the speed limit in increments of five miles per hour to as low as 30 mph when necessary due to inclement weather. That stretch of I-90 is known for severe wind and surface conditions, WYDOT says.
