New electronic variable speed limit signs are now in operation on Wyoming Highway 28 in the South Pass area between Farson and Lander. The signs will allow the Wyoming Department of Transportation to drop the speed limit in 5 mph increments to as low as 30 mph when weather and road conditions make it necessary. The 34-mile section of the highway is known for severe wind and surface conditions as well as heavy truck traffic. The South Pass section becomes the fifth Wyoming highway section to be served by variable speed limit technology. The other four sections are on I-80, where 128 miles are equipped with variable signs.
