Today Wyo Speed Limit Up To 80
Starting today, we’ll be able to legally drive up to 80 mph on sections of interstate highways across Wyoming. WYDOT crews are changing speed limit signs along 3 sections of Interstate 25, three sections of I-80 and two sections of I-90.
Until the signs are changed, the posted speeds are in effect. The changeover starts today and should be finished by this 4th of July weekend.
Highway Patrol Administrator Col. John Butler says “The safety and welfare of the motoring public is a priority to the Wyoming Highway Patrol. The 80 mph speed limit will be strictly enforced. Drivers should not count on leniency if they operate at higher speeds.”
For now, the 80 mph speed limit will be introduced to:
I-25 • North of Cheyenne to south of Douglas; 117 miles (milepost 18-135);
• North of Douglas to south of Casper; 44 miles (mileposts 141-185); and
• North of Casper to south of Buffalo; 107 miles (mileposts 190-297).
I-80 • East end of Bridger Valley to west of Green River; 34 miles (mileposts 48-82);
• East of Rock Springs to west of Wamsutter; 55 miles (mileposts 110-165); and
• East of Cheyenne to west of Pine Bluffs; 27 miles (mileposts 373-400).
I-90 • East of Buffalo to west of Gillette; 64 miles (mileposts 59-123); and
• East of Gillette to between Moorcroft and Sundance; 40 miles (mileposts 130-170).
Under consideration for future speed increases are I-80 from west of Rawlins to just west of Walcott Junction, and I-90 from east of Sundance to the South Dakota state line.
