The maximum speed limit on I-90 is in downtown Cleveland because of two sharp curves with a suggested limit of in a heavily congested area; I-70 through Wheeling, West Virginia, has a maximum speed limit of through the Wheeling Tunnel and most of downtown Wheeling; and I-68 has a maximum speed limit of through Cumberland, Maryland, because of multiple hazards including sharp curves and narrow lanes through the city.

On the other hand, Interstates 15, 80 and 84 in Utah have speed limits as high as within the Salt Lake City, Cedar City, and St. George areas, and I-25 in New Mexico within the Santa Fe and Las Vegas areas along with I-20 in Texas along Odessa and Midland and I-29 in North Dakota along the Grand Forks area have higher speed limits of .
