Summary
Freestanding signs on property that directly abuts an interstate highway or its frontage road get the county's largest sign allowance: up to 225 square feet of sign face and 35 feet of height, the same ceiling reserved for roads posted 65 mph or faster, under Sign Ordinance § 19-55(b)(5)(E)(2).

(E) Special provisions.
1. A pole sign may be allowed should the sign be located on a road whose speed limit is fifty-five (55) mph or higher and the appropriate conditions are met.
2. Freestanding signs on properties directly abutting an interstate highway or a frontage road shall be allowed variances in height, square footage, and sign type in accordance with the 65+ mph provisions of the table above.
Full Breakdown
Business Use Area freestanding signs normally top out at 12 feet in height and an 80-square-foot sign face under § 19-55(b)(5)A, with sign copy limited to 80 percent of that face. A speed-based table in § 19-55(b)(5)D scales that allowance upward with the posted speed limit of the abutting road, from 90 square feet and 15 feet of height at 35 mph or less up to 225 square feet and 35 feet of height at 65-plus mph. § 19-55(b)(5)(E)(2) extends that top 65-plus mph tier, 225 square feet and 35 feet, specifically to freestanding signs on properties directly abutting an interstate highway or a frontage road, regardless of the road's own posted limit, allowing variances in height, square footage, and sign type.
A related special provision lets a pole-style sign, rather than the otherwise-required monument or pylon style, go up on any road posted 55 mph or higher. The county caps the allowance in the opposite direction on designated scenic corridors: § 19-55(b)(5)(E)(4) holds every freestanding sign on a scenic highway, including U.S. 25 north of Travelers Rest and U.S. 276 west of Cleveland, to the 35-mph dimensional standard of 90 square feet and 15 feet, no matter how fast traffic actually moves on that road.
Violations & Fines
The Codes Administrator enforces the sign size and height standards, including the interstate/frontage-road variance, under § 19-32(f). A first violation, such as a freeway-facing sign built beyond its allowed square footage or height, carries a civil penalty of up to $200 with seven days to correct it, and continuing violations are punishable at up to $2,000 per day, with the right to a hearing before the magistrate.
