Opinion No. 00-134
Application of the Building Height Restriction in the Scenic Highway System Act
QUESTION
Does the building height restriction in the Scenic Highway System Act of 1971 apply to that portion
of West End Avenue in Nashville that is a designated urban scenic highway?
OPINION
No. It is the opinion of this Office that the building height restriction in Tenn. Code Ann. § 54-17-
115, as amended, currently has no application to that portion of West End Avenue that is a designated
scenic highway. But because we also believe that the 1987 law amending the height restriction is
constitutionally suspect, a judicial decision declaring the amendment unconstitutional would leave the
previously enacted provisions of § 54-17-115(a)(1) in effect, so that a uniform building height limitation
would apply to all designated scenic highways, urban and rural.
ANALYSIS
The Scenic Highway System Act limits the size of buildings to be constructed along a designated
scenic highway to thirty-five feet. Tenn. Code Ann. § 54-17-115(a). In 1987, the legislature amended this
provision so that the height restriction applied “only to counties containing Class II rural roads as specified
in Section 54-17-114.” 1987 Tenn. Pub. Acts, ch. 30, § 2. As noted in earlier opinions issued by this
Office, this amendment, which was never codified, had the effect of applying the height restriction to all
designated scenic highways in counties containing Class II scenic rural roads, and not just to development
on scenic rural roads. Op. Tenn. Atty. Gen. 98-231 (Dec. 10, 1998); Informal Op. Tenn. Atty. Gen. (June
19, 2000). In other words, as long as the legislature has designated even a portion of a scenic rural road
within a county, the building height limitation would apply to construction along all scenic highways in that
county, whether they were designated urban or rural. But the restriction does not apply to development
along scenic highways in counties that do not contain Class II rural roads.

for those portions within the boundaries of incorporated municipalities." Tenn. Code Ann. § 54-17-
114(a)(2)(R). While we understand that a small segment of the Natchez Trace Parkway does lie within
the physical boundaries of Davidson County, we read the exception clause in subdivision (a)(2)(R) to
exempt this portion. This provision referencing the Natchez Trace Parkway was enacted in 1988, well
after the formation of the Metropolitan Government of Nashville and Davidson County in 1961. See 1988
Tenn. Pub. Acts ch. 694, § 1. The Tennessee Supreme Court has held that, once it is created, a
metropolitan government assumes the characteristics and liabilities of a municipal corporation.
Metropolitan Government v. Allen, 220 Tenn. 222, 231-232, 415 S.W.2d 632 (1967). Thus, there are

Under the current provisions of the Act, none of the Class II rural roads specified in Tenn. Code Ann. §
