Bossier City, LA Sign Regulations: Freeway-Facing Signs (2026)

Section 8.3.2 of the Unified Development Code sets the general height ceiling for on-premises advertising signs at the maximum building height of the zoning district or 45 feet, whichever is less, with height measured from ground level at the sign's supports to its highest point. Subsection B carves out a specific, much taller allowance for signs oriented toward an interstate highway or a raised expressway. A sign qualifies for the taller standard only if it sits on property no farther than 400 feet from the nearest point of the interstate or expressway right-of-way.

Qualifying signs can rise to 75 feet, or to 25 feet above the centerline of the raised expressway itself, whichever comes out taller, a formula written for signs near the elevated interchange sections that cut through Bossier City. The code is explicit that the 400-foot distance is measured in a straight line from the nearest part of the sign face to the nearest right-of-way point, without regard to any building or structure standing between them. The area bonus is just as generous as the height bonus: an interstate-facing sign is allowed twice the square footage that Section 8.3.1 permits for an ordinary freestanding sign on the same size lot, recognizing that a sign meant to be read from a moving vehicle at highway speed needs to be both taller and larger than a sign aimed at pedestrians or slow local traffic.

These freeway signs still have to comply with the general structural, safety, and illumination standards of Section 8.3.3, including the citywide setback of at least 5 feet from any property line, and Section 9.6's separate height limits govern off-premises billboards rather than these on-premises signs.
