			Next to it is a similar assembly without the turn arrow. The byway logo panel appears above the NORTH direction plaque and a Route 58 marker, forming a simple vertical byway route assembly.
			To the right, two larger byway guide signs are shown. Both signs feature the Missouri Byway logo at the top and a white panel beneath it labeled “BYWAY NAME.” One version includes an additional blue supplemental sign below it reading “POINT OF INTEREST” with a right-pointing arrow. The final example shows only the byway logo panel above the “BYWAY NAME” panel, without a supplemental plaque.

On the opposite Route A approach from the right, a square guide sign with the letter A is mounted above a Lewis and Clark Trail plaque at the intersection.
			On the vertical road at the upper horizontal road (Route B), an assembly on one approach consists of a WEST plaque mounted above a Route 7 shield, which is mounted above a Lewis and Clark Trail plaque. Just past this Route B intersection, farther along the same vertical roadway, a second assembly appears with the same sequence of plaques: WEST mounted above a Route 7 shield mounted above a Lewis and Clark Trail plaque.
			On the opposite side of the vertical road, for traffic approaching from Route A in the opposite direction, two assemblies are shown in sequence: first, an EAST plaque mounted above a Route 7 shield and a Lewis and Clark Trail plaque, followed farther along by a second assembly consisting of a Lewis and Clark Trail plaque mounted above a right-turn arrow sign.\|'''Figure 903.4.50.2''' Standard Application of Trail Signing]]

The spacing between these signs follows the minimums indicated in the figure.
			On the east side of the roundabout, immediately after the northbound exit, either a directional assembly or an exit destination sign (D1-1e) may be installed. A similar placement pattern appears after the west exit and after the south exit, where each location shows either a directional assembly or an exit destination sign positioned just beyond the departure point. On the east exit specifically, a single exit destination sign (D1-1d) is shown without an alternative directional assembly.
			On the south approach, guide signing includes an advance route turn assembly placed before the roundabout entry, following a junction assembly farther downstream.

[[File:Figure 903.4.7 Examples of Uses of Abbreviations on Guide Signs.png\|thumb\|center\|alt=The figure includes three labeled sections demonstrating how abbreviations are used on guide signs. In the section titled “A. Cardinal Directions and Orientations,” two signs illustrate how cardinal directions and street name descriptors are treated. One sign reads “South Ave EAST,” showing that “South” is part of the street name and is not abbreviated, “EAST” is the direction of travel and is not abbreviated, and “Avenue” may be abbreviated. Another sign reads “S Randolphville Rd EAST,” showing that “South” as a pre-direction may be abbreviated, “EAST” is not abbreviated, and “Road” may be abbreviated when a standard form exists. In the section titled “B. Quadrant and Cardinal Directions,” the figure shows how quadrant orientations differ from full street names. A sign reading “SE Boulevard” demonstrates that “Southeast,” when used as a quadrant orientation, should be abbreviated, while “Boulevard” as the street name is not abbreviated. Another sign, “Southeast Blvd,” shows that when “Southeast” is the street name itself, it is not abbreviated, and “Boulevard” may be abbreviated. In the section titled “C. Other Descriptors Within Proper Names,” the figure shows examples of geographical feature descriptors. A sign reading “Avalanche Peak” indicates that “Peak,” as part of a proper name, is not abbreviated when no recognized abbreviation exists. Two additional signs, “Mount Olive” and “Mt Olive,” show that “Mount” may be abbreviated when a standard abbreviation exists.\|700px\|'''Figure 903.4.7''' Examples of Uses of Abbreviations on Guide Signs]]

On the left, a byway sign is mounted above a standard route assembly. The top panel displays the Missouri Byway logo with a stylized roadway, rolling green hills, and white flowers. Below it is a NORTH cardinal direction plaque, followed by a state route marker for Route 58, and a horizontal arrow plaque indicating a turn.
			Next to it is a similar assembly without the turn arrow. The byway logo panel appears above the NORTH direction plaque and a Route 58 marker, forming a simple vertical byway route assembly.
			To the right, two larger byway guide signs are shown. Both signs feature the Missouri Byway logo at the top and a white panel beneath it labeled “BYWAY NAME.” One version includes an additional blue supplemental sign below it reading “POINT OF INTEREST” with a right-pointing arrow. The final example shows only the byway logo panel above the “BYWAY NAME” panel, without a supplemental plaque. All guide sign examples are mounted on posts."\|'''Figure 903.4.50.1''' Examples of the Use of Missouri Scenic Byways Sign]]

The lower horizontal road is labeled Route A. On the Route A approach from the left, an assembly with a Lewis and Clark Trail plaque mounted above a left-turn arrow sign is shown at the intersection with the vertical road. On the opposite Route A approach from the right, a square guide sign with the letter A is mounted above a Lewis and Clark Trail plaque at the intersection.
			On the vertical road at the upper horizontal road (Route B), an assembly on one approach consists of a WEST plaque mounted above a Route 7 shield, which is mounted above a Lewis and Clark Trail plaque. Just past this Route B intersection, farther along the same vertical roadway, a second assembly appears with the same sequence of plaques: WEST mounted above a Route 7 shield mounted above a Lewis and Clark Trail plaque.
			On the opposite side of the vertical road, for traffic approaching from Route A in the opposite direction, two assemblies are shown in sequence: first, an EAST plaque mounted above a Route 7 shield and a Lewis and Clark Trail plaque, followed farther along by a second assembly consisting of a Lewis and Clark Trail plaque mounted above a right-turn arrow sign.\|'''Figure 903.4.50.2''' Standard Application of Trail Signing]]

On the north approach, a confirming assembly is placed on the right side of the roadway between 25 and 200 feet in advance of the roundabout entry, with an optional distance guide sign located farther upstream. The spacing between these signs follows the minimums indicated in the figure.
			On the east side of the roundabout, immediately after the northbound exit, either a directional assembly or an exit destination sign (D1-1e) may be installed. A similar placement pattern appears after the west exit and after the south exit, where each location shows either a directional assembly or an exit destination sign positioned just beyond the departure point. On the east exit specifically, a single exit destination sign (D1-1d) is shown without an alternative directional assembly.
			On the south approach, guide signing includes an advance route turn assembly placed before the roundabout entry, following a junction assembly farther downstream. Additional guide signage may appear on the approach side of the east leg as well, with spacing labeled to indicate minimum distances required for rural applications."
