04 Where the name of the byway is to be displayed on identication signs or plaques along the byway route, the
name should be displayed in a Directional or Conrming assembly as follows (see Figure 2D-34):
A. On a Byway Identication (M10-2aP) plaque (see Section 2D.58) mounted below the M10-1 sign; or
B. On a Byway Identication (M10-2) sign (see Section 2D.58) with the M10-1aP plaque mounted below the sign.
05 In either case, the size of the National Scenic Byways (M10-1) sign, (M10-1aP) plaque, Byway Identication
(M10-2) sign, and Byway Identication (M10-2aP) plaque should be consistent with that specied for route signs
(see Section 2D.10) for the roadway classication.
06 Where the name of the byway is to be displayed along the byway route as provided in Paragraph 4 of this
Section, the byway Directional or Conrming assemblies should be located separately from any Route Sign
assemblies or Destination guide signs.
Standard:
07 When a National Scenic Byways sign is installed on a National Scenic Byway or an All-American Road,
the design shown for the M10-1 sign or M10-1aP plaque in Figure 2D-33 shall be used. Use of this design
shall be limited to routes that have been designated as a National Scenic Byway or All-American Road by
the U.S. Secretary of Transportation.
08 If used, the M10-1 sign or M10-1aP plaque shall be placed such that the highway route signs have
primary visibility for the road user.
09 The M10-1 sign or the M10-1aP plaque shall not be installed as sign panels on a guide sign or as part of
a guide sign assembly.
