Roadway Signage Types
Roadway signage addresses two primary signage needs along the roadways of historic Texas highways. The two sign types are: route identification signs and advance/directional signs.
Route Identification Signs
Route Identification signs are to be placed along the historic alignment to bring attention to the beginning and end of historic routes. Route identification signs principally identify road alignments along the length of the historic Texas highway that has been designated as historic.
Advance and Directional Signs
Advance and Directional signs are meant to guide visitors to and from the current roadway to the historic road corridors. Directional signs are placed to notify the motorist of turns within the historic route or provide advance notice of a historic route. Basic directional sign variations include the addition of left- and right-facing arrows, as well as simple mileage indicators to guide visitors at major crossings and critical junctions along the historic Texas highway route.
Design of Roadway Signs
All route identification and directional signs must follow TxDOT signage specifications. All text and backgrounds for Historic Texas Highway signs must be retroreflective with a white message, brown background, and 1-inch white border (with a 3-inch radius at the corners). The sign must feature 4-inch letters using Clearview font.
The width of the sign should not exceed 48 inches. The height of the sign will vary based on the size of the message. Text must be limited to five lines for ease of readability by motorists.
Highway logos and symbols (other than arrows) are not permitted per TxDOT specifications,
except for Route 66 in order to maintain uniformity with signs that are currently installed on Route 66 in six other states.
