Historical Evolution

The “End of Divided Highway” sign has undergone significant evolution over time, reflecting changes in traffic patterns, road design, and regulations.Initially, the sign was a simple rectangular sign with the words “End Divided Highway” in black letters on a yellow background.

This design was used from the early days of divided highways in the 1930s and 1940s.In the 1950s, the sign was standardized and incorporated into the Manual on Uniform Traffic Control Devices (MUTCD), which established national standards for traffic signs and signals.

The MUTCD specified the sign’s shape, size, and color, and required it to be placed at the end of divided highways.Over time, the sign’s design has evolved to improve its visibility and effectiveness. In the 1970s, the sign’s background color was changed from yellow to fluorescent yellow-green, which is more visible in low-light conditions.

The sign’s shape was also modified to include a triangular shape, which helps to draw attention to the sign.In addition to changes in design, the sign’s placement has also evolved over time. In the early days of divided highways, the sign was typically placed at the physical end of the divided highway.

However, as traffic patterns changed and highways were extended, the sign was often placed at the end of the divided section, even if the highway continued as a non-divided road.The regulations governing the use of the “End of Divided Highway” sign have also changed over time.

In the past, the sign was only required at the end of divided highways. However, in recent years, the MUTCD has been revised to require the sign at the end of any divided section of a highway, regardless of the length of the section.
