These references are navigational aids positioned alongside roadways throughout the state. Every marker denotes the space, in miles, from a particular level, usually the state line or a serious junction. As an illustration, an indication displaying “I-10 Exit 203” signifies an exit on Interstate 10, 203 miles from the purpose of origin for that route.
The system gives essential location data for motorists, emergency companies, and transportation authorities. These references help in pinpointing accident areas, figuring out upkeep wants, and facilitating environment friendly navigation. Traditionally, these have developed from easy painted posts to reflective signage, incorporating GPS information for elevated accuracy and integration with digital mapping applied sciences.
