Welcome to the Roadscapes Wednesday segment! Each week here on Geek Alabama, Roadscapes Wednesday will feature roads and infrastructure related topics. Geek Alabama Editor / Publisher Nathan Young is often called the “road geek” for a good reason, Nathan loves roads and loves talking about roads!
One interesting topic and aspect of freeway transportation is the system of exits used. There are the common ones, like diamond interchanges, which are used in most cases, especially in rural areas. Cloverleafs, which are used on rural interchanges between two freeways; stack interchanges, used in urban areas with high traffic; and several more, depending on where you are. There are so many unique designs and ways to get on and off of these large highways.
One of these unique cases are frontage roads. In most cases, these frontage or access roads move along the edge of freeways, providing more direct access to buildings and developments. This can be used conservatively or liberally, and one state that has an extensive system of frontage roads is Texas. In this state, nearly every mile of interstate and freeway comes with two frontage roads. Theres an extensive history that comes with this, which shows Texas’s interest planning history and what they find important.
