TxDOT Median

Medians are paved or landscaped areas in the middle of roadways that separate traffic traveling in opposite directions. Medians must present some sort of physical barrier to a driver. This usually takes the form of a raised curb, or grassy space between divided roadbeds. Paint lines do NOT count as a median. A roadbed is only considered to have a median if the total length of the median is longer than .1 miles (1/10 of a mile) before a major intersection or other significant break. A median with small breaks for left turns onto small side streets that don't have some sort of intersection control (and typically don't break the length of the median by more than 100 feet or so) is considered to be 'continuous'.
