Continuous Flow Intersections

In a Continuous Flow Intersection (CFI), vehicles that intend to turn left cross to the left side of the roadway before they enter the intersection at a separate traffic signal. This eliminates the need for separate left turn signals at the intersection. Benefits include improved:

• ​Safety
• Mobility
• Connectivity
• Frontage road traffic flow​

A CFI is already in use within the corridor at I-35 and Loop 82 (Aquarena Springs Drive) in San Marcos. Construction is underway for another CFI located at I-35 and SH 80 (Hopkins Street) in San Marcos.
