    Continuous Green T-Intersections

    TV at TVL-Continuous Green Tee option

    A Green “T” intersection, also referenced as Florida “T” or continuous green “T”. The crossroad left-turn movement from Tanque Verde Loop Rd would wave a dedicated auxiliary acceleration lane WB on Tanque Verde Rd separate from the WB through movement. This will facilitate left turn movements from Tanque Verde Loop Rd without stopping WB traffic on Tanque Verde Rd. The WB Tanque Verde Rd through movement would have a continuous green light.
