DESIGN OF I-4 AND THONOTOSASSA ROAD
BES is improving the I-4 and Thonotosassa Road interchange by designing additional lanes on the ramps and approaches to the interchange. Project responsibilities include the installation of a traffic signal at the I-4 westbound ramps terminal intersection and the additional of another westbound left turn lane to create dual westbound left turn lanes. The existing northbound right turn lane at the I-4 eastbound ramp terminal intersection will be converted to a second northbound through lane. Other specifics include the addition of a right turn lane from northbound Thonotosassa Road (SR 566) to I-4 eastbound on-ramp and the widening of Thonotosassa Road (SR 566) from two lanes to four lanes between I-4 eastbound and I-4 westbound ramp terminal intersections. Signal timing coordination (cycle length and offsets) between traffic signals will also be provided.
