This upcoming Friday evening, a huge traffic alignment shift is scheduled to occur, weather permitting. All southbound lanes of I-275 between the I-4 junction and State Road 60 will be closed beginning at 11:30pm Friday night. Those lanes should begin to reopen, along the new alignment, around 5:30am.
During this time, all traffic will be detoured off I-275 SB and I-4 WB at the downtown exit ramps. Commuters will be directed to Kennedy Blvd, where they can reconnect to I-275 past WestShore Plaza, or any of the cross roads that intersect with the highway (Lois, Dale Mabry, or Howard/Armenia).
Alternatively, commuters from the north can use the Hillsborough Ave or MLK exits from SB I-275 to connect to Armenia or Dale Mabry. For those connecting to Lois, commuters can alternatively use the Floribraska exit, then connect to Columbus Dr via Tampa St. For those coming from I-4, commuters can either use Hillsborough Ave or connect to the Selmon toll road.
When the new alignment of SB I-275 opens up on Saturday, weather permitting, the new WestShore Blvd exit ramp will open, allowing HART Route 61LX outbound from downtown to resume routing.
