The closure is part of the Gateway Expressway project which aims to construct two new tolled roadways that will provide direct connections between US 19 and I-275, and the Bayside Bridge (north of 49th Street N) and I-275.

Tr project will also widen I-275 to add a toll lane in each direction along the median next to the existing lanes from south of Gandy Boulevard to 4th Street North.

The project is estimated to cost $595 million and be completed by late 2023.
