Florida State Road 516

State Road 516 (SR 516) is a proposed toll road by the Central Florida Expressway Authority (CFX). When constructed, it will serve an important transportation link between US Highway 27 (US 27) in Lake County and SR 429 in Orange County. It will also contain a full interchange with the planned County Road 455 (CR 455) extension providing access to nearby Schofield Road, and a partial interchange with Valencia Parkway featuring an eastbound exit and westbound entrance ramps. The proposed expressway would contain two 12 ft travel lanes in each direction, and two 12 ft shoulders on each side of the roadway in each direction. It also is planned to feature a recreational trail along the south side of the expressway that would extend from US 27 and ending its alignment with SR 516 at the CR 455 interchange. It also is going to be part of a pilot project with ASPIRE in pavement charging of electric vehicles. As part of construction, US 27 would slightly be shifted eastward in the area to avoid disruption to the Lake Louisa State Park on the western side of the roadway.

The first projects went to bid in late 2022. Construction is expected to begin in late 2023–2024 to open to the public sometime around 2027. It would serve as a capacity reliever to both SR 50 to the north and US 192 in the south.

During the CFX March board meeting, the timeline for the project was updated for groundbreaking of Segment 3 to be April 4, 2024 and for the construction teams for Segment 1 and 2 to be selected at the end of 2024.
