The city of Tampa, Fla., is consdering a public-private partnership that would create an 8.25-mile, 18-station streetcar connection between downtown and the city’s airport. Proposed by Australia-based infrastructure developer Plenary Group, the system would cost as much as $700 million to build, depending on the type of transit technology used. A decision on whether to pursue the proposal may hinge on when and how the Florida Supreme Court rules on a challenge to a 2018 local transportation sales tax referendum, which passed with 57% of the vote. Tampa recently received $67.3 million in state funding to expand and modernize its existing 2.7-mile downtown streetcar system.
