$2.8 billion transportation upgrade rolling

By Lou Ortiz

The Transportation Improvement Program for Miami-Dade County has scores of projects on the drawing board over the next five years — with some already underway — and a budget of $2.8 billion. The Transportation Improvement Program, known as TIP, is prepared by the county's Metropolitan Planning Organization (MPO) in cooperation with other transportation agencies including the Florida Department of Transportation District 6, the county's Expressway Authority, Aviation Department, Transit Agency and Seaport, along with the South Florida Regional Transportation Authority and Florida Turnpike Enterprise. District 6 also includes Monroe County.

The 2013 fiscal year for the program began July 1 and ends June 30, 2013. The five-year plan runs through fiscal 2017, which ends June 30, 2017.
The $2.8 billion budget includes $2.120 billion for improvement projects for highways, bridges, transit, aviation, rail, seaport, freight and bicycle paths. It also includes the cost of buying land for rights of way, resurfacing improvements and safety programs.
The budget also sets aside $2.5 million for administration; $275.5 million for operations and maintenance; $306.8 million for environmental and planning studies, project development, construction engineering and management, among other things.
In addition, there is $119.3 million for the State Infrastructure Bank, maintaining the state's mobile equipment and the operation of the warehouse and supply system.
The improvement program sets priorities on transportation projects for federal, state and local funding and plays a role in putting projects into action.
