Aluminum fence cost $20M to build, 10,000-pound aluminum fence costs $20 million

A $20-million, 10-foot-long aluminum fence designed to keep out mosquitoes is expected to be built on the southern Florida coast.

The $20.9-million fence is expected by Florida State University to be ready for the next hurricane season, but the project is not without challenges.

The fence will be used in storm-water control and to monitor water quality for residents along the coast, according to the University of South Florida.

The University of Florida said the fence is being built by a consortium of local, state and federal partners, including the Federal Emergency Management Agency.

The University of Miami said it is building the fence at its Alhambra campus.

The university said the project cost $15 million and was financed by a $6.5 million grant from the Federal Flood Insurance Program.
