Customers renting cars at Miami International Airport will now be paying more to offset rising construction costs for a $370 million car-rental facility, Miami Today reports.

Miami-Dade commissioners recently raised the $3.25-per-day customer-facility charge to $4 during the construction period beginning in October and to no more than $4.60 once the facility is operational in 2011. The fee would increase by 25 cents every five years after the facility opens.

The car-rental facility is part of the planned $1.3 billion Miami Intermodal Center next to the airport that is to connect passengers with Tri-Rail, Amtrak, buses, car-rental facilities and a planned extension of the Metrorail system linking the center to Earlington Heights.

Commissioners are responding to higher construction costs to build the facility, which is to be home to 16 car-rental companies. To cover higher-than-expected costs, a federal loan of $164 million will be increased to $270 million.
