JACKSONVILLE, Fla.- Site preparation work for a 5,500-seat amphitheater next to EverBank Field could begin as early as April, a Jacksonville Jaguars spokesperson confirmed to First Coast News.

The "Request for Proposal" deadline for the amphitheater and adjacent indoor "Flex Field" project is the end of March with a decision on which firm to oversee the project expected in early April. The Jaguars will use the flex field as an indoor practice facility.

Both facilities are part of a $90 million deal the team reached with the city of Jacksonville. The city is paying $45 million of the cost of the two facilities and the team will pay for the rest.

The projects will be built between the south side of the stadium and Gator Bowl Boulevard/Bay Street.

Early work on the project will be mostly laying of utilities and site preparation, the spokesperson tells First Coast News. The final design of the project has not yet been approved. No timeline for completion of the Ampthitear or flex field has been set yet.

The team also began a major overhaul of the club areas of Everbank Field in January. That project is expected top be complete in time for football season this fall.

Below are photos the Jaguars released in January of both projects.
