Heavy Equipment Repair in Yulee, FLThe fastest growing ground in Nassau County.
Mobile equipment repair in Yulee and Nassau County. Site work on the Wildlight build out, the SR 200 corridor between I-95 and the coast, and the mill and port traffic that has run through here for decades.
Nassau County is building, and the equipment shows it.
Yulee has changed faster than almost anywhere else on our list. Wildlight, the master planned community Rayonier started here, covers around four thousand seven hundred acres with roughly four thousand one hundred homes planned, and Rayonier moved its headquarters into it. Wildlight Commerce Park is building toward twelve buildings and one point six million square feet.
That is a lot of site work in one place, and it sits on top of an area that already ran heavy. I-95 exit 373 at SR 200 is the gateway to Amelia Island and the road to the Port of Fernandina, and the SR 200 corridor is a four lane arterial expanding to six. The forest products mills at Fernandina Beach employ well over a thousand people between them.
The result is a mix of new construction equipment and long established industrial iron working the same roads. Excavators and dozers on residential pads, timber and freight moving on the corridor, port equipment at the end of it, and First Coast Railroad interchanging with CSX right here in Yulee.
Exit 373 is the landmark. Almost everything here is described relative to the I-95 and SR 200 interchange. Tell us which side of it you are on and how far along, and we will find you.

01
I-95 exit 373 at SR 200
The interchange everything runs through, and the way in from our side. Exit 380 at US 17 covers the north end of the county.
02
The SR 200 and A1A corridor
A four lane arterial expanding to six, running from the interstate east toward Fernandina Beach and the port. Most of the commercial ground is on it.
03
Wildlight
Four thousand seven hundred acres under development with a commerce park building out alongside it. Site work, utilities and vertical construction all at once.
04
Wildlight Commerce Park
Two buildings up already at one hundred and forty nine thousand and sixty eight thousand square feet, with a much larger build out planned.
05
The rail interchange
First Coast Railroad interchanges with CSX at Yulee. Rail served industrial ground and the equipment that works it.
06
The Fernandina mill corridor
Smurfit Westrock, Rayonier Advanced Materials and LignoTech operate at Fernandina Beach, about fifteen minutes east, and the traffic runs back through Yulee.

Questions we get
Yulee equipment repair questions.
How long does it take you to reach Yulee?
About an hour on a normal run, up I-295 and across. Time of day matters more here than distance does, because it means crossing Jacksonville.
Which exit do you use for Yulee?
I-95 exit 373 at SR 200 and A1A is the main one. Exit 380 at US 17 covers the northern end of the county. Tell us which is closer to your site.
Do you work on the Wildlight development?
Yes. It is the largest concentration of site work in Nassau County and the machines on it run hard. Access changes as they build, so let us know how a service truck gets in.
Do you repair logging and timber equipment?
Yes. Skidders, loaders, log trucks and landing equipment. Lumber and wood products are far and away the biggest freight movement out of Nassau County.
Can you get to the port or the mills at Fernandina Beach?
Yes, they are just east of Yulee down the SR 200 corridor. Site access rules at the port and the mills vary, so mention what is required when you call.
Is SR 200 construction going to slow you down?
The corridor is being widened from four lanes to six, so conditions along it change. It affects timing rather than access, and we will factor it into the window we give you.
Do you service equipment in the commerce park?
Yes. Yard equipment, material handlers and the construction fleets working the buildings that are still going up.
Do you cover Fernandina Beach and Amelia Island?
We take calls from that side of the county. Tell us where the machine is and we will be straight with you about whether we can get there in time to help.
Tell us the machine, the symptom and where it sits. If we can help, you will know on the first call. If we cannot get to you in time to do any good, we will say that too.
