On entering Maine at Kittery in the south, continue northward on Interstate 95 (same as the Maine Turnpike in southern Maine) for about 50 miles to the Portland area.

At Portland, take the Interstate 495 (formerly I-295) loop through the city, rejoining I-295 (formerly I-95) near Falmouth at exit 11 (formerly exit 15). Continue north on I-295. Do NOT take the Maine Turnpike (I-95) to Augusta. Take I-295 towards Falmouth, Yarmouth, Brunswick, and Augusta. Stay on I-295 North; do NOT take scenic US Route 1 towards Bath (unless you want to).

Driving to Union from the Portland Airport, you would miss the shortcut I-495 loop, getting onto I-95/Maine Turnpike northbound at exit 45 or 48 (formerly exit 7 or 8). Get off the Turnpike (which becomes I-95) at exit 52 (formerly exit 9) and get onto I-295 towards Brunswick and Augusta.

On I-295, about 50 miles from Portland and before Augusta, take exit 51 (formerly exit 28) and go east on US Route 9 to the business district of Gardiner.

As you enter the city of Gardiner on Route 9, you will turn left over the Cobbosseecontee Stream at the traffic lights across from the Post Office (there is a cute old-fashioned "A-1 Diner" built right on the bridge). In a few more blocks you will be at the Kennebec River. Leave Route 201 and go straight over this large bridge (over the Kennebec River, now on Routes 27 South and 126 East). While on the bridge, get into the right lane and turn right after crossing the bridge (so you are on the east side of the Kennebec River, heading south). Go about a quarter mile and turn left onto State Route 226 North (at the auto body shop on left side). This is poorly marked: if you get to Pittston, you missed the turn! Drive north on Route 226 until it T's into Route 17 at Abbot's Market & Deli (you must turn right or left). Turn right onto Route 17 and go eastward towards Rockland for about 30 miles, through Cooper's Mills, Windsor, Washington and then to Union.

As you come into Union from the west (you will not see the town itself because Route 17 bypasses to the north of the town common) you will see Union Farm Equipment at the junction of Route 17 and Route 131 North. You can't miss the New Holland sign and the many pieces of equipment visible from the road.

From Camden/Rockport/Rockland:

If you are starting in Camden, take Route 90 through Rockport and turn eastward on Route 17. From Rockland, take Route 17 all the way. Proceed through Hope, past the junction of Routes 17 and 131 South. Union Farm Equipment is located on the northeast corner of the intersection of Route 17 and Route 131 North.
