Jefferson North Assembly, US assembly plant
Jefferson North Assembly is a large factory in Detroit, Michigan, that mainly produces Jeep Grand Cherokees and Dodge Durangos. The facility spans roughly 3 million square feet (280,000 square meters) and has multiple assembly lines where machines and over 5,000 workers work together to process vehicles from body work through final finishing.
The facility opened in 1991 and replaced an older factory on the same site that dated back to 1907 and closed in 1990. Since opening, the plant has expanded and modernized through major investments in 1999, 2008, 2019, and 2025 to build new models and increase production capacity.
The name refers to the streets Conner and Jefferson where the facility sits. Inside, workers follow a steady rhythm of assembly, with each person focusing on specific tasks that build vehicles piece by piece.
The location is at the intersection of Conner and Jefferson streets and is easy to reach, but it is primarily a working factory. Visits are possible through organized tours, but the plant is not open for casual visitors, so it is wise to arrange access beforehand.
In 2013, the five millionth vehicle, a silver Jeep Grand Cherokee, was donated to the USO, a charity supporting military personnel. Later, in 2016, the six millionth vehicle was built as a special edition marking Jeep's 75th anniversary and painted in a rare granite crystal color.
