The New United Motor Manufacturing Inc. plant (or NUMMI) - a joint venture plant between Toyota and GM - will cease production by March 2010.
The plant currently produces the Toyota Corolla and Tacoma utility (pictured above).
Corolla production will shift to Toyota’s Cambridge, Ontario, Canada plant, but it remains unclear where Tacoma production will be moved.
The NUMMI plant, which currently employees 4700 workers, opened in 1984 as a 50:50 joint venture between Toyota and General Motors.
The plant's future had been unclear since GM announced it was closing its Pontiac division, the Pontiac Vibe was produced at NUMMI, and was withdrawing from the venture.
Today's announcement will mark Toyota's first US plant closure with at least one UK plant expected to halt production and one Japanese plant to suspend production next year also as Toyota manages it first loss and declining demand.
