(AP) — Business leaders in Iowa and Nebraska are joining forces to promote economic development in the Omaha-Council Bluffs area.

Govs. Terry Branstad and Dave Heineman signed an agreement Friday to add Advance Southwest Iowa Corp., a new public-private partnership, to the Greater Omaha Economic Development Partnership. The group includes business leaders from Douglas, Cass, Washington, Dodge and Sarpy counties in Nebraska.

David Brown, president of the Great Omaha Chamber of Commerce, says the partnership will work to market the area for new business investment and expansion.

Pete Tulipana, president and CEO of the Iowa West Foundation, says about 18,000 Council Bluffs residents cross the Missouri River each day to work in Omaha, and roughly 6,000 employees travel from Omaha to work in Council Bluffs.
