Fremont is quite flat, lying in the river plain between the Platte and Elkhorn rivers, at an elevation of approximately 366 meters (1,203 ft) above sea level. Fremont is the county seat of Dodge County, Nebraska, and is likewise the financial and social center of the area. Facilitated by the completion of the US Highway 275 and Highway 30 bypass around Fremont, from Omaha, eastern Fremont is growing rapidly as a bedroom community for Omaha (see links to air photos below).
