Interstate 280

Interstate 280 may refer to:

Interstate 680 (Iowa–Nebraska)

Interstate 680 (abbreviated I-680) in Nebraska and Iowa is the northern bypass of the Omaha – Council Bluffs metropolitan area. I-680 spans 42.86 miles (68.98 km) from its southern (counterclockwise) end in western Omaha to its eastern (clockwise) end near Neola, Iowa. For a 10-mile (16 km) stretch, I-680 is co-signed with I-29. The freeway passes through a diverse range of scenes and terrains – the urban setting of Omaha, the Missouri River and its valley, the rugged Loess Hills, and the farmland of Pottawattamie County, Iowa.

Until 1973, the section in Iowa between the current eastern end and I-29 was designated as Interstate 80N. I-680 in Omaha was originally designated Interstate 280. Maps from the early and mid-1960s showed I-280 in Omaha. Since this highway would extend into Iowa, and I-280 was already planned for the Quad Cities area, this route was redesignated I-680.

Route description

Interstate 680 begins at a complex interchange with I-80 in Omaha. Due to the proximity of the West Center Road interchange on I-680 and the I, L and Q Street interchanges on I-80, all of the exit and entrance ramps which connect I-80 to I-680 also connect to West Center Road and I, L and Q Streets. The freeway heads north through the heart of West Omaha; it serves as a dividing line of several residential neighborhoods.Two miles (3.2 km) north of West Center Road, which prior to 2003 was N-38, is a new interchange with U.S. Route 6 (US 6), known as Dodge Street in Omaha. Another mile north of Dodge Street is N-64, known as Maple Street.

Interstate 280 (California)

Interstate 280 (I-280) is a 57-mile (92-km) long north–south Interstate Highway in the San Francisco Bay Area of Northern California. It connects San Jose and San Francisco, running along just to the west of the larger cities of San Francisco Peninsula for most of its route.

I-280 from its southern terminus at U.S. 101 and Interstate 680 north to Interstate 880 in San Jose is part of the Sinclair Freeway. From I-880 to State Route 1 in Daly City, I-280 was built and dedicated as the Junipero Serra Freeway, after the Spanish Franciscan friar who founded the first nine of 21 Spanish missions in California from San Diego to San Francisco. One of the dedication signs (in Daly City) still indicates that the Junipero Serra Freeway is known as the World's Most Beautiful Freeway due to its scenic route through the San Francisco Peninsula. From State Route 1 to the James Lick Freeway U.S. 101 in San Francisco is officially called the John F Foran Freeway (after a former member of the California State Legislature), but is more commonly referred to by its original name, the Southern Freeway. And from the James Lick Freeway to its northern end at King Street and Fifth Street, I-280 is called the Southern-Embarcadero Freeway.
