Interstate 84 Oregon - Highway Guide

Interstate 84 - Oregon

Routing

Interstate 84, which was designated as Interstate 80N until 1980, joins Portland and the Interstate 5 corridor with interior Oregon and Boise, Idaho. Much of the route is cosigned with U.S. 30 in the state, as the freeway replaced the original Columbia River Highway. The drive through Columbia River Gorge is arguably one of the most beautiful stretches of the Interstate highway network within the entire country.

Much of Interstate 84 is also signed as U.S. 30 along the Columbia River. The two routes continue eastward from the Umatilla Indian Reservation and climb into the Blue Mountains east of Pendleton. The freeway curves southeastward from Emigrant Hill through Deadman Pass and southward to a summit of 4,193 feet above sea level near Meacham. Along the eastward drive from Exit 216 to 224, vista points allow motorists a chance to take in the expansive nature of the western desert like horizon before the freeway leaves for La Grande. The two carriageways of the freeway separate by quite a distance to make their respective journeys.

Highway Guides

Scenes Pertaining to Interstate 84: Emigrant Hill
Looking north at Interstate 84 & U.S. 30. The view point lies five miles east of Exit 216. Photos taken 08/31/06.
Northwesterly view of Interstate 84 & U.S. 30 from Umatila Indian Reservation (Exit 216) east. The scenic pull off doubles as a chain up area for wintry weather in the forthcoming Blue Mountains. Photo taken 08/31/06.
Vast ranch lands spread out over the basin west of the Blue Mountains. Much of the land is arid due to the rain shadow effect of the Cascade Mountains. Photo taken 08/31/06.

Interstate 84 & U.S. 30 east continue their eastward rise toward Red Hawk Gulch independent of the westbound carriageway. The Interstate 84 & U.S. 30 vista point was reserved as part of the 1961 Oregon Scenic Areas Act, which designated 3,585 miles of highways as scenic routes in Oregon. Photo taken 08/31/06.
Storie Lane follows Patawa Creek southeast to a small settlement west of the Interstate 84 & U.S. 30 climb. Photo taken 08/31/06.

Bonneville and Bonneville Dam
Tanner Creek Road joins Interstate 84 & U.S. 30 (Exit 40) with Bonneville Dam and Dam Road east/Hatchery Road west at Bonneville. Pictured here is the guide sign on the road northbound at the Exit 40 diamond interchange. Photo taken 08/28/06.
Dam Road north stems northeast from Tanner Creek Road and Hatchery Roads to Bonneville Dam. A swing bridge spans the navigational canal onto Robins Island. Photo taken 08/28/06.
Bonneville Dam generates hydroelectric power and includes fish ladders used by salmon and steelhead swimming upstream during their mating season. The dam is open to visitors on a daily basis. Photo taken 08/28/06.
Bonneville Reservoir is formed by the Bonneville Dam to the east. The Dam was named after Army Captain Benjamin Bonneville, an early explorer associated with the Oregon Trail.1 Photo taken 08/28/06.
Due to the narrow nature of flat land between the Columbia River and the edge of Mt. Hood, Interstate 84 splits between a westbound viaduct and eastbound tunnel at Bonneville. In view here is the elevated roadway for eastbound and the adjacent Union Pacific Railroad line below. Photo taken 08/28/06.
One of the fish ladders (Bradford Island Fishway) that allow the passage of sturgeon and steelhead beyond Bonneville Dam. A viewing room allows visitors an underwater look at the current fish must overcome to make the trek east. Table Mountain in Washington rises along the horizon. Photo taken 08/28/06.
A navigation canal and locking system lies between Robins Island and the south banks of the Columbia River. Photo taken 08/28/06.
A closer look at Bonneville Dam and associated spray. Photo taken 08/28/06.
Massive power lines carry electricity generated from the powerhouse northward into Washington state. The dam has supplied power to the region since 1938. Photo taken 08/28/06.
Robins Island lies midway between the Columbia River north banks and Bradford Island. The island includes a Recreational Area and is joined to Bonneville by a narrow swing bridge. Photo taken 08/28/06.
Crossing Dam Road south over the navigational canal at Bonneville Dam. Photo taken 08/28/06.
A fish hatchery lies west of the intersection of Dam and Tanner Creek Roads adjacent to the south banks. Visitors are provided with access to a large tank to view some of the larger resident steelhead, sturgeon and salmon. Photos taken 08/28/06.
Leaving Bonneville on Tanner Creek Road north; a diamond interchange provides return access to Portland via Interstate 84 & U.S. 30 west and Hood River via east. A Union Pacific Railroad line (pictured in the foreground) parallels Interstate 84 through much of the Columbia River valley. Photo taken 08/28/06.
Vista House
Magnificent views are afforded to visitors of the Vista House high above Interstate 84 & U.S. 30 and the Columbia River. Photo taken 08/27/06.
Crown Point and Rooster Rock State Parks surround the Vista House and Interstate 84 & U.S. 30's path through this stretch of the Columbia River Gorge. Photos taken 08/27/06.
A traffic accident blocked the eastbound lanes of Interstate 84 & U.S. 30 at Exit 22 (Corbett Station), resulting in extremely long back-ups in both directions. Note that several sections of Interstate 84 travel along causeways between the river and wetlands associated with Young Creek and Mirror Lake. Photos taken 08/27/06.
Interstate 84 & U.S. 30 at Rooster Rock, far below the Vista House and Historic Columbia River Highway (old U.S. 30). A trumpet interchange (Exit 25) joins the freeway with the Park's main access point and parking area. Photos taken 08/27/06.
Rooster Rock State Park
Eastward view from Rooster Rock State Park near Interstate 84 & U.S. 30. The park includes three miles of beaches, a boat ramp, the two-mile Volkswalk trail and even a nude beach. Photo taken 08/27/06.
Nearing sunset at Rooster Rock State Park. Winds through the Columbia River Gorge during the winter have topped at 110 mph. On this day, there was hardly any wind and temperatures instead soared to the mid to upper 90s. Photo taken 08/27/06.
Washington state rises along the north banks of the Columbia River, opposite Rooster Rock State Park. Photo taken 08/27/06.
Exit 25 consists of a trumpet interchange sandwiched between wetlands south of Interstate 84 and Rooster Rock State Park. There is no access to the Historic Columbia River Highway (old U.S. 30) from here. Photo taken 08/27/06.
Rooster Rock State Park lies along the south banks of the Columbia River at Interstate 84 & U.S. 30 Exit 25. The park is only accessible by the freeway. Photo taken 08/27/06.
Scenes Pertaining to Interstate 84
Corbett Hill Road meanders upwards from Interstate 84 & U.S. 30 (Exit 22) at Corbett Station to Historic Columbia River Highway (old U.S. 30) at Corbett itself. This view looks at the eastbound on-ramp signage for Hood River. The missing trailblazer directed motorists to the Vista House. Photo taken 08/27/06.
Peering westward from the Corbett Hill Road diamond interchange (Exit 22) at Corbett Station. Photo taken 08/27/06.
Chenoweth Road westbound at the Interstate 84 & U.S. 30 eastbound on-ramp at Exit 82. Historic Columbia River Highway (old U.S. 30) enters from a parallel alignment to become West 6th Street in the Dalles. Photo taken 08/28/06.
Looking north from the Columbia Gorge Discovery Center area west of the Dalles, adjacent to Interstate 84 & U.S. 30. Hugging the north banks of the river is a BNSF Railroad line. Washington 14 (former U.S. 830), leaves the river area for higher elevations just west of this scene. Photos taken 08/28/06.
