Bridge. The toll bridge crosses the Columbia River and connects Hood River to White Salmon, Washington and has a regular toll of $2 per vehicle. The freeway continues southeast along the Bingen Gap and enters Wasco County near Kobert Beach. Upon reaching Mosier, US 30 splits from I-84 and travels inland along the Historic Columbia River Highway while I-84 remains near the riverbank, passing through Memaloose State Park. The two highways run parallel to each other and the Union Pacific Railroad through Rowena and turn south while approaching The Dalles. The highways pass the Columbia Gorge Discovery Center & Museum and through the suburban areas of the city, separated from the river by an industrial park that includes a major data center for Google. The freeway returns to the river near downtown The Dalles, crossing southeast over US 30 twice as it remains on city streets. US 30 returns to I-84 east of The Dalles at an intersection with US 197, which travels south towards Bend and north across The Dalles Bridge to WA 14 near Dallesport, Washington. The freeway passes The Dalles Dam and continues northeast around the foot of Signal Hill and Kaser Ridge to Celilo Village, where it intersects OR 206. OR 206 continues along the south side of the freeway as both roads cross the Deschutes River into Sherman County and travels southeasterly towards Condon. The Deschutes River marks the eastern end of the Columbia Gorge National Scenic Area, though the gorge itself continues further northeast through the shrublands of the Columbia Plateau. I-84 and US 30 travel northeast to Biggs Junction, where it intersects US 97 at the south end of the Sam Hill Memorial Bridge, which continues across the river to Maryhill State Park in Maryhill—an early planned community by businessman Sam Hill that features a Stonehenge replica and had the first paved roads in the Northwest. US 97 also continues south from Biggs Junction to Bend and north to Goldendale and Yakima. The freeway continues northeast through Rufus and past the John Day Dam to the John Day River, where it crosses into Gilliam County. Eastern Oregon I-84 and US 30 continue east along the river, now the expanded Lake Umatilla, and reaches Arlington at the foot of Alkali Canyon. There, it intersects OR 19 in an interchange that is split into two halves by Earl Snell Memorial Park. OR 19 travels south
