The portion from Sandy to Barlow Pass on the south flank of Mount Hood is aligned to the land portion of the historic Oregon Trail. It was developed in the 1840s as the Barlow Road.

After crossing the Willamette River on the Ross Island Bridge, the Highway is locally known as Powell Boulevard through Portland and Gresham. State maintenance ends at the Portland/Gresham border, beginning again where the Highway turns southeast at Burnside Street east of downtown Gresham. Soon after that turn, Highway 26 uses the completed part of the Mount Hood Freeway (built only to surface expressway standards) to Sandy, where it runs through downtown on a one-way couplet.
The section of Powell Boulevard from Interstate 205 east into downtown Gresham carries only two lanes. When I-205 was built, the ramps at Powell Boulevard were configured to only allow traffic towards the west, with US 26 east pointed along the four-lane Division Street, about 1⁄2 mile (0.80 km) to the north. (Right turns were even banned to and from the I-205 north ramps at first.) Division Street runs east into Gresham, where it meets Burnside Road, at which a right turn to the southeast leads into the Mount Hood Highway and US 26. Despite this signage pointing US 26 east on Division Street, traffic already on US 26 is pointed straight along Powell Boulevard (the Mount Hood Highway), in agreement with ODOT's route description.[1][2]
East of Sandy, the highway is a (mostly) four-lane undivided highway approaching the slopes of Mount Hood; as the highway climbs up towards Government Camp it reduces to two and three lanes. It is four lanes again through Government Camp. East of Government Camp is an interchange with Oregon Route 35, where US 26 heads southeast on the Warm Springs Highway towards Madras and the Mount Hood Highway heads north with Route 35.
Route 35 winds over Bennett Pass and around the eastern side of Mount Hood, and descends into the Hood River Valley. The Mount Hood Highway designation ends at the intersection with the Historic Columbia River Highway, which carries U.S. Route 30 to the west. To the north, the road continues as a spur of the Columbia River Highway No. 2 (Interstate 84), bringing US 30 back onto that freeway. Officially Route 35 heads west from there on US 30 through Hood River to end at I-84 west of that town, but all signage ends at the end of the Mount Hood Highway.
The general public uses the name Mount Hood Highway to refer to much the same route, excluding the portions inside Portland and western Gresham (which are referred to by the street name of Powell Boulevard).
Between 1955 and 1978, the 15-mile (24 km) segment of the route through southeast Portland was proposed to be moved from Powell Boulevard to a new similar alignment known as the Mount Hood Freeway. Due to intense local opposition, this proposed freeway was cancelled.
Scenic Byway
From Troutdale, the Mount Hood Scenic Byway starts at the end of the Historic Columbia River Highway where the Troutdale Bridge crosses the Sandy River. For the first twenty miles (32 km) of the route, it follows a southwestern path along city streets: west on Glenn Otto Park Road into downtown Troutdale, connecting with Halsey Street, south along 238th Street (which veers to become 242nd Street), Burnside Street, Orient Drive, Dodge Park Boulevard, Lusted Road, and Ten Eyck Road.

The Byway continues into Sandy on US 26, heads west briefly on a spur to Jonsrud Viewpoint on Bluff Road, then backtracks to US 26.
It continues along U.S. Route 26 for about thirty miles, then leaves the highway proper in favor of the business loop through Government Camp. The Byway follows a spur just east of Government Camp to Timberline Lodge. After returning to US 26, it continues to the junction with Oregon Route 35 where it exits US 26 and goes north on OR 35 for about 40 miles (64 km). At the eastern outskirts of Hood River, OR 35 intersects with U.S. Route 30 and the Historic Columbia River Highway.
