Current Oregon trucking load restrictions: Oregon Trucking Online
March 22, 2023
The Harrisburg Bridge over the Willamette River on OR 99E between Albany and Junction City now has a weight limit affecting commercial trucks, but not passenger vehicles.
We have posted limits of 36 tons for seven-axle trucks and 33 tons for three-axle emergency vehicles based on an inspection and load rating in February using updated Federal Highway Administration guidelines. Prior to this month, the bridge had not been load-restricted since we last inspected it in December 2021.
We have established a detour for vehicles that exceed these weights using state and local roads:
- Southbound: Territorial Road and Diamond Hill Road to Interstate 5.
- Northbound: OR 99W to Corvallis, then east on OR 34.
The Harrisburg Bridge is a 2,146-foot structure built in 1925. We added concrete approach spans to the bridge in 1976. The most recent maintenance was in 2021 when we replaced steel bracing and repainted the bridge to extend the life of the structure.
