HARRISBURG – We updated weight restriction signs today for the Harrisburg Bridge over the Willamette River on OR 99E between Albany and Junction City to clarify how new weight limits apply to some commercial vehicles. The limits do not affect passenger vehicles.
The bridge is open for most commercial vehicles under legal weight limits, but after a new load rating, these limits apply as of March 15:
- Seven-axle vehicles, under the SU7 category for commercial vehicles, are limited to 36 tons.
- Three-axle emergency vehicles, under the EV3 category for commercial vehicles, are limited to 33 tons.
- No heavy-haul trip permits will be issued for the Harrisburg Bridge.
For SU7 and EV3 trucks that exceed the limits we have detours available:
- Southbound: Territorial Road and Diamond Hill Road to Interstate 5
- Northbound: OR 99W to Corvallis, then east on OR 34.
Loads that need an over-weight permit will need a route assigned by the Over Dimension Operations section of ODOT. Extended-weight permits (up to 105,500 pounds gross weight) can cross if they have a permit and they have legal axle and group axle weights. Heavy-haul permits (moving a single, non-divisible item with heavy haul weights) cannot cross it.
We posted the new limits this month based on an updated inspection and load rating in February. Prior to this month, the bridge had not been load-restricted since we last inspected it in December 2021.
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.
