The Oregon Department of Transportation has completed a new single lane detour
next to the Coles Bridge on Highway 26, near John Day. Heavy trucks also are
being rerouted on 99W near King City due to cracks on the northbound bridge.
The new detour along Highway 26 eliminates the 113-mile truck detour that
has been in place since last month. It will accommodate loads up to 105,500
pounds as well as annual permit heavy haul and some single trip permit loads.
It should safely accommodate a tractor-trailer up to 65 feet long and up to
12 feet wide.
The detour also has sharp vertical grades of 7 percent into and out of the
detour. Some long loads will be unable to navigate the detour. Loads requiring
a single trip permit will be allowed on a case-by-case basis.
Beginning today (Aug. 27), ODOT will impose weight restrictions on the northbound
Oregon 99W bridge over the Tualatin River near King City. This weight limit
will affect heavy trucks with single axle weights over 20,000 pounds, tandem
axles over 34,000 lbs. and trucks with a total weight in excess of 105,500
Recent inspections have revealed cracks in the horizontal concrete beams
that support the bridge. Repairs are expected to take six months.
Due to the restriction, Oregon 99W north of Sherwood will no longer be the
official detour for trucks avoiding similar weight restrictions on the Willamette
River Bridge on Oregon 219 south of Newberg. All overweight trucks that travel
north on Highway 99W between Sherwood and King City will be required to use
an alternate route. Southbound trucks on Oregon 99W will not be impacted by
the weight restriction.
