Oregon bridge detour, restrictions

| 8/27/2001

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 lbs.

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.
