I am not entirely sure that this is an old CRH bridge, but it sure does seem to match the descriptions of the original Honeyman Creek Bridge.

If it is, was it moved, or are all traces of the original CRH alignment in the area plowed under the fields? I wouldn't be surprised by either at this point.

Also there have been some recent wetland restoration nearby involving the construction of new bridges along the creek (see links below). This is older though, turning up on the aerial photos for many years now, and that work was being done on the east side of U.S. 30.

The 4th Biennial Report of the OHC in 1919 describes the construction of an "18' reinforced concrete span over Honeyman Creek on the Scappoose-Deer Island Section, Columbia River Highway, near Honeyman Station." that was completed by November 30, 1920, the final date of the report. (Booth, et al, 4th Bienneium Report 111.)

According to Taylor, "The original bridge was destroyed when the road was widened." This, to me, does not rule out that it could have been moved and re-purposed as a local farm bridge, or bypassed be a minor route re-alignment.

Really, someone needs to go check out this mystery bridge on the ground!

ODOT's study of historic bridges in the early 1980s lists a Honeyman Creek bridge in Columbia County... "Honeyman Creek, #2667, BG [ Slab, Beam and Girder], Ca. 1920, p [Plans Inventory Only]" (Smith et al 302)

According to the data below, the US 30 bridge was reconstructed in 1978 and that span is 27.9 feet... However, that new bridge is also 80 feet wide, which is clearly not the original CRH bridge, nor the one parked in the field. Modern U. S. 30 through here is almost exactly 80 feet wide.

The 1990 image below contains no visible bridge, but it barely shows any sort of creek in the area, either. Slowly over the years, the path of the creek becomes more clear in the aerial photos, and the bridge seems to emerge... Buried? That would be cool, but it seems unlikely.

One final note, the map on the UglyBridges.com shows the Jackson Creek Bridge, south of Scappoose, as Honeyman, which is two miles to the north...

Freeing Honeyman Creek:

"As bewildered cows in a nearby pasture watched their every move, two backhoes piled rocks on either side of Honeyman Creek in Scappoose where a failed culvert had been removed to make way for a new bridge."
