If you go to Google Earth and look at the Rowena Loops and Mayer State Park area, then turn the clock back to 1996, you'll see where the Rowena Ferry Road used to cross I-84 on a concrete bridge. Then it crossed the Union Pacific railroad tracks on an old wood bridge. Somewhere between 2000 and 2003 a new road on the river side of the railroad tracks was built, then both bridges were removed. The road continued past Bikini Pond to the Columbia River. If you go to Bikini Pond the road will clearly stand out as it is paved on top of a big causeway. Where it dead ends at the Columbia is where the Rowena end of the Rowena-Lyle ferry was. I remember fishing there as a kid and driving over that rickety old wood bridge. I still fish there, and there are few clues a bridge was ever there except for the sloped approaches, which are not really noticeable unless you know where to look (which is at the top of where the present road climbs steeply).
