Comments
I believe the bridge was constructed by the United Railways, not the Oregon Electric. Later on, a line connecting the UR line at Bowers Jct. (just west of the Holcomb Creek Trestle) with an Oregon Electric branchline in Hillsboro was constructed. At the time, the OE's mainline ran from Portland to Eugene, but Portland wanted the railroad off of its streets. The connector allowed the OE to abandon it's direct line into Portland (now occupied by I-5) and instead routed its trains on a more round-about route through Hillsboro, Bower's Jct., this trestle, and Cornelius Pass to come in to Portland from the northwest. Both United Railways and the Oregon Electric were subsidiaries of the Spokane Portland & Seattle Ry., so this arrangement kept all the traffic in the family.
The OE's branch line is now used by MAX light rail, and the Hillsboro-Bowers Jct. connector was severed something like a decade ago. Portland & Western gained control of the former OE and UR lines as well as many Southern Pacific branch lines. Trains arriving in Tigard from the Willamette Valley and points south still travel over this trestle, but they use the former SP line to go through Hillsboro to Banks, where a connection to the former United Railways line is made. The railroad sends one train (once in each direction) over the trestle 5 days per week, Tuesday-Saturday, but unfortunately, the train operates late at night.
The current connection in Banks between the UR and SP lines is a little cumbersome, and the P&W has won a ConnectOregon II grant to build a better connection just east of that town. Once construction is complete, the railroad may begin sending a second train per day over the route.
Who keeps editing this page by adding the railroad initials? I would like it to stop, please.
They use it Daily still
I believe the trestle is no longer open to traffic

Does anyone have any updated information on how frequently the P&W runs trains over the Holcomb Creek Trestle now that the shortcut has been built in Wilksboro (just east of Banks)? I have only been able to get out there on Friday nights to see the train crossing the trestle, but if they are running during the day now, that would be great to see.
