The Tacoma Eastern railroad was the original railroad operating in the timber lands near Mount Ranier. Until December 31st, 1915, the Tacoma Eastern Railroad was operated as a separate organization with the Chicago, Milwaukee & St. Paul Company owning all of the outstanding stock. On that date the railway, property and franchises of the Tacoma Eastern Railroad Company were conveyed to the Milwaukee Road and operated as part of the Coast Division.
Significant upgrading of the Tacoma Easter Railroad's right of way was deamed necessary. At Mile 51 a crossing of the Nisqually River required a 120 foot Through Timber Howe Truss with a long pile trestle approach. This Through Timber Howe Truss bridge was later upgraded to a 4 span Deck Plate Girder bridge with a shorter Timber Pile Trestle approach.
The WWSL
In the WWSL history, this bridge complex is the third at this location.
The first bridge (built by the OPLC), was a temporary construction (lasting 10 years) consisting of tree trunks as stringers over timber piers. This bridge was replaced after it was seriously damaged by fire.The picture below shows a similar bridge built by the Sound Timber Company. ( D.Kinsey courtesy of Whatcom Museum of History and Art). Someday I'm going to build this bridge as a AP project. See Satsop River Bridge N5c for construction details.
First Bridge (temporary construction)
The second bridge (also built by the OPLC), was a series of Through Timber Howe Trusses. The picture below shows a similar bridge built by the Bloedel-Donovan company (Ed Marlow). These bridges were replaced when the coal and stone loads generated by the O. K. Coal Company and Basalt Sand and Gravel located north of this location exceeded engineering specifications. Someday I'm going to build this bridge as a AP project. See Satsop River Bridge N5d for construction details.
Second Bridge - Through Timber Howe Hruss
Modeling Information
There are 5 bridge elements to be constructed in the Satsop River Bridge section:
- A 5 bent Timber Pile Trestle with a wood abutment. See Satsop River Bridge N5a for construction details.
- Two 14 panel Deck Plate Girder bridges and two 10 panel Deck Plate Girder bridges. See See Satsop River Bridge N5b for construction details.
- 4 unique piers. See Satsop River Bridge NP5 for construction details.
- A concrete abutment for one of the 14 panel bridges. See Satsop River Bridge NA5 for construction details.
