HISTORIC COVERED BRIDGE RESTORATION HAS BEGUN

Mobilization by Spectra Contractors of Pomona, California, have begun installing fencing, office trailers and equipment in preparation for a major renovation of the historic covered bridge at South Yuba River State ParkBridgeport in Penn Valley, California.

 

Built in 1862, the bridge has undergone other renovations and repairs with this being a major undertaking. Once the project is completed, expected in the fall of 2020, it will be eighteen inches higher with new shingles, sidings, floor planking, interior trusses and steel tension rods.

Progress photos will develop on a daily basis with eventual aerial drone coverage and You Tube stories at this page(See Restoration Progress - June, 2019).

 

The South parking lot is closed during the project, however the North parking remains available for public use.

 

The Visitor Center, Barn and Gas Station will remain open as well as weekend gold panning and beach access.

For more information, please call 530-432-2546.

The reconstruction project on the Bridgeport Covered Bridge is moving forward. A construction contract was awarded to Spectra Company in the fall of 2018. The total project cost is $6.9 million. Spectra Company will begin mobilizing materials and equipment this spring in preparation of starting construction in late spring or early summer, once water levels are safe. Construction is expected to be completed by the end of 2019.

 

 

A new website has been created by DPR staff for the Project. It is quite extensive and has a lot of the plans, history, drawings and reports related to the Project. It is available for anyone to access.

Bridgeport Covered Bridge Rehabilitation & Restoration

 

RECAP: April 2021
Submitted by John Field
 
Work and progress continued at a very efficient pace in the month of April. Most of the carpenters worked six - ten-hour days per week performing various larger tasks together and in separate groups for smaller tasks simultaneously.
 
Some of the completed highlights consisted of (but not limited to) the completion of the top chords and the drilling for the truss rods; Arch buckets (or thrust pads) for the arch ends at each abutment were installed and secured to the pilaster rebar; The template was created for all the arch segments, and many of the arch segments were milled on site by the carpenters using very large circular power saws and hand planes. All of the truss rods were installed including the re-installation of the eight “chosen” original Wrought Iron rods with “Maker’s Marks.”
 
As a special note, the Chief Carpenter and Bridgewright, Tim Andrews had this to say: “The first round of tightening the truss rods, and tuning (sounding) the main and counter braces is completed. We began the tightening/tuning operation starting from mid-span and progressed towards the abutments, while working in unison from mid-span to abutments, tightening panel points 13 and 15 at the same time, etc. We measured the amount of camber prior to the start of the tightening/tuning operation and after completion of the same. An increase of one inch of camber at midspan was developed and recorded. By definition, we have "trussed" the bridge by tightening the truss rods. The development of additional camber through the tightening/tuning process is proof positive that any "slop" that might have been present during the fit up of the main and counter brace, has been removed. Both the main and counter braces "sing" as they should when struck with a wooden mallet. Moderate pressure was applied using 3-foot-long wrenches to tighten the truss rods.”
 
The second round of truss rod tightening/tuning will be done 14 days from the completion of the first round allowing for settling and relaxation of the trusses and chord components.
 
In addition to the busy April schedule, steel channels and gusset plates were installed on the upper chords which will accommodate the chord bracing of the upper chords together from side to side by means of steel “X-Bracing”. Finally, the concrete forms for the pilasters and the portal approach curbs were built.
 
This recap is a mere abbreviation of the work and complexities involved.
