Detailed Information About Demolition and Replacement Project 

Excerpts Taken From WSDOT Biological Assessment Document

The Manette Bridge was identified as both structurally deficient and functionally obsolete. As a result of this assessment, the bridge was added to the WSDOT Bridge Replacement Priority Array List in December of 1993.

The Manette Bridge was originally built in 1930. The bridge was constructed with five steel truss main spans on six concrete piers. A 1949 contract replaced the original wooden deck and timber trusses in the outer spans with concrete and steel. The primary areas of structural deficiencies are in the concrete piers and the structural steel trusses, which are nearing 80 years old. The concrete in the foundations is in varying states of deterioration.

Overall, the substructure components are in poor condition at the main piers (built in 1930) and in satisfactory condition at the approach piers (built in 1949). Columns and pier walls at the main spans exhibit leaching cracks, rust stains, delaminations, soft concrete, and formwork holes.

The foundation is exposed at all piers in varying degrees. Repairs to the main concrete piers were completed in 1949 (Piers 4 and 6) and 1991 (Pier 5) and 1996 (Piers 4 and 6). These repairs attempted to encase the deteriorating concrete in the concrete foundations but were not effective.

Based on these deficiencies as well as other considerations, it was determined that replacement of the bridge is warranted and necessary. The Legislature and the Governor have provided approximately $65 million for the replacement of the Manette Bridge over the next 8 years with construction of the new bridge scheduled to begin in 2010 although construction my be accelerated and begin in 2009.

The Manette Bridge is located in Bremerton, Kitsap County, Washington. The bridge spans the Port Washington Narrows, a 3.5 mile long and 0.25 mile wide fjord which connects Dyes Inlet with Sinclair Inlet. The bridge is critical to the Bremerton community, providing a link between the eastern and western portions of the city. The proposed project will replace the existing bridge with a new concrete bridge. The new Manette Bridge will be built parallel to and immediately south of the existing bridge. The project will take three years to complete.

The proposed project will replace the structurally deficient and functionally obsolete Manette Bridge with a new concrete bridge. The new Manette Bridge will be built parallel to and immediately south of the existing bridge, with roadway connections to existing city street intersections on each end of the bridge. Construction of the project is proposed to begin in 2010 and continue for approximately 3 years.

First, the new bridge piers and central portion of the new bridge will be constructed. Second, the outermost spans of the existing bridge will be removed and the new bridge’s outermost spans and abutments will be built. This work includes the completion of stormwater facilities for the new bridge. Finally, the remaining portions of the existing bridge will be demolished and removed. The construction elements associated with these phases are summarized below and detailed in the following section Construction Sequencing and Project Elements.

The demolition of the existing bridge will occur in phases over a period of 18 months. After the central portion of the new bridge is constructed, the outermost spans and abutments of the existing bridge will be demolished and removed. Once the new abutments and outer spans are constructed, the demolition of the remainder of the existing bridge will proceed.

The bridge structure above the water line will be cut into manageable sections, using conventional concrete and metal cutting tools, or a wire saw, and placed on barges for transport to approved waste or recycling sites. Pavement will be removed using a hoe ram. The portions of the piers below the water line will be cut into pieces using a wire saw. All slurry from wire cutting operations above the water line will be contained and removed; below the water line it will be dispersed by the current. The piers will be cut off at the ground level. Pier armoring will also be removed, although the exact amount is unknown. Based on the known quantities of rip rap placed around the piers and inspection reports, WSDOT estimates that approximately 12,000 cubic yards of riprap is currently in place around existing bridge footings, all of which will be removed. Because the new bridge will not have footings, riprap will not need to be replaced.

You assume that WSDOT even cares to any extent about the loss of history and can be persuaded to spare at least some of the remaining trusses for study or recreational purposes. Their historian Craig Holstine finally got around to determining that this bridge was eligible for the NRHP as demolition began.

This is how WSDOT treats our nation's transportation heritage. This is one of a bunch of photos they took, so I guess they are proud of this senseless destruction.

If you are looking for a reason to never visit Bremerton, I think this is a pretty good one:

There was a hoopla this past weekend as the replacement opened for public use. The railings on the new are still being fastened on but they certainly are not wasting time tearing down the old one.

The Kitsap Historical Society had a "Bridges of Kitsap County" exhibit earlier in the year as their way of saying "Goodbye". Some of the items documented and images found were made into a scrapbook offered for sale.

The Union Bridge Company built Manette Bridge at a cost of $525,000. Work done in 1949 replaced the timber portions of the bridge which were mainly the approaches on either end.

Helen Adele Joldersma inaugurated the bridge and other dignitaries included a 100 + year old Native woman, a relative of Chief Sealth.

Tolls were collected at various times during it's life span but not since the early 1970s.

The lost twin of the Sauvie Island is a good analogy.

Here pretty soon, both twins will be lost to the ages.

I have been taking the Warren Avenue Bridge, one reason, Ugly New Bridge is Ugly. Manette does not look good either, the DOT has stopped taking care of it. My January 2010 images are better than my cell phone pictures in August when the pile-driver barge was offshore for new bridge and a half dozen DOT workers observed from the Manette leaning on the rail. The dedication plaque has disappeared. I received odd looks when I pressed the workers about it, you know the type where there is a unicorn horn coming out of your forehead odd. I'll post the cell phone images if there is interest and can stop by again tomorrow on my way to Bainbridge Island. Iffy weather predicted though. We'll see. I might have a postcard image to upload ... I have to look around.

I've always thought of the Manette as a lost twin to the Sauvie Island Bridge.

This bridge is to be demolished in November 2011. I am hoping one of the state's frequent contributors might go and take a bunch of photos of this bridge before it is demolished, since there currently are no photos for the bridge. Sadly, this bridge is a little outside of my own feasible coverage region.

I am beginning to think that WSDOT has been watching Pennsylvania's PennDOT and has got it in their head that there must be some sort of reward for being the first DOT to destroy every historic bridge in the state.

As for the replacement bridge? Extreme ugliness. Extreme slab of concrete. See attached.
