Construction Enterprises Inc. is proud to have their 8kip brackets used on the Manette Bridge replacement in Bremerton, Washington.
Contractors are working to replace the 80-year-old Manette Bridge for a wider and safer bridge, which was built in 1930, is structurally deficient and functionally obsolete.
When the new bridge is complete in early 2012, an expanded and reconfigured viewscape will tie in with a new roundabout. Federal dollars comprise 95 percent of the $57.8 million project.
In March 2008 the maximum allowable vehicle weight crossing the bridge was reduced as a result of findings from routine inspection of the bridge. Reducing the stress of heavy vehicles on the bridge extends its useful life and keeps it operational until the new one is constructed.
Construction Phase
The new bridge will be built immediately south of the existing bridge. The existing bridge remains open to traffic for most of the new bridge construction. The bridge will be closed to motor vehicle traffic for up to four months while the outer spans of the new bridge are built. Pedestrians will be able to use the existing bridge during this period.
Additionally, 34 individual 24-hour closures and several morning and evening closures of the existing bridge will occur for the concrete pours, post-tensioning work and other construction activities. Pedestrian access will be maintained during these closures.
The End Result
The new Manette Bridge will be a structure built to current codes and engineering standards and will accommodate motorists, bicyclists and pedestrians. This project will preserve the important connection across the Port Washington Narrows and improve mobility and safety in the Bremerton area.
8 kip Bridge Overhang Basket with 4×4 diagonal
USED ON WIDE OVERHANG OR DEEP GIRDER APPLICATIONS
No Hanger Required * Single Bolt * Fully Adjustable * Minimum Deflection
80 inch Standard and an Optional 60 inch model
- 80” bracket comes with three saddle positions located at 1’, 4’-6”, & 6’. There are two locations to install the swivel bracket for the 4 x 4 diagonal. weights = 95 pounds
- 60” comes with two saddle positions located at 1’ and 4’-0” weights = 84 pounds
- It will work “either side up” so you have a choice of having the attachment bolt hole:
- 8.5” up from horizontal top surface, usually a steel girder bridge
- 3.5” up from horizontal top surface usually a concrete girder bridge
Facts about the 8 kip Bracket
- CAN BE USED WITH BOTH PRECAST CONCRETE AND/OR STEEL GIRDERS.
- Brackets are designed & tested to carry a working load of 8,000 lbs. with a safety factor of 2.5 to 1.
- Tests for ultimate loading was performed on two brackets;
- First bracket was loaded to 58,300 lbs
- Second bracket was loaded to 63,600 lbs
- Both loads failed on the 4 x 4, which broke in the middle
- These brackets have been approved for use by Washington DOT, Caltrans DOT, Idaho DOT, Oregon DOT, and Nevada DOT
- In normal use, the deflection at the location of the outer screw jack is 1/8” at 8,000 lbs. 4 x 4 must be bearing firmly on both ends. Do not use 4 x 4 with big knots. Use #1 grade.
- The 7/8” single A325 bolt through the web anchors the bracket for any outward movements and resists rotation.
- The angle of the diagonal can be changed to bear the 4 x 4 firmly onto the bottom flange of the beam.
- Furnished with two saddle jacks, 4 x 4 attachment and four wing-nuts.

“The new bridge will feature 5-foot shoulders, a 12-foot pedestrian walkway to improve safety and a new roundabout in Manette that will enhance the flow of traffic between here and Bremerton,” said Paula Hammond, Secretary of Transportation. “Thanks to input and support from the communities of Bremerton and Manette, we have developed a design that better serves travelers, and keeps with the historical flavor of this area.”

Project Benefits
- Improved structure. The new bridge will be designed and built to current engineering standards
- Safety. Wider shoulders and sidewalks enhance bicycle and pedestrian mobility.
