Bridge Projects
Portland Bolt manufactures a variety of domestic anchor bolts and high strength fasteners for the construction of new bridge projects and the retrofitting of existing bridges. The majority of these projects require hot-dip galvanized products and are often federally funded state DOT jobs requiring 100% domestic product.
Sauvie Island Bridge - Portland, OR
Located approximately 10 miles west of Portland, Oregon the only bridge providing access to Sauvie Island was in need of being replaced. The original concrete girder bridge was built in 1950 and quickly deteriorating. Construction started in December of 2007 to replace it with a 1,177 foot long tied arch structure. At $42 million bridge features over 1,250 tons of weathering steel.
Portland Bolt worked with the local steel fabricator to supply some of the fasteners for this bridge.
New Bay Bridge Skyway Project - Oakland, CA
A portion of the extensive San Francisco-Oakland Bay Bridge project has been completed. This billion dollar job extends from Oakland, California west towards San Francisco. The structure was built parallel to the existing Bay Bridge. At over a mile long it contains approximately 200 million pounds of structural steel. The Oakland Skyway will connect to the new self-anchored suspension span currently under construction.
In May 2003, Portland Bolt sent its first shipment of material to Kiewit/FCI/Manson the joint venture in charge of the project. Some of the domestic bolts manufactured for this project included large 2-1/4 inch diameter heavy hex bolts used for the initial assembly. Specially designed stainless steel bolts were required for the fender systems located at water level were supplied in October 2007. To meet the demanding requires of the environment, additional steps were specified to ensure the highest level of corrosion resistance.
New Tacoma Narrows Bridge - Tacoma, WA
In the fall of 2002, after five years of politics and planning, Tacoma Narrows Constructors started on the New Tacoma Narrows Bridge. This 5,400 foot long suspension bridge, $849 million, was a joint venture between Bechtel and Kiewit. Seven years later, the first passenger vehicles drove across in July 2007. This massive structure stands parallel to the original Tacoma Narrows Bridge. The goal of the new bridge was to provide safer crossing and reduce congestion for people traveling in the Puget Sound area.
This massive bridge contains 35.5 million pounds of structural steel and numerous bolted connections. Over a three year period Portland Bolt was asked to supply a variety of construction fasteners. Products manufactured for the this job included bolts for the saddle supports, main span bolts that included 2-1/4” ASTM A449 anchor rods, and large 1-1/2” diameter A325 heavy hex structural bolts delivered in one day.
Rhythm City Skybridge – Davenport, IA
Portland Bolt secured a contract to manufacture 85,000 pounds of 4” and 4-1/2” diameter A572 grade 50 structural hanger rods measuring up to 68’ in length for the Rhythm City Skybridge.
As part of Davenport, Iowa’s downtown redevelopment, the Rhythm City Skybridge connects a plaza in the 100 block of West 2nd Street with the front of the Rhythm City Riverboat Casino.
