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.
In 1939, a wire suspension bridge measuring 245 feet in overall length was built over the South Fork of the American River on Mosquito Road. The bridge is a 9-foot wide, one-lane limited capacity timber suspension bridge with a 140-foot long span. Portland Bolt was contacted by the County of El Dorado about manufacturing the bolts required in the rehabilitation of the Mosquito Bridge. The list of required fasteners was a mix of long rods, 7/8” in diameter in lengths up to 88” and headed bolts ranging from 1/2” diameter to 3/4”, all meeting the ASTM A449 specification. Needless to say, they were anything but standard. The fastener requirements also included A307 Grade A Timber bolts and A36 square plates which Portland Bolt fabricated in-house. Read more...

In January of 2013, Portland Bolt supplied shear plates, split rings, long galvanized threaded rods, hex bolts, lag screws, and lock nuts for the Bishop Road Bridge project in Portneuf, Quebec. Portnuef is a small town that is about 36 miles outside of Quebec City. Portland Bolt manufactured these items on a standard lead time of two weeks and packaged them for travel across the continent to Quebec. The 22 foot wide, 125 foot long new bridge traverses the Portneuf River, which is a tributary of the Lawrence River and carries the traffic of the roughly 3,000 residents of Portneuf on Bishop road.

In the summer of 2010, rehabilitation work on the OR 43, Oregon City / West Linn Arch Bridge began. This historic bridge has spanned the Willamette River since 1922. After 88 years of use, the bridge was in great need of repair. For safety purposes, Oregon Department of Transportation closed the bridge down for approximately two years to be reopened towards the end of 2012. The extent of the repairs needed is due to corrosion of the underlying steel structure, damaged railings and the need to resurface the bridge deck. It has been estimated that more than 13,500 vehicles as well as 200 to 300 bicyclists and walkers cross the bridge each day. Needless to say, the rehabilitation and re-opening of this bridge is highly anticipated. Read more...

In July of 2012, Portland Bolt came to the aid of the contractor constructing a new pedestrian skybridge in downtown Seattle, Washington. The skybridge spans the alley between 5th and 6th Avenues. The area is known locally as “Jazz Alley” because for decades it has been the location of one of the West Coast’s premier jazz clubs. The job required multiple tie rod assemblies for the erection of the skybridge. Because the project required closing down the street completely to all traffic during the erection of the skybridge components with a crane, there was a very narrow window of delivery required.
The particular circumstances of this job required Portland Bolt to not only manufacture the tie rod assemblies quickly and correctly, but to also have the tie rod assemblies specially delivered to the jobsite on a flatbed trailer before 8:00 AM the following Monday in order for the contractor to use a crane to lift them into place and re-open the street on schedule. Portland Bolt was able to arrange this special delivery and have the tie rods waiting on site at 5:00 AM when the fabrication crew arrived. Consequently, the contractor was able to complete the project on schedule. From the time of the contractor’s first call to Portland Bolt until the tie rods were delivered on site fully assembled and ready for installation was only 6 working days! Read more...

The Oro Dell Bridge is located approximately two miles west of La Grande, Oregon in Union County. Oregon Department of Transportation identified the need for major repairs and preservation performed on the bridge in order to maintain the continued use of the structure.
The project was estimated to start in the spring or summer of 2011 and had an estimated completion date of late 2011. This project had a contract cost of approximately $2.5 million dollars through the Statewide Transportation Improvement Program, which was on the state’s priority list for bridge repair work at the time. The highway contractor in charge of performing the repairs contacted Portland Bolt due to the large quantity of domestically made, custom fasteners required as well as all of the fasteners needing to be hot-dip galvanized.
Portland Bolt is regularly involved in Department of Transportation bridge projects due to our bolts being domestically manufactured here in house in addition to the hot-dip galvanizing. In total, Portland Bolt provided approximately 20,000 pounds of custom anchor bolts. Read more...

In May of 2012, Portland Bolt supplied the galvanized hardware for a new pedestrian bridge in Milwaukee, Wisconsin. The 96 foot long, 23 foot tall, 36,000 pound bridge connects the playing fields behind Riverside High School with the trails that wind through Riverside Park. The new pedestrian bridge was installed over the Oak Leaf Trail. This bridge is part of a park access plan created by the Urban Ecology Center, Milwaukee County Parks and other community stakeholders and is incorporated into the Rotary Centennial Arboretum scheduled to open in Fall 2013.
One of the strict requirements of this project was that all product per specifications had to be fully domestic. Portland Bolt supplied 414 galvanized headed bolts, 36 galvanized rods, 596 galvanized square plates, along with all the corresponding nuts and washers, which amounted to 3,600 pounds of domestic hardware. All product, aside from the nuts and standard round washers, were manufactured in Portland Bolt’s 85,000 square-foot facility including the galvanizing and plate fabrication, showing once again the capabilities that Portland Bolt brings to the market.

In April of 2012, Portland Bolt was selected to provide bolts for the Overpeck County Park Bridge in New Jersey. This wooden bridge will serve both pedestrians and automobiles.
Portland Bolt provided approximately 30,000 lbs of bolts for this project, including timber bolts from 1⁄2" to 11⁄4" diameter, hex bolts, lag bolts up to 1" diameter, and 2" diameter drift pins. The majority of the bolts were hot-dip galvanized in our facility, and all of the bolts were required to be 100% domestic with full certification and traceability. Read more...

The Murray Morgan Bridge was built in 1913 in Tacoma, Washington. It is known for its remarkable deck height and is on the National Register of Historic Places and the State Heritage Register. Concerns of safety closed the bridge in 2007. It is undergoing an extensive rehabilitation and Portland Bolt was chosen to provide the unusually long rods and coupling nuts for this project. All product was required to be 100% domestic on this federally funded project. With an aggressive schedule using long galvanized F1554 grade 55 rods, Portland Bolt was chosen for our reliability of quality and shipping on time. We supplied over 75,000 pounds of 21⁄2” diameter galvanized F1554 grade 55 rods with nuts, coupling nuts, and sleeve nuts. The lengths varied from 130” to 240” long. Our partnership with steel mills allowed us to receive a special steel rolling in time to meet our schedule. Portland Bolt’s 85,000 square foot manufacturing and galvanizing facility is equipped with multiple overhead cranes. This allowed us to easily handle these rods weighing as much as 330 pounds each.
