US 101 Siuslaw River Bridge 

​Location: Florence, Oregon
Client: Oregon Department of Transportation
Start Date: 2015
End Date: 2019
As General contractor on this project, Hamilton’s main scope of work is to install a cathodic protection system on the approach and tied arch spans of this bridge which spans the Siuslaw River on US101 in Florence, OR. Hamilton first began the renovation of this structure in 2009 when we made extensive upgrades to the mechanical lift system. In addition to cathodic protection, work also includes replacement of the exiting ornamental bridge rail, installation of seismic restrainers and replacement of the existing bearings.

 I-5 Portland Avenue to Port of Tacoma 

​Location: Pierce County, Washington
Client: Washington Department of Transportation
Start Date: 2015
End Date: 2018
Just north of the Tacoma Dome, this $134 million project widens I-5 from Portland Avenue to the Port of Tacoma Road to provide room for a new HOV lane in each direction and four general-purpose lanes in each direction. Working with the Washington Dept. of Transportation, Hamilton will rebuild the I-5 Puyallup River bridge, reconstruct the I-5/SR 167 interchange, improve the Portland Avenue interchange and repave all the lanes on I-5 within the project limits.
This project will provide a number of benefits to motorists: Improved safety, seismic upgrades, improved traffic flow, environmental improvements, and an Intelligent Transportation System (ITS) upgrade which will allow WSDOT to respond more quickly to highway incidents and reduce traffic delays.
As General Contractor on the project, Hamilton’s work includes the construction of a nine span (1,600′ long x 100′ wide) precast girder bridge across the Puyallup River, as well as a four span (820′ long x 40′ wide) curved steel plate girder bridge for a new NB off ramp. Bridges are founded on 8-10′ diameter drilled shafts, cast-in-place (CIP) columns and X-Beams. Thirty spans of work bridge will be required to access the river bents, as well as major shoring required on the levees of the river. Other structural work includes 23 retaining walls of various types, deck repair, joints, end panel replacements on two existing I-5 bridges, three sign bridges, four cantilever signs, as well as deep 60 and 72″ storm sewer replacement with major shoring and CIP encasement work. Ground improvement work includes stone columns, cement deep soil mixing (CDSM), Jet Grout, Micropiles, lightweight fill, and embankment grouting along with an elaborate settlement monitoring system. Other work includes a large civil package, electrical, signing, asphalt and concrete paving, etc. as well as a major traffic control effort on a very congested section of I-5.

 US 101 McCullough Rehab North Approach

​Location: North Bend, Oregon
Client: Oregon Department of Transportation
Start Date: 2013
End Date: 2018
The rehabilitation of the 77-year old Conde McCullough Memorial Bridge has entered its second phase and once again, Hamilton Construction has been selected to help preserve this coastal treasure. (Hamilton recently completed a six year rehabilitation of the south approach of the bridge.) North approach work includes cathodic protection, concrete repair, bearing replacements, bridge drain retrofits, and seismic restraints. Hamilton will also construct 38 spans of work bridge along with structural support for the cathodic protection work enclosure. 
​Cathodic protection: reduces saltwater-induced corrosion of bridge reinforcement steel by electrochemically “re-directing” the corrosive oxidation reaction to an applied surface coating of zinc.

Broadway Bridge Repair, Rall Wheel CMGC 

​Location: Portland, Oregon
Client: Oregon Department of Transportation
Start Date: October 2016
End Date: Late Fall 2017
Hamilton is the Construction Management/General Contractor teamed with Multnomah County and Hardesty Hanover engineers to design, replace and repair elements of the draw bridge mechanism on this 103-year old structure. The most challenging part of the project will be the replacement of the massive 7,000 lb. rall wheel. This wheel enables the draw bridge to open up and roll back. In service since 1912, both the wheel and its track have become worn and pitted, creating concerns it could jam or come off the track. Safety and minimizing inconvenience to the public are top priorities on this project given its downtown location and heavy use by cars, pedestrians and bicyclists.

I-5 Willamette River Bridge

​Location: Eugene/Springfield, Oregon
Client: Oregon Department of Transportation
Start Date: 2009
End Date: ​2013
Hamilton was the Construction Manager/General Contractor (CM/GC) on ODOT's first CM/GC effort and the agency’s largest project to date. This $148 million project involved replacing an existing bridge with two new uniquely designed twin arch bridges and constructing a pedestrian/bike bridge in the midst of a sensitive habitat area with heavy recreational usage and a high volume of autos, rail, bicycle, and pedestrian traffic. The new bridge spans the Willamette River, a four-lane highway, and a UP mainline. Each of the new structures are approximately 1800-feet long and feature a combination of deck arch and cast-in-place box girder spans.

Demolition included: six 143-foot main spans of cast-in-place concrete box girders over the Willamette River; the reinforced concrete deck girder spans and a steel girder span in the approach structures; removal of 116,000+ sf of precast box beams, 2500+ lf of bulb-T girders with composite deck; and 1800 lf of steel plate girders with composite deck, concrete cap beams, concrete columns, and drilled shaft foundations.

The project required complex arch falsework design and construction, extensive shoring, 140,000 sf of temporary work bridge, and many innovative solutions. Due to the high quantity of rebar in the footings, Hamilton worked with the ready-mix concrete supplier and owner to develop a site specific Self Consolidating Concrete (SCC) mix design. Work access for the majority of construction was via a Hamilton constructed work bridge.
This project opened to traffic four months ahead of schedule, $15 million under budget, and was named Best Construction Project in the Pacific Northwest for 2014 by Engineering News Record.
