Pacific Northwest

In our early years Hamilton was one of many small contractors in Oregon providing small bridge and highway work; today Hamilton’s core division is one of the Northwest’s largest, tackling the most complex jobs throughout the Pacific Northwest. We have built over 300 bridges in Oregon and Washington alone. Hamilton has the experience, equipment, capacity and people to do quality work, on time and on budget.
