Modern Solutions for Now and the Future

Well-designed transportation systems are the backbones of our communities. This is especially true in high-growth areas that need to expand or enhance their roadway networks to better serve residents and visitors. In the western United States, this applies not only to urban areas that need interchanges or other expansion projects but also to aging bridges and roads in more rural areas.

Morrison-Maierle’s founders started our firm more than 75 years ago with the idea that communities could be transformed by modern transportation systems. As you meet and work with our team, you’ll see that our focus hasn’t changed.

From modern bridges to large highway systems to rural roadways, we still focus on getting the job done right the first time. Whether you’re looking to boost economic development with a large infrastructure project or provide a way for outdoor enthusiasts to access adventure—our engineers will help you create solutions that enhance your community’s desire to move and grow.
