Drawing on more than 50 years of experience, Nicholas O'Dwyer plans, designs and manages the construction and operation of the highways of tomorrow. 

We provide a full range of services to help transportation agencies meet the financial, technical and contextual challenges of delivering roads and highways that address the economic, social and environmental needs of the communities they serve.  Our professional staff have devised solutions for projects of all scopes, sizes, and levels of complexity. We encourage innovation across disciplines and collaboration with clients and stakeholders to develop outcomes that are as sustainable for tomorrow as they are successful for today. 

We provide services in every aspect of a highway program including transportation planning, traffic analysis, urban design, environmental impact studies and statements, funding and feasibility analysis, preliminary engineering, final design and construction supervision.
