Highway Engineering

GRA has conducted conceptual and final design for hundreds of highway projects. The scope of these assignments ranges from multi-million dollar highway construction and reconstruction projects to simple plat streets. From low-volume rural roads to busy urban highways to major freeways, GRA has developed design concepts that successfully meet the project requirements, yet are sensitive to the surrounding environment.

GRA's many roadway design assignments have been conducted for the Rhode Island Department of Transportation (RIDOT), the Massachusetts Department of Transportation (MassDOT) and other state and municipal government agencies. All of these projects have been accomplished to meet both state and federal design standards. GRA has the expertise necessary to conduct all of the initial studies and investigations, development and evaluation of alternatives, conceptual analysis and design, public participation, and the assessment of potential environmental impacts and permitting requirements. Once the conceptual studies are complete and a preferred alternative has been selected, GRA's experienced engineers lead their teams in the final design tasks and the preparation of the plans, specifications and estimates required to advance the projects to construction. GRA's staff is trained and experienced in producing Context Sensitive Solutions on our highway design assignments.
