Hoyle, Tanner provides transportation engineering services to numerous federal, state, municipal and private clients throughout New England, Florida and the Virgin Islands to meet the specific needs of minor and complex projects effectively and efficiently. Our ability to maneuver clients through the roadway design from the initial concept to construction completion allows us to serve as an extension of their staff.

Some of our state and federal clients include: New Hampshire Department of Transportation (NHDOT), Vermont Agency of Transportation (VTrans), Massachusetts Department of Transportation (MassDOT), Government of the U.S. Virgin Islands (USVI), and Veterans Administration (VA).

We work with our clients to formulate innovative design solutions where regulatory constraints merge with functional requirements. Our roadway engineers account for future traffic flows in the design of roadway intersections/interchanges, geometric alignment, and pavement materials, thickness and maintenance. Our designs incorporate sustainable transportation infrastructure into projects focused on solving safety concerns, vehicular congestion, and environmental and economic issues. Project deliverables are prepared in accordance with the Federal Highway Administration (FHWA), Federal Aviation Administration (FAA), Army Corp of Engineer (ACOE), National Environmental Policy Act (NEPA) and state agency requirements.
