Whether overcoming traffic congestion in an urban corridor through innovative intelligent transportation system solutions, designing new bridges, or evaluating roadway safety for bicyclists and pedestrians, our transportation engineers work together with our clients and the community to develop sustainable designs that meet the needs of the travelling public and improve the environment.

SLR offers a broad range of services in the area of transportation engineering and design.

How can we help?

Our transportation engineering team has a stellar reputation in the industry and have worked on many successful public and private sector projects, utilising innovative approaches and cutting-edge tools.

Our goal on every project is to enhance mobility for all travel modes without compromising safety or adversely impacting the environment. Whether widening a highway, enhancing operations along a signalised corridor, or rehabilitating a historic bridge, we achieve success by engaging project stakeholders and partnering with regulatory agencies, ensuring compatibility among transportation facilities, the surrounding environment, and the community.

We provide expertise in several areas including, highway design, interchange planning and design, bridge design, rehabilitation and replacements, bicycle-pedestrian facility planning and design, adaptive traffic signals, transportation communication systems and intelligent transportation systems.

  • Gregory Blake Principal Transportation Engineer
    Gregory Blake

    Gregory Blake is a Principal Transportation Engineer with over 35 years of experience working on a wide range of civic and transportation engineering projects for municipal and private clients. His experience includes the design and management of a broad scope and scale of infrastructure projects (from complex highway interchanges to rail trails and pedestrian facilities) for transportation agencies throughout New England. After receiving his degree in Civil Engineering, Greg joined the U.S. Air Force and Air National Guard, where he served honourably for over 20 years. During that time, he also served as a member of multiple national engineering organisations including as the Maine Chapter President of the American Society of Civil Engineers. He presently sits on Massport’s Designer Selection Panel, assisting with consultant selection on a wide variety of Capital Improvement projects. With his skills in project design and management, quality assurance and control, and client relationship management, Greg brings a focused and collaborative approach to transportation engineering services at SLR.

  • Michael Zarba Principal Transportation Engineer
    Michael Zarba

    Mr. Zarba is a principal transportation engineer with over 30 years of public and private sector experience and leads the team’s engineering and project delivery efforts in northern New England. As a former director of public works, he brings extensive design, management, and administrative work experience to SLR. Additionally, Mr. Zarba has a wealth of knowledge in the design and construction of complex transportation projects as well as the maintenance and administration of public infrastructure involving highway and sidewalk design, building and facility maintenance, drainage, bridges, and municipal infrastructure capital improvement planning. He also maintains a close connection to our construction engineering and inspection teams to effectively complete roadway, bridge, utility, and facility type projects.

  • Shelley Plude Senior Structural Engineer
    Shelley Plude

    Shelley serves as the bridge design lead within the transportation engineering group and is responsible for performing designs for a wide range of structures, in addition to bridge load ratings for bridge projects. She also handles the development of plans, specifications, and estimates as well as day-to-day project management and client/liaison coordination. Due to the interdisciplinary approach taken toward each project, she often works with engineers of different disciplines, from geotechnical to water resources, to examine how a structure will work with its surroundings. With a lifelong interest in math and science, structural engineering was a natural fit for Shelley, to blend her technical interests with creativity and problem-solving.
