It’s astounding how many integrated parts make up our transportation systems — from roadways, highways, runways, and railways to massive bridges and tunnels. No longer is a lake, bay, swamp, or mountain an obstacle between people and their destinations — not with the extraordinary feats of transportation engineering possible today.

Transportation engineering is one of RETTEW’s fortes. For decades, we’ve helped connect people to places. We partner with federal, state, and local governments, turnpike commissions, departments of transportation, transit agencies, river and port authorities, airports, and other clients to find cost-effective, efficient, and innovative traffic and transportation solutions. We’re also known for our teamwork with contractors and fabricators to move projects forward and facilitate effective plans. We handle everything from traffic studies and environmental investigations to design and inspection.

Aging infrastructure, dwindling budgets, and increased populations pose many challenges to maintaining and expanding our transportation infrastructure. New residential and commercial developments can put stress on existing traffic patterns, bridges continue to deteriorate, and highways need constant maintenance to handle heavy traffic. Our transportation consultants help clients determine if a road, bridge, or other structure is in need of repair, rehabilitation, or replacement — keeping overall regional transportation strategy, budget, and time constraints top of mind.

The visionary team at RETTEW is attuned to emerging trends in the transportation industry, such as adaptive traffic signals and autonomous vehicles. We’ll help you navigate how new technologies and cultural shifts — such as self-driving cars becoming a reality—will affect your goals and projects now and in the future.

Our keen understanding of current regulations and well-established relationships with the Federal Highway Administration, state departments of transportation, environmental regulators, and local- and state-level agencies allow our projects to move forward with the fewest bumps in the road.

It’s more than roads.

Many cities and towns have a renewed focus on walkability and wellness; encouraging citizens to walk or bike to work means creating safe sidewalks, crosswalks, and biking lanes. And a big part of urban renewal is creating pleasing streetscapes, an opportunity for transportation and design to merge.

At RETTEW, we also think big picture. We consider how our residents may interact with other transportation options, such as city buses or regional train lines. This means transportation engineering also involves developing strategic partnerships between highway owners and transit operators—it’s important to consider mutual needs as we develop long-term projects.

From small country roads to busy city streets and interstate highways, our nation’s transportation infrastructure is massive and in constant need of attention. Transportation engineers — like the experts at RETTEW — are the driving force behind successful design, construction, operation, maintenance, and management of these complex systems.
