Transportation Design

Innovative and Methodical Approach

CBB’s roadway, traffic signal, ITS, and lighting designers take an innovative and methodical approach to solving design challenges by understanding the fundamental needs of the project. We provide design services for both public and private clients, including DOTs, jurisdictions, and developers.

Each Project is Unique

The projects we complete range in size from interchanges to turn lanes and driveways. Each project is a unique assignment, and we strive to develop alternatives that minimize impacts and construction costs while maximizing safety and functionality.

Our Design Process

We are committed to detail and coordination in our design process. We are well versed in completing high-level concept plans to final design plans for construction. We have been involved in high-level planning studies, design-bid-build projects, and design-build projects. We are adaptable to last minute changes that are inevitable during construction as well as finding ways to cut costs without sacrificing quality. CBB has years of expertise in a wide range of design experience including complex intersections and interchanges, roundabouts, traffic signals, lighting, and Intelligent Transportation Systems (ITS).

Skilled Staff

Our staff is also skilled in the latest versions of powerful software tools such as AutoCAD Civil 3D, MicroStation and Autoturn. We also provide construction review and inspection services, which allows for a seamless transition from the project design phase to final implementation. At CBB, we are passionate about providing accurate and well-designed plans and are committed to accomplishing our client’s goals within the required budget.
