Inman Square is a vibrant commercial and residential area with a roadway network that serves high volumes of people who walk, bike, ride transit, and drive. As part of a multi-disciplinary team, McMahon led the transportation analysis and design for the Inman Square Intersection Safety Improvements Project. The design challenge was the existing unusual geometry of a severe skew of the primary intersection, high number of intersecting streets that cause safety and operational challenges for all users and maintaining emergency access to a fire station. McMahon’s role was to develop solutions to address the size and complexity of the intersection, which is challenging for bicyclists and drivers, while pedestrians currently face long delays waiting to safely cross.


The purpose of the project was to develop multimodal safety improvements by:

  • Providing sidewalk-level, separated bicycle lanes, protected intersection treatments, and improved pedestrian facilities;

  • Improving and simplifying operations for all modes;

  • Designing bus stops;

  • Providing for on-street parking and loading;

  • Continuing to support the local, residential and business communities that define Inman Square.


McMahon was a leading team member for the entirety of the project from initial visioning and alternatives development, to preliminary and final design plans, and assisting with bidding for construction for this high profile, Vision Zero project. This project is currently in construction with McMahon providing construction phase services.
