The Eglinton Crosstown LRT, also known as Line 5 Eglinton, is Toronto's most significant transit expansion project in decades, requiring innovative solutions to address its scale, complexity, and impact. Spanning 19 kilometers east to west, it has 25 stations (15 belowground and 10 at-grade), including three interchange stations, a maintenance and storage facility, and significant utility infrastructure and public infrastructure improvements. Coordinating these elements within an existing urban fabric posed significant logistical, design, and engineering challenges.

One of the primary considerations for the Eglinton Crosstown LRT is the passenger experience. The project required a context-sensitive, system-wide design to create well-connected, high-capacity stations that cater to diverse communities and are easy to navigate. Beyond operational challenges, Line 5 aims to act as a catalyst for urban intensification and civic improvement along the Eglinton corridor, fostering enhanced connectivity and contributing to the city's overall growth. 

Arcadis led the system-wide architecture, interior design, and urban planning, and provided full detailed engineering services and construction support for several above- and below-ground stops, developed a traffic and transit management plan, and managed the project’s design and engineering in a joint venture with AtkinsRealis as a part of the Crosslinx Transit Solutions Design consortium.
