The Crystal City Metro Station East Entrance has become the first public transportation station project in the Mid-Atlantic to earn Envision Silver.

The project has been designed to:

👥 increase station capacity,
🚶 accommodate more riders,
♿🛡️ improve accessibility and safety, and
🔀 enhance connectivity as the area continues to grow.

The station is part of the Washington Metropolitan Area Transit Authority (WMATA) public transit system and one of the busiest stations in Arlington County, Virginia, just outside Washington, DC.

📋 Background

The County’s station sector plan identified the need to improve access and address congestion. Over the years, further evaluation and stakeholder feedback helped to narrow potential sites and shape the final above-ground entrance design.

📍 Location and key features

Located at the northwest corner of 18th Street South and Crystal Drive, the new entrance provides street-level access through an above-ground lobby and connect passengers to the train platforms via a new mezzanine, stairs and elevators.

🤝 How it came together

WMATA and Arlington County teamed up with local developer JBG Smith, lead designer VHB, and Clark Construction to deliver the project through a collaborative design-build approach. The project broke ground in July 2024. VHB also led the Envision verification effort, coordinating sustainability and design strategies through multiple phases and guiding the project using the Envision framework.

📢 The Avenida Longitudinal de Occidente – Tramo Sur Project has been verified Envision Platinum!

This project was designed to alleviate congestion on the freight and arterial corridors serving the city of Bogotá, Colombia. A bidirectional north-south highway, the project will connect to the Autopista Sur (Southern Highway) in the Muña (Chusacá) area of Sibaté and extend 24.5 km (15.2 miles) to Calle 13 in Bogotá. The project team planned and designed the project as an integrated response to the region’s infrastructure deficit and its interconnected mobility, social and environmental challenges.

Here are a few of the sustainable infrastructure achievements on this project:

🚦 Reduction of gridlock, improved traffic flow, and increased public safety;
🌬️ Mitigation of air quality and noise impacts;
🚶 The addition of a metropolitan-scale active transportation network (e.g., connecting the El Porvenir Promenade with the Bogotá River Promenade);
📈 Enhancing economic growth through improved connections along a vital logistics corridor and job creation during the construction phase;
🏛️ Returning the abandoned Canoas Archaeological Park to community use; and
💧 Significant measures to protect surface water and groundwater quality.

Juan Carlos Guevara, Project Manager, noted: Planning the infrastructure with its lifecycle in mind allowed us to consolidate a connectivity model that balances climate resilience, social well-being, and resource efficiency. This achievement positions us as a Latin American benchmark in sustainable infrastructure and drives us to continue proving that the engineering of the future must be environmentally responsible and socially transformative.”
