Project Summary

Lynn Street is at the heart of a major regional crossroads. Reconstructing this street meant taking on the challenges of crossing a capped interstate freeway and an underground Metrorail line while the surface street itself carries tens of thousands of commuters in cars and buses, as well as bicyclists and pedestrians on a major regional trail. We re-envisioned Lynn Street as a world-class, multimodal corridor, taking this project from the concept phase through final design and construction.

The project reconstructed an existing bridge over I-66 to transform the structure and its surroundings. New elements include widened sidewalks, an expanded multiuse path, street trees, LED streetlights, planting areas, public art, crosswalk improvements, widened trails, bike lanes, signal and sign improvements, and safer intersections. Throughout the planning and design process we coordinated with numerous national, state, and local agencies and stakeholders. Proper design and construction of the Esplanade also required extensive coordination with a wide variety of engineering disciplines and technical specialists, as well as a project artist.

Completed in 2020, the corridor has reconnected downtown Arlington to the Potomac River waterfront and is an inviting pedestrian environment that has improved multimodal safety while maintaining efficient movement of traffic.


Lynn Street now includes safer intersections throughout for people walking and biking.
The structural engineering for this project was particularly complex due to the need to expand the existing structure and incorporate several artistic curved retaining walls that align the Esplanade and connect to existing support walls.
Coordination efforts with the geotechnical engineer, public artist, landscape architects, and roadway engineer were key to creating a corridor that is safer, more functional, and more beautiful.
