Reconnecting East Harlem to the heart of New York City🍎
Phase 2 of NYC’s legendary Second Avenue Subway is officially on track - and we’re leading the design.
Here’s what’s in store: ✨ $1.972B investment in the city ✨ Extending the Q Line from 96th ➡️ 125th Street ✨ 1.5 miles of twin tunnels ✨ 3 brand-new ADA-accessible stations ✨ Fresh station shells + new community & retail spaces above ground
The impact? Less congestion. Faster, smoother commutes for 100,000+ daily riders. A city that feels even more connected.

Have you heard about Karlatornet, Gothenburg's one and only skyscraper? 🏙️ The design of Karlatornet is highly efficient in terms of floor space and energy usage, while still including apartments with views focused on the city and waterfront. Beyond its individual appeal, Karlatornet contributes to a vision for the entire area, bolstering the overall allure of Gothenburg, especially the post-industrial business district north of Götaälven.
In 2014, COWI was part of the team which won the architecture competition for Karlastaden, and COWI has continued to provide various technical services at different stages for the spectacular and exciting urban development project. @arkitema has contributed with construction documents and more than 600 drawings to the project.
