Transit Infrastructure: The Latest Architecture and News

Greenways, as a typology of urban design, have become an essential element in the planning of modern cities. They emerge in response to the increasing fragmentation of urban landscapes by elements such as highways. They usually integrate natural and constructed spaces, providing much-needed connections across various parts of the city. At the same time, they promote pedestrian accessibility, recreation, and social interaction. The Rose Kennedy Greenway in downtown Boston, United States, exemplifies this human-centered approach to design. The project, which began construction in 1991, showcases the potential of greenways to reconnect urban environments and enhance community life. As a series of parks designed by various architecture firms, it aims to create physical links and meaningful spaces that foster social development and a sense of place.

Traveling on land through vast regional areas of African countries has been an inefficient ordeal, particularly in West Africa. Google Maps optimistically estimates it would take 53 hours to drive nonstop from Lagos, Nigeria's largest city, to Dakar, Senegal's capital. However, this estimate doesn't account for the poor road infrastructure, complex border crossings, and socio-economic challenges that realistically extend the journey to about a week.

This is why the ongoing Trans-West African Coastal Highway project offers a great opportunity to connect and unlock the region's potential. This project, also known as TAH 7, is a transnational highway initiative linking 12 West African coastal nations, from Mauritania in the northwest to Nigeria in the east. Its gradual construction opens new avenues for freight movement, rail infrastructure, and, more importantly, innovative forms of architecture around borders, addressing their unique socio-cultural functions.

Eastern and Southern Europe is enduring a severe heatwave, with temperatures reaching over 40 degrees Celsius in many countries including Greece, Croatia, Macedonia, and Romania. Driven by hot air from North Africa, this prolonged heatwave has raised significant threats for residents and has strained the cities’ mechanisms for protection and climate mitigation. As the heatwaves expose the vulnerabilities of urban infrastructures, cities across Europe are striving to implement measures to address these challenges.

URB has revealed details about the Dubai Green Spine project, an urban development initiative aiming to introduce a 64-kilometer-long green corridor in Dubai. The project, aligned with the Dubai 2040 Urban Master Plan, hopes to improve urban mobility and environmental quality by converting one of the city’s major arterial roads into a multifunctional public space with ample greenery, urban farms, integrated non-motorized transportation infrastructures, and community zones.

As part of public ‘open house’ sessions with local communities and agencies, Foster + Partners and Arup have revealed the design for the first 4 stations of California’s High-Speed Rail. This is part of an extensive project, as the new Central Valley stations will serve as models for the design of the next stations planned along the 500-mile-long Los Angeles/Anaheim to San Francisco rail system. The open house sessions represent an opportunity for the public to explore the project, talk with California High-Speed Rail Authority planning experts, and learn more about the high-speed rail infrastructure. The project is under construction, with the first operable line scheduled to be completed between 2030 and 2033.

SITELAB urban studio and Field Operations have revealed a design proposal to reimagine San Francisco’s iconic Powell Street. The street used to be one of the busiest pedestrian corridors in its district and a popular tourist attraction, with cable cars running up and down the street and connecting Union Square and Hallidie Plaza. Across the most popular three-block stretch, the storefronts have become mostly vacant. According to the San Francisco Chronicle, one of the reasons was the Covid pandemic, which led to a further decrease in tourism and in commercial activities. Now a new project led by designers SITELAB urban studio and Field Operations aims to revive the now underutilized transit corridor and to catalyze a renewed interest in the area.
