Nairobi’s Growing Transit Challenges and Past Efforts
Nairobi has faced persistent traffic congestion issues for years, often ranking among the most congested cities globally. The city’s population continues to grow rapidly, increasing demand for efficient public transportation.
Previous efforts to improve transit have included expanding road networks, introducing bus rapid transit (BRT) systems, and upgrading existing rail lines. However, these measures have not fully alleviated congestion, prompting the need for more comprehensive solutions like underground transit.
The idea of an underground rail line has been discussed for several years, with preliminary feasibility studies conducted in the past. The recent approval indicates a shift from planning to actual implementation phases.
