Walking remains the most common form of transit for a significant portion of GLMZ's population, and the pedestrian infrastructure of the city is among the most legible expressions of its social hierarchy. The elevated walkway networks of the mid-tier and upper-tier districts — called Skywalks in common usage — are climate-controlled, surveilled, and maintained to a standard that reflects their function as extensions of corporate commercial space. The Skywalk system connects approximately 340 major commercial and residential towers in the mid-tier districts, allowing Tier-One and Tier-Two residents to move between destinations without descending to street level. Access to Skywalk segments is gated by citizenship verification at each major junction; Tier-Three residents may access designated segments during business hours but are excluded from residential connector sections after 2200.

At street level, the experience of walking varies enormously by district. In the corporate-managed commercial districts of Portsmith, Caldor Heights, and the Harmon Plateau approaches, street-level pedestrian infrastructure is maintained, lit, and monitored. Surveillance density in these areas is among the highest in the megacity — mesh-node facial recognition, gait analysis sensors, and neural-passive scanning arrays cover effectively 100 percent of public space. The walk from the Portsmith Spine Station to the Caldor Tower complex is a journey through a continuous surveillance envelope that logs identity, movement patterns, and, for those with registered neural interfaces, ambient cognitive-emotional metadata. This data is retained and sold; its primary purchasers are commercial targeting platforms and corporate security services.

In lower-tier and sub-street areas, the pedestrian infrastructure tells a different story. Ground-level streets in Tier-Three residential districts are nominally maintained under city infrastructure contracts but receive a maintenance budget approximately one-seventh of that allocated to commercial district equivalents per square meter. Broken paving, non-functional lighting, and drainage failures are chronic. The sub-street warrens present a further extreme: pedestrian corridors that were designed as service passages and have been inhabited are lit by a combination of residual infrastructure lighting and informal electrical taps, with no systematic maintenance. Navigating the sub-street warren network on foot requires local knowledge that is not formally documented and is not accessible through any sanctioned mapping system.

The mapping gap is itself a form of infrastructure inequality. The Meridian Navigation Mesh — the city's dominant mapping and wayfinding system, operated by Velorant — provides comprehensive pedestrian routing for Skywalk and street-level corridors in Tier-One through Tier-Three zones. It does not map the sub-street warrens at all. Residents of sub-street communities navigate by informal knowledge, hand-drawn or locally-shared mesh-node maps, and the kind of accumulated spatial memory that comes from living in a place the official city pretends does not exist. This invisibility is not accidental: formally mapping the sub-street pedestrian network would implicitly acknowledge the scale of the population living there, a political acknowledgment that multiple corporate sovereigns have reasons to avoid.
