Tower Bridge
Logistics Guide

Yes, Tower Bridge is fully accessible via internal lifts in both the North and South Towers. The high-level walkways (including the glass floor sections) are 100% level ($0\text{Hz}$ vibration). The 'Engine Rooms' (located at road level) are also accessible via a separate entrance with a lift. Note that the walk between the towers and the Engine Rooms is about $200\text{ meters}$ on a slight gradient ($3\%$ incline).

Accessible restrooms are located in the North Tower (entrance level), the South Tower, and inside the Engine Rooms. They are standard PRM toilets with $1.5\text{-meter}$ turning radii and emergency pull-cords. They are well-maintained and compliant.

The best drop-off is at the 'North Tower' entrance on Tower Bridge Road ($51.506100, -0.075500$). There is a designated area for drop-offs with a flush curb. From here, the lift to the walkways is just $10\text{ meters}$ away.

It has a 'mechanical and airy' sensory profile. Acoustically, the walkways are medium ($60\text{dB}$), but the Engine Rooms are louder ($75\text{dB}$) with low-frequency mechanical hums. Visually, the glass floor is very high-stimulus. Physically, it is stable ($0\text{Hz}$ on walkways, $5\text{Hz}$ on the bridge road).

Yes, the glass floor is engineered to hold the weight of several elephants; it is perfectly safe for even the heaviest class-3 power-chairs. If you prefer to avoid it, the solid walkways on either side are $1.2\text{ meters}$ wide, providing a 0Hz alternative.

Ask a steward: 'Where is the step-free route to the Engine Rooms?'. They will direct you to the external lift located on the south side of the bridge at river level.
