We identify putative load-bearing structures (bridges) in experimental colloidal systems studied by confocal
microscopy. Bridges are co-operative structures that have been used to explain stability and inhomogeneous
force transmission in simulated granular packings with a range of densities. We show that bridges similar to
those found in granular simulations are present in real experimental colloidal packings. We describe critically
the bridge-finding procedure for real experimental data and propose a new criterion-Lowest Mean Squared
Separation (LSQS)-for selecting optimum stabilisations.
