In a two-dimensional electron system confined in a wide quantum well, we observe an insulating phase that manifests a dramatic evolution as the electron distribution is tuned from single-layer like system to an interacting bilayer system. The data strongly suggest that interlayer interactions play a dominant role and are able to stabilize a correlated bilayer Wigner crystal at total filling factor ν as large as 0.54 (ν>1/4 in each layer).
