Simple Icon of a Road Tunnel

This is a straightforward and clean graphic representing a road tunnel. It features a light blue arched entrance with a defined darker blue outline. A road with a white dashed centerline extends into the tunnel, leading to a smaller, distant opening that gives a nice sense of perspective. The design is simple and clear, making it an excellent visual for themes related to infrastructure, transportation, or a journey through a passage.
