Stepping on the round sensor to will extend the bridge
Some of you who walk or fly around sovereign sim may have noticed the island in the middle of the lake, but what they may not know is you don't have to fly or jump in a boat to get there. A simple way is to walk across on foot. Once you stand or walk on the pressure point at the shore an automatic bridge will extend across the water for you to stroll along to the center.
The bridge has a detector so after a few second of no one standing on it, the bridge will detract leaving the lake clear again for sailing and speed boating.
