The beam bridge (: palkkisilta) is a small bridge that spans the river which connects the northern lake to lake Peräjärvi. The bridge is very narrow and has railings on both sides, it is also high enough that the boat can be sailed under it. Coming in contact with Pena on the beam bridge can be dangerous due to how narrow the bridge is. Make sure to be careful and not hit the railings when driving a vehicle across the bridge, especially the Gifu. The fish trap can be placed under this bridge to catch pike.
