Right now, the Bluebird- and Jeep- Walker (a "walk" view, which is capable of walking around in the scenery) is unable to walk below bridges. The walker is blocked when the ground elevation suddenly rises to heigth which a human cannot reach by a step. This means while trying to pass beneath a bridge, geo.elevation returns the heigth of the bridge which will obviously stop the walker from moving ahead.
