A barrier system is used to block a travel path. The barriers block and direct paths of vehicular and pedestrian travel. The barriers may be shaped substantially as a truncated pyramid with a base surface and planar sides extending from the edges of the base surface to a top portion, where the cross-sectional area of the base surface is larger than the cross-sectional area of the top portion. The angles of inclination between the planar sides and the interior of the base surface are acute angles. The bollard can be cast from heavy dense materials. The bollard includes at least two overhanging lips on the planar sides of the barrier between the base surface and the top portion. The configurations of the bollards provide improved placement, such as with cranes, hand carts, and other devices. Molds to cast the barriers and hand carts to move the barriers are also disclosed.
