and fasteners show an alternative although not necessarily preferred structure for attaching an attack resistant device to the top of a barrier such as a jersey barrier preferably the opaque portion is ballistic resistant and or blast resistant in fact the use of opaque materials may result in a higher degree of ballistic resistance and blast resistance due to the decreased use and surface areas of substantially transparent attack resistant material fig5 shows attack resistant barrier 200 including concrete portion 202 end post 220 and fasteners 222 although not shown a front view of barrier 200 would look much like components 17 20 and 21 of barrier 10 except that these components extend over flat surface 204 of concrete portion 202 as shown in fig5 the concrete portion has been modified from the standard jersey barrier shape to provide a flat mounting surface for the attack resistant device instead of fitting over the barrier portion as a cap the attack resistant device is mounted to a major surface of the barrier by fasteners 222 potentially providing additional strength in the connection between the barrier portion and the attack resistant device portion the use of armor panels not shown but similar to panels 17 allows light to pass thru the attack resistant barrier in the direction of arrow l so that people protected by the barrier can see through it to the unprotected side present invention means at least some embodiments of the present invention.
