　　Looking from the top, the sound insulation casing connecting the Tiger-hole Mountain Tunnel on western part of the interchanges completed yesterday. The hole-drilling construction is also near the end. The Tiger-hole Mountain Tunnel is the important part of Hero Mountain Interchanges. At present, the tunnel pavement has been laid and it is expected to open before the end of the year. At that time Hero Mountain Interchanges will connect the Shunhe Viaduct and the Tiger-hole Mountain to provide convenience for citizens.
