Hub River Road (Gul Bai to Hub Chowki) is a crucial route linking Karachi’s SITE Industrial Area to Hub Chowki in Balochistan. Starting from Gul Bai, the road is heavily used by industrial traffic, with the landscape gradually shifting from urban to arid, reflecting the semi-desert terrain. The road runs near the Hub River and serves as a key trade and transport route between Sindh and Balochistan. It ends at Hub Chowki, a busy junction with checkpoints, marking the transition between the two provinces.
