Miri River is the body of water that splits Miri Peninsula and the mainland Miri, flowing out to sea from inland, curving at Lutong Town. It is incorrectly marked as Sungai Baong in some online maps, while other references online confused it with Baram River.
The Miri Long Jetty was a mile long and stretches out into the sea. This jetty was built so that cargo is easily offloaded from ships to Miri at the tip of the Miri Peninsular. The Long Jetty was a considerable place of interest in the 1970 to late 1990s.
The old Piasau bridge was a Bailey bridge at Piasau linking from the peninsular to Piasau at the point closest to the sea. The bridge, originally made of steel and wood with a single lane to handle the occasional vehicle traffic crossing, has seen several upgrades over the years.
