Park, and Oaks Bottom Wildlife Refuge are on the right, and Willamette Park is on the left. In this stretch, Stephens Creek enters from the left. The north–south leg of the Springwater Corridor, a pedestrian and bicycle path, runs parallel to the river along its right bank from Sellwood to the Hawthorne Bridge in central Portland. About from the mouth, the river flows around East, Hardtack, Toe, and Ross islands before reaching the Ross Island Bridge, which carries U.S. Route 26. From Ross Island to the Marquam Bridge, I-5 runs roughly parallel to the river and to its left, and for much of this distance Oregon Route 99E (Southeast McLoughlin Boulevard) follows the river and to its right. About later, the Willamette flows by the Oregon Museum of Science and Industry, which is on the right, then under the Marquam Bridge, which carries I-5. Subsequently, the river passes under the Hawthorne, Morrison, Burnside, Steel, and Broadway bridges in downtown Portland. All carry city streets and pedestrian walkways, and the Steel Bridge carries the Union Pacific Railroad, and the Metropolitan Area Express (MAX) light rail as well. Between the Marquam and Steel bridges, the river flows by Tom McCall Waterfront Park on the left. Between the Hawthorne and Steel bridges, the Eastbank Esplanade and I-5 are on the river's right. Downstream of the Broadway Bridge, the river flows under the Fremont Bridge, which carries Interstate 405 and U.S. Route 30. Between the bridge and Sauvie Island, Route 30 runs roughly parallel to the left of the river between it and Forest Park in the Tualatin Mountains (West Hills). Below this, Swan Island and its marine terminals, run by the Port of Portland, is on the right at about from the mouth, and Balch Creek enters from the left. Near Swan Island, the University of Portland is above the river on a bluff to the right. The Willamette then receives Saltzman and Doane creeks from the left before flowing under the Burlington Northern Railroad Bridge 5.1 at RM 7 (RK 11). The river then flows by a USGS gauging station, which is on the left, and under the St. Johns Bridge, which carries U.S. Route 30 Bypass. Here Portland's Linnton neighborhood is on the left, and its St. Johns neighborhood is on the right. About from the mouth, the river divides to flow around Sauvie Island. Over the final stretch of the
